Cat Leprosy (Leprosy) is a kind of Feline skin granulomatous tuberous infection, is a rare disease, but the cat skin than any other animal feed more susceptible. Because from wild animals or rats were isolated from rat leprosy bacili, some think rats infected cats leprosy bacili may.
The reason.
The cat in the case of the separation of leprosy mycobacteria mice or rats after inoculated with mice, leprosy exactly the same symptoms, so people think rats with leprosy leprosy is same pathogen cat. In addition, lesions in the head and limbs are easily rat, bite the infection that a cat is believed to be the rodents and contact, by their bite. But, this kind of bacteria infection experiment of cat artificial but often ended in failure. People with leprosy, infection with low immunity function. But with this cat is low, the immune function is unclear. The cat breed, age and gender and incidence and independent.
The symptoms.
1 lesions seen in the body, lesions, but most any part in the head, neck and limbs and susceptible to mice bite or multiple single part. The diameter is 5-35mm round or oval RouYang subcutaneous nodules or become soft, natural healing. Abscess Although sometimes surface skin lesions, but in most cases the normal form fistula or ulcers or granuloma. No difficulties, common local lymph nodes.
2 systemic symptom, body in good condition, usually caused by occasionally systemic infections, with multiple skin lesions, liver, lienal lung and viscera can be formed as a general condition, granuloma deterioration.
The laboratory.
1 directly specimen smear: direct pressure on the slides in lesions, gram’s staining or together – in the organization’s dyeing, mass and LangHanShi giant cell observed in large amounts of gram-negative mycobacteria. A similar quantity of cutaneous tuberculosis bacteria, find difficult.
2 check: tuberous and pathology, and diffuse dermatitis with different levels of ulcer and necrosis or partial calcification of granuloma or purulent granuloma dermatitis. Many nuclear leukocytes, lymphocytes and plasma cells infiltrating, sometimes can be observed LangHanShi giant cells. Also visible in the lymph node containing the mycobacteria and epithelioid cells. A similar cutaneous tuberculosis in common, but cats caseating necrosis leprosy is extremely rare.
3 test: the animal inoculation, so can’t train bacteria infection when using animal inoculation of emulsion. As with tuberculosis, guinea pigs for difference, the cat mice inoculated with leprosy confirmation, the bacterium will cause death inoculation guinea pigs in guinea pigs, n/med tuberculosis bacterium can produce characteristic changes inoculation. In addition the bacteria to mice inoculated with cat, will cause leprosy and rat leprosy in the same lesions, local and nearby lymph nodes vaccination can produce contains a large number of the bacteria.
The diagnosis.
1 case with reference to the diagnosis of inspection.
2 need and tuberculosis, atypical mycobacteria granulomas, foreign bodies, deep fungus disease, chronic bacterial infections, tumor (mast cells, tissue, ball and lymphoma identified).
The treatment.
1 surgical excision of law: and health organization of a single lesion, surgical resection is the preferred method of clinical treatment.
2: all kinds of people use chemical treatment of leprosy medications (dapsone 50 ~ 100mg/kg/day, rifabutin, 5mg/kg/day) can be used in the treatment of leprosy, but the cat doesn’t exactly curative effect. In addition, dapsone will cause hemolytic anemia and poisoning symptoms (note). Will directly into lesions streptomycin within it also has effect.
