Rabbit Syphilis / Vent Disease

Rabbit syphilis, also known as vent disease or treponematosis, is a sexually transmitted bacterial infection caused by Treponema cuniculi, a spirochete bacterium closely related to the organism that causes syphilis in humans. Despite the similar name, rabbit syphilis is species-specific and cannot be transmitted to humans or other animals. This condition primarily affects the genital region but can also spread to other areas of the body including the nose, lips, chin, and eyelids. Rabbit syphilis is most commonly seen in breeding rabbits and sexually mature intact adults, though it can occasionally occur in pet rabbits that have had contact with infected animals.

The causative organism, Treponema cuniculi, is transmitted through direct contact, primarily during mating. The bacterium can also spread through contact with contaminated bedding or through mother-to-offspring transmission during birth or nursing. Once the organism enters the body, it causes characteristic lesions that begin as small, reddened areas and progress to crusty sores. The incubation period can range from three to sixteen weeks, which means infected rabbits may transmit the disease before showing any clinical signs.

Rabbit syphilis significantly impacts the health and welfare of affected rabbits, causing discomfort, pain, and potential complications if left untreated. The lesions can become secondary infected with other bacteria, leading to more severe skin damage and systemic illness. In breeding operations, this disease can spread rapidly through a colony if not identified and treated promptly. The condition also affects quality of life, as the lesions can make urination and defecation painful, potentially leading to reduced food intake and subsequent gastrointestinal complications including GI stasis.

The good news is that rabbit syphilis is highly treatable when diagnosed early and managed appropriately by a rabbit-savvy veterinarian. Antibiotic therapy, specifically penicillin injections, is extremely effective at eliminating the infection. However, because rabbits hide illness and the early stages of this disease can be subtle, regular health checks are essential for early detection. With proper treatment, most rabbits make a complete recovery, though scarring may occur in cases where lesions were severe. Prevention through quarantine of new rabbits and regular health monitoring is crucial for protecting rabbit colonies from this contagious disease.

The primary cause of rabbit syphilis is infection with Treponema cuniculi, a spiral-shaped bacterium belonging to the spirochete family. This organism is an obligate pathogen, meaning it can only survive and reproduce within a living host. The bacterium is highly adapted to rabbits and has evolved specifically to infect this species. Transmission occurs most commonly through direct sexual contact during breeding, which is why the disease is classified as a venereal infection. The organism enters the body through mucous membranes or small breaks in the skin, establishing infection at the initial site of contact before potentially spreading to other areas.

Unlike many bacterial infections, rabbit syphilis does not have a significant genetic or hereditary component. Any rabbit can become infected if exposed to the causative organism, regardless of breed or genetic background. However, the immune status of individual rabbits can influence susceptibility and disease severity. Rabbits with compromised immune systems due to stress, malnutrition, or concurrent illness may be more susceptible to infection and may develop more severe clinical signs. Young rabbits born to infected mothers can acquire the infection during birth or through close contact during nursing.

Environmental and lifestyle factors play a significant role in the transmission and spread of rabbit syphilis. Breeding operations where rabbits are regularly mated face the highest risk, as sexual contact is the primary transmission route. Overcrowded housing conditions increase the likelihood of disease spread, as do poor sanitation practices that allow contaminated bedding or surfaces to serve as fomites. The bacterium can survive for short periods outside the host, making environmental contamination a secondary transmission concern. Stress from inadequate housing, improper diet, or social conflicts can compromise immune function and increase susceptibility to infection.

Several risk factors increase the likelihood of a rabbit developing vent disease. Intact, sexually mature rabbits face the greatest risk, particularly those actively used for breeding. Rabbits in group housing situations where mounting behavior occurs, even among same-sex pairs, can transmit the infection. New rabbits introduced to a colony without proper quarantine procedures pose a significant risk to established populations. Rabbits obtained from sources with unknown health histories, including some pet stores and breeders, may harbor the infection without showing obvious signs.

The mechanism of disease development involves the spirochete penetrating the skin or mucous membranes at the site of initial contact. Following an incubation period of three to sixteen weeks, the organism multiplies locally, causing inflammation and the characteristic skin lesions. The bacteria then spread through the lymphatic system and bloodstream to other susceptible areas, particularly regions with thin skin and mucous membranes such as the nose, lips, and eyelids. The body's immune response to the infection causes much of the visible tissue damage, as inflammation and immune cell infiltration contribute to lesion formation. Without treatment, the infection can persist for extended periods, with lesions waxing and waning but never fully resolving.

