Rabbit spirochete disease

The pathogenic Treponema burgdorferi is a slender spiral microorganism, gram-negative, but chromatic aberration. The exudate or lymph smear was fixed and Giemsa staining had a good effect. Tissue sections can be stained by Warthin method. The shape and movement of the spirochete can be clearly observed with a dark field microscope, so the disease can be diagnosed.

The epidemic characteristics of the disease only occurred in rabbits and rabbits, and the pathogen mainly existed in the tissue of the disease. Contaminated bedding grass, utensils and feed are the medium of transmission. Mainly in the breeding through the reproductive tract infection, so more common: adult rabbits, young rabbits are very few. The incidence of female rabbits of childbearing age was higher than that of male rabbits, and the incidence of female rabbits was higher than that of caged rabbits. When the disease was prevalent in rabbits, the incidence was high, but almost no one died.

The incubation period of symptoms and pathological changes was 2-10 weeks. After the onset of the disease is a chronic process, which can last for several months. There were no obvious systemic symptoms, only local lesions were seen. The glans, prepuce and scrotal skin of the male rabbit, the skin and mucosa of the labia and anus of the female rabbit are red and swollen, and large millet nodules are formed. later nodules and swollen parts are moist, there are mucopurulent secretions and brown scabs, slightly sunken ulcer surfaces can be seen when the scab is peeled off, and the edge of the ulcer is uneven and easy to bleed. Because of scratching, diseased rabbits can bring pathogens from some of the diseased secretions to other parts such as nose, eyelids, lips and claws. In chronic patients, the disease is dry and scaly, with slight protuberances, necrotic foci in the ninth testicle, and often enlarged inguinal and follicular lymph nodes. The disease had little effect on the libido of rabbits, but the female rabbits lost the ability of mating, the conception rate decreased, and the vitality of the newborn rabbits was poor. The diagnosis of this disease can be made by the typical lesions of the external genitalia, but the diagnosis should be based on the detection of pathogens.

Strictly prevent and control the introduction of diseased rabbits, and it is strictly forbidden to breed diseased rabbits or suspected diseased rabbits. After discovering sick rabbits, they should be treated or eliminated in time, thoroughly remove dirt, and disinfect rabbit cages and utensils with 1%-2% caustic soda water or 2%-3% soda water. In the early stage of diseased rabbits, 5% solution of neo-arsine vannamine (914) mixed with sterilized distilled water was injected intravenously, 40 mg / kg body weight, repeated once after 2 weeks if necessary. At the same time, 500000 units of penicillin were injected intramuscularly twice a day for 5 days. After rinsing the lesion with 0.1% potassium permanganate solution or 2% boric acid solution, apply iodoglycerin or penicillin ointment.