Early warning signs of rabbit syphilis are often subtle and easily overlooked, which is why regular health checks are essential for early detection. The first indication of infection may be mild redness or swelling around the genital area, anus, or vent region. Owners may notice their rabbit paying increased attention to their hindquarters, with excessive grooming or licking of the affected area. Slight changes in behavior, such as reluctance to be handled around the rear end or mild discomfort when using the litter box, can indicate early disease. Because rabbits instinctively hide signs of illness, these subtle changes warrant close inspection of the genital region. Any unexplained redness, swelling, or moisture around the vent should prompt veterinary consultation.

The most common and recognizable symptoms of rabbit syphilis are the characteristic skin lesions that develop at sites of infection. These lesions typically begin as small, reddened areas that progress to raised, crusty sores with a distinctive appearance. The edges of the lesions are often raised and well-defined, with a crusty or scabby surface covering an ulcerated area beneath. In the genital region, lesions may appear on the vulva in females or the prepuce and scrotum in males. The area around the anus is also commonly affected. Lesions may produce a discharge and have an unpleasant odor, particularly if secondary bacterial infection is present.

Behavioral changes in rabbits with vent disease often reflect the discomfort associated with the lesions. Affected rabbits may become reluctant to urinate or defecate, potentially leading to reduced food intake as the rabbit associates eating with subsequent discomfort. Lethargy and decreased activity levels are common as the rabbit conserves energy while fighting the infection. Rabbits may show reduced interest in grooming, or conversely, may overgroom the affected areas, potentially causing additional skin damage. Changes in social behavior, including reduced interest in bonded partners or increased irritability when approached, can indicate pain or discomfort. Teeth grinding, a sign of pain in rabbits, may be observed in more severe cases.

Physical signs of rabbit syphilis extend beyond the primary genital lesions. As the infection spreads, secondary lesions commonly appear on the face, particularly around the nose, lips, chin, and eyelids. These facial lesions have the same crusty, ulcerated appearance as genital lesions and can cause significant discomfort. The nose may appear swollen or crusty, and lesions around the eyes can cause excessive tearing or discharge. In severe cases, lesions may develop on the feet or legs. Affected rabbits may show weight loss due to reduced appetite, and their coat condition may deteriorate due to decreased grooming. Swelling of regional lymph nodes may be detectable on physical examination.

Symptom progression in untreated rabbit syphilis follows a somewhat unpredictable course. Initial lesions may appear to improve spontaneously, giving the false impression that the infection is resolving. However, without treatment, the disease enters a latent phase before recurring with new or worsening lesions. This cycle of apparent improvement and relapse can continue for months or even years. Over time, the lesions may become more extensive and severe, with increasing risk of secondary bacterial infection. Chronic cases may develop significant scarring and permanent tissue changes. The prolonged stress of chronic infection can trigger secondary health problems, including GI stasis, as the rabbit's overall condition deteriorates.

Emergency symptoms requiring immediate veterinary attention include severe swelling of the genital area that impairs urination or defecation, signs of systemic illness such as fever or severe lethargy, and any indication that the rabbit has stopped eating or producing fecal pellets. Not eating for twelve hours or more is always an emergency in rabbits, regardless of the underlying cause. Extensive lesions with significant discharge or foul odor suggest severe infection requiring urgent treatment. If secondary GI stasis develops, evidenced by no fecal output, a hunched posture, or teeth grinding, immediate veterinary care is essential. Open-mouth breathing, which indicates severe respiratory distress, is a dire emergency requiring immediate intervention.

Diagnosis of rabbit syphilis begins with a thorough physical examination by a rabbit-savvy veterinarian. Finding a veterinarian experienced with rabbits is crucial, as not all practitioners are familiar with this species-specific disease. During the examination, the vet will carefully inspect the genital region, anus, nose, lips, and eyelids for characteristic lesions. The distinctive appearance of the crusty, well-defined lesions in typical locations often provides strong presumptive evidence of vent disease. The veterinarian will ask about the rabbit's history, including breeding status, recent contact with other rabbits, and any previous health issues. Information about when symptoms first appeared and how they have progressed helps guide diagnostic decisions.

Definitive diagnosis of rabbit syphilis requires laboratory testing to identify the causative organism. Dark-field microscopy examination of material collected from lesions can reveal the characteristic spiral-shaped Treponema organisms. This test provides rapid results but requires specialized equipment and expertise. Serological testing to detect antibodies against Treponema cuniculi is available and can confirm infection even in cases where organisms are difficult to visualize. PCR testing, which detects the genetic material of the bacterium, is highly sensitive and specific but may not be available at all laboratories. In some cases, biopsy of lesion tissue with histopathological examination may be performed to rule out other conditions and confirm the diagnosis.

Several other conditions can produce lesions similar to those of rabbit syphilis, making differential diagnosis important. Myxomatosis, a viral disease, can cause swelling and lesions around the eyes, nose, and genitals, though the appearance differs from syphilitic lesions. Pasteurella infections can cause abscesses and skin lesions, particularly around the face. Mite infestations may cause crusty lesions, particularly on the ears and face. Urine scald from improper housing or urinary problems can cause redness and irritation of the genital area. Hutch burn, caused by contact with soiled bedding, produces similar perineal irritation. Skin cancer or other tumors must be considered in older rabbits with unusual lesions. Your veterinarian will use the clinical appearance, history, and laboratory testing to distinguish rabbit syphilis from these other conditions.

Once rabbit syphilis is confirmed, the veterinarian will assess the extent of infection and check for complications. This evaluation may include blood tests to assess overall health status and identify any secondary effects of chronic infection. If GI stasis is suspected, abdominal palpation and possibly radiographs may be performed to evaluate gut motility. The veterinarian will also examine any bonded partners or colony mates, as they may be infected even if not yet showing symptoms. Documentation of lesion locations and severity helps monitor treatment response. The results of all testing guide treatment decisions and help establish a prognosis for recovery.

Emergency and immediate treatment for rabbit syphilis focuses on addressing any complications while initiating antibiotic therapy. If the rabbit has stopped eating or shows signs of GI stasis, supportive care including fluid therapy, gut motility medications, and syringe feeding with critical care formula takes priority alongside treating the underlying infection. Pain management is essential, as the lesions can be quite uncomfortable. Meloxicam is commonly used for pain relief in rabbits at appropriate doses determined by your veterinarian. Any secondary bacterial infections of the lesions require attention, potentially with topical treatments to clean and protect the affected areas while systemic antibiotics address the primary infection.

The cornerstone of medical treatment for rabbit syphilis is antibiotic therapy with penicillin G. Unlike oral penicillins, which are dangerous for rabbits due to disruption of gut flora, injectable penicillin G is safe and highly effective against Treponema cuniculi. The standard treatment protocol involves a series of penicillin G injections, typically administered subcutaneously. Treatment duration is usually three weeks, with injections given weekly or more frequently depending on the protocol your veterinarian follows. It is absolutely critical to use only injectable penicillin and never oral penicillin or amoxicillin, as oral administration of these antibiotics is potentially fatal to rabbits. Alternative antibiotics such as chloramphenicol may be used if penicillin is not available or if the rabbit has a documented reaction.

Surgical intervention is rarely needed for rabbit syphilis, as antibiotic therapy is highly effective. However, in cases with severe secondary bacterial infection or abscess formation, surgical drainage or debridement may be necessary. Any surgical procedures require a veterinarian experienced with rabbit anesthesia, as rabbits have unique anesthetic risks. Unlike dogs and cats, rabbits should not be fasted before surgery because their digestive system requires continuous function. If extensive scarring has caused structural problems, such as narrowing of the urethral or anal openings, corrective procedures may be considered once the infection is fully resolved.

Supportive care plays a vital role in treatment success and overall recovery. Maintaining nutrition is critical, as rabbits must continue eating to keep their digestive system functioning properly. If appetite is reduced, syringe feeding with a commercial critical care formula ensures adequate nutrition and fiber intake. Fresh water must always be available, and some rabbits benefit from subcutaneous fluid administration to maintain hydration. Keeping the affected areas clean and dry promotes healing; gentle cleaning with saline solution may be recommended. Providing soft, clean bedding reduces irritation to lesions, and keeping the environment warm and stress-free supports immune function and recovery.

Complementary treatments may support healing alongside primary antibiotic therapy. Topical treatments may be applied to lesions to keep them clean and promote healing, though nothing should be used without veterinary approval. Ensuring optimal nutrition through unlimited grass hay, appropriate pellets, and fresh leafy greens supports the immune system's ability to fight infection. Reducing stress through quiet housing, maintaining bonded relationships when possible, and minimizing handling during active infection helps the rabbit focus energy on recovery. Some practitioners may recommend probiotics to support gut health during and after antibiotic treatment, though injectable penicillin has minimal impact on intestinal flora compared to oral antibiotics.

Treatment decisions should consider several factors including the severity of infection, the rabbit's overall health status, and practical considerations for the owner. Cost of treatment is generally reasonable, as penicillin is inexpensive, though multiple veterinary visits for injections add to the total expense. Some owners may learn to administer subcutaneous injections at home under veterinary guidance, reducing visit costs. The rabbit's quality of life during treatment is usually good, as antibiotic therapy begins working quickly and lesions often show improvement within days to weeks. Treatment of all in-contact rabbits, even those not showing symptoms, is typically recommended to prevent ongoing transmission and reinfection.

Recovery from rabbit syphilis typically progresses well with appropriate antibiotic treatment. Most rabbits show noticeable improvement in their lesions within one to two weeks of starting penicillin therapy. The crusty appearance of lesions begins to resolve, and new, healthy tissue starts to form beneath. Complete healing of lesions usually occurs within four to eight weeks, depending on severity. During the first week of treatment, appetite should improve as discomfort decreases, and normal eating and litter box habits should return. By the second week, most rabbits are significantly more comfortable and active. Full recovery with complete resolution of all lesions is expected in the majority of cases when treatment is completed as prescribed.

Post-treatment care focuses on monitoring for complete resolution and preventing recurrence. Continue administering all medications exactly as prescribed, even if the rabbit appears fully recovered before the treatment course is complete. Stopping antibiotics early can allow resistant organisms to survive and cause relapse. Keep follow-up appointments so your veterinarian can confirm that all lesions have healed and no new ones have developed. During recovery, maintain excellent hygiene in the rabbit's living area, with frequent bedding changes and cleaning of surfaces. Monitor food intake and fecal output daily, as any reduction warrants attention. Limiting contact with other rabbits during and immediately after treatment prevents disease spread.

Several factors influence prognosis and recovery outcomes. Rabbits diagnosed and treated early, before extensive lesions develop, typically recover most quickly and completely. Older rabbits or those with concurrent health issues may take longer to heal. The completeness of the treatment course significantly affects outcomes; abbreviated or inconsistent treatment increases recurrence risk. Rabbits with secondary bacterial infections may require extended treatment and have longer recovery times. Overall health and immune status affect healing speed, making proper nutrition and stress reduction important contributors to recovery. While most rabbits recover without complications, some may develop scarring in areas of severe lesions.

Long-term outlook for rabbits that complete treatment for syphilis is excellent. The infection is curable, and recurrence is uncommon when treatment is completed properly and reexposure is prevented. Some rabbits may have permanent scarring from severe lesions, but this typically does not affect function or quality of life. Monitoring should continue for several months after treatment ends, with regular inspection of previously affected areas for any sign of recurrence. Breeding rabbits should not be used for mating until fully recovered and cleared by a veterinarian. If the rabbit lives with bonded partners, those rabbits should also complete treatment to prevent ongoing transmission. With proper treatment and prevention measures, rabbits with a history of syphilis can live normal, healthy lives.

Primary prevention of rabbit syphilis centers on preventing exposure to infected animals and maintaining a closed, healthy colony. The most effective prevention strategy is to avoid introducing the organism into your rabbit population. Source rabbits only from reputable breeders or rescues that can provide health histories and have no known history of vent disease. Avoid acquiring rabbits from situations where health status is unknown or disease history is questionable. If you breed rabbits, maintain strict biosecurity protocols and never use breeding stock with any history of the disease. Spaying and neutering pet rabbits eliminates the primary transmission route and provides numerous additional health benefits including prevention of reproductive cancers.

Environmental prevention requires attention to housing, hygiene, and management practices. Maintain clean living spaces with regular bedding changes and sanitation of all surfaces. Treponema organisms do not survive long outside the host, so thorough cleaning between occupants effectively eliminates environmental contamination. If housing multiple rabbits, design setups that prevent unwanted breeding or mounting behavior, which can transmit the infection. Keep intact males and females separated unless intentional breeding is planned. Environmental stress suppresses immune function and increases susceptibility to infection, so provide appropriate space, proper ventilation, comfortable temperatures, and enrichment for all rabbits.

Dietary factors support immune function and overall health, helping rabbits resist infection. The foundation of rabbit nutrition is unlimited grass hay, which should comprise at least eighty percent of the diet. Timothy hay, orchard grass, and other grass hays provide essential fiber for digestive and dental health. Offer measured amounts of quality pellets appropriate for the rabbit's age and size. Fresh leafy greens should be provided daily, including varieties such as romaine lettuce, cilantro, and parsley. Avoid sudden dietary changes, which can disrupt gut flora and cause GI problems. Clean, fresh water must always be available. A rabbit on an optimal diet has better immune function and overall resilience to infectious diseases.

Regular health maintenance helps detect problems early and maintains optimal health. Establish a relationship with a rabbit-savvy veterinarian for routine care and to have a trusted resource when problems arise. Annual wellness examinations allow professional assessment of your rabbit's health and provide opportunities to discuss any concerns. Implement a quarantine protocol for any new rabbits entering your home, isolating them for at least thirty days while monitoring for signs of disease. During quarantine, have new rabbits examined by a veterinarian and tested for contagious diseases if possible. Regular weight monitoring at home helps detect early signs of illness that might otherwise go unnoticed.

Early intervention through vigilant monitoring can prevent disease spread and improve outcomes. Perform regular health checks at home, including inspection of the genital area, nose, lips, and eyelids. Know what normal looks like for your rabbit so you can recognize abnormalities quickly. Any redness, swelling, or crusty lesions should prompt veterinary consultation. If you have multiple rabbits and one is diagnosed with syphilis, have all rabbits examined and consider preventive treatment for the entire group. Prompt treatment of infected individuals prevents spread to others and resolves the condition before severe lesions develop. Document any health changes in a log, which helps track patterns and provides useful information for your veterinarian.

Daily management of a rabbit recovering from or living with treated syphilis requires attention to several care aspects. Monitor the rabbit's appetite and food consumption daily, ensuring they continue eating hay, pellets, and greens normally. Check the litter box to confirm normal fecal output; healthy rabbits produce numerous round, firm pellets daily. If your rabbit is still receiving treatment, administer medications exactly as prescribed and maintain the treatment schedule. Perform gentle visual inspection of previously affected areas daily to monitor healing and watch for any new lesions. Keep a simple log of observations including appetite, activity level, and lesion appearance, which helps track progress and identify any setbacks early.

The home environment should support healing and minimize stress during recovery. Provide a clean, comfortable living space with soft bedding that does not irritate healing skin. Fleece liners or soft paper-based bedding are gentler than straw or wood shavings for rabbits with healing lesions. Ensure the rabbit has adequate space to move around comfortably while recovering. Temperature control is important; keep the environment between 60-70°F and protect the rabbit from drafts and extreme temperatures. Rabbits are sensitive to heat and can develop heat stress, so provide cooling options during warm weather. A quiet location away from household chaos reduces stress and supports healing. Provide hiding spots where the rabbit can retreat when feeling vulnerable.

Maintaining quality of life during treatment and recovery is essential for the rabbit's wellbeing. Continue providing enrichment activities such as tunnels, platforms, and safe chew toys. Social interaction is important; spend time sitting near your rabbit, offering gentle pets if welcomed, and maintaining your bond. If your rabbit has a bonded partner and both have completed treatment, they can remain together, as social companionship provides emotional benefits. Safe supervised exercise in a rabbit-proofed space helps maintain muscle tone and mental stimulation. Watch for signs of good quality of life including bright, alert eyes, interest in food and surroundings, grooming behavior, and relaxed body postures. Decreased activity, hunched posture, or disinterest in normal activities may indicate pain or complications requiring veterinary attention.

Ongoing monitoring and care should continue even after treatment is complete. Continue regular home health checks, paying particular attention to areas that were affected. Watch for any new lesions that might indicate treatment failure or reinfection. Maintain regular veterinary check-ups, with follow-up visits as recommended by your veterinarian to confirm complete resolution. Weigh your rabbit weekly using a kitchen or postal scale; unexplained weight loss can indicate problems before other signs are visible. Monitor eating habits, activity levels, and litter box output as ongoing indicators of health. If you notice any concerning changes, contact your veterinarian promptly rather than waiting to see if problems resolve on their own.

Caregiver support and resources are valuable for rabbit owners managing this condition. Connect with rabbit welfare organizations such as the House Rabbit Society for educational materials and support. Online communities of rabbit owners can provide emotional support and practical advice from others who have experienced similar situations. Exotic veterinary care can be expensive, so budget for follow-up visits and potential complications. If cost is a concern, discuss this with your veterinarian, who may be able to suggest cost-effective approaches to care. Caring for a sick rabbit can be stressful, so don't neglect your own wellbeing. Reach out to rabbit-owning friends or support groups when you need encouragement. Most cases of rabbit syphilis resolve successfully with treatment, and the prognosis is excellent for rabbits that complete their medication course.

Rabbit syphilis does not show strong breed predisposition, as all rabbit breeds are equally susceptible to infection with Treponema cuniculi. The primary risk factors relate to breeding status and exposure opportunities rather than genetic factors. However, certain categories of rabbits face higher risk due to lifestyle factors. Breeding rabbits of any breed have the highest risk because sexual contact is the primary transmission route. Breeds commonly used in commercial or show breeding programs may have higher exposure rates simply due to more frequent breeding activity. Giant breeds, dwarf breeds, lop-eared varieties, and all other breed types share equal susceptibility when exposed to the organism.

Moderate-risk categories include intact adult rabbits that are not actively bred but may have contact with other rabbits. Rescue rabbits with unknown histories may carry latent infections acquired before adoption. Rabbits in group housing situations where mounting behavior occurs, even among neutered animals or same-sex groups, have some transmission risk. Show rabbits that travel to events where they may have indirect contact with other rabbits face potential exposure, though direct contact is required for transmission. Pet rabbits that live as single house rabbits with no contact with other rabbits have minimal risk. Age does not appear to significantly affect susceptibility, though very young or elderly rabbits may have less robust immune responses.

Screening recommendations focus on breeding animals and new acquisitions rather than breed-specific testing. Any rabbit intended for breeding should be examined for lesions before mating and ideally tested serologically for Treponema antibodies. New rabbits entering an established colony should complete a quarantine period with veterinary examination before joining the group. Breeding operations should implement routine screening protocols as part of their health management program. For pet owners acquiring rabbits, ask about health history and request veterinary records when available. Rabbits from rescues that perform intake health examinations provide more reliable health information than those from sources without health screening. If you adopt a rabbit with unknown history, have a veterinarian examine them promptly and monitor for any signs of disease during the initial settling-in period.

Several conditions commonly co-occur with or relate to rabbit syphilis. Secondary bacterial infections frequently complicate the crusty lesions of vent disease, with opportunistic bacteria colonizing damaged skin. Staphylococcal or other skin infections may require additional antibiotic treatment alongside syphilis therapy. GI stasis is a critical related condition that may develop when a rabbit with syphilis stops eating due to discomfort or stress. Because rabbits require continuous gut motility, any condition that reduces appetite poses a risk of secondary GI stasis, which can be life-threatening within twenty-four to forty-eight hours. Stress-related immunosuppression from chronic infection can make rabbits more susceptible to other infectious diseases. Maintaining nutrition and managing pain helps prevent these secondary complications.

Several conditions produce symptoms similar to rabbit syphilis and must be differentiated for proper treatment. Myxomatosis causes swelling and lesions around the face and genitals but is a viral disease with very different treatment and prognosis; it is reportable in many areas and often fatal. Pasteurella infections can cause skin abscesses and facial lesions but typically have a different appearance and may be accompanied by respiratory symptoms. Urine scald causes irritation and fur loss around the genital area from contact with urine, usually related to mobility problems, obesity, or improper housing. Hutch burn is similar, resulting from contact with soiled bedding. Skin mite infestations cause crusty lesions, particularly on ears and face. Tumors or cancers can produce unusual masses or skin changes. Your veterinarian will differentiate these conditions through examination and appropriate testing.

Potential complications of rabbit syphilis include scarring from severe or chronic lesions, which may occasionally cause structural issues if scarring narrows natural openings. Secondary abscesses may form if bacteria invade damaged tissue deeply. Chronic stress from prolonged infection can suppress immune function and predispose the rabbit to other health problems. If severe genital lesions impair urination or defecation, life-threatening complications can develop. Hepatic lipidosis, a serious liver condition, can result from prolonged anorexia in affected rabbits. Prevention of complications relies on early diagnosis and treatment, maintaining nutrition throughout the treatment period, and monitoring closely for any signs of secondary problems. With appropriate care, serious complications are uncommon and most rabbits recover fully.
