Prevention and treatment of Taize's disease in rabbits

Recently, many cases have been received from all over the country. Farmers think that diarrhea is caused by common diarrhea and coccidiosis, but it is actually caused by Bacillus hairy, which causes not only the sudden death of young rabbits, but also a lot of deaths of female rabbits.

Overview

The disease is caused by Bacillus hairy, characterized by severe dysentery, dehydration and rapid death.

Pathogen

The pathogen of rabbit Taize's disease: Bacillus hairy is a strict intracellular parasite, the cell is slender, gram-negative, Giemsa staining is good. This bacteria is pleomorphic, has flagella, can move and can produce spores. although the bacteria is easy to autolysis in vitro, the liver materials of infected animals are still infectious after being stored at minus 10 degrees Celsius for 16 months. general disinfectants (formaldehyde, peracetic acid, sodium hypochlorite, phenol, bromogeramine, etc.) can kill the pathogen within 5 minutes, but its infectivity can be maintained for 1 year after spore formation.

Epidemiological characteristics

The disease exists not only in rabbits, but also in a variety of experimental animals and livestock. The morbidity and mortality are very high, the spectrum of infected animals is wide, and rabbits of all ages can be infected. The period from late autumn to early spring is a frequent season. Pathogens are excreted from feces, polluting appliances, environment and feed, drinking water, etc., and are infected through the digestive tract. Rabbits do not get sick immediately after infection, but invade the intestinal tract and proliferate slowly, when the resistance of the body decreases. Stress factors such as overcrowding, overheating, climate upheaval, long-distance transportation and improper feeding management are often the causes of the disease.

Symptoms and pathological changes

Sudden onset, severe diarrhea, brown stool, depressed spirit, loss of appetite, rapid dehydration; early paste with blisters, later clear water; hair disorder, acute death is generally 12 Mui 48 hours. Bear the rabbit poor appetite, growth stagnation, weight loss, weakness.

Pathological changes

1, liver yellowing, carefully look at the bleeding spot, some cases can not see the bleeding spot.

2. Necrotizing hemorrhagic enteritis.

3. Cecum, anterior colon and posterior ileum, intestinal mucosa atrophy and necrosis, serosa surface congestion, bleeding, some even yellow wrinkles due to necrosis, cecal worms protruding blood, cecum and colon contents are liquid, often contain blood.

4. Spleen atrophy.

5. Myocardial whitening.

Prevention

1. Strengthen feeding and management, strictly implement veterinary health and epidemic prevention measures for rabbits at ordinary times, do a good job of killing rats, prevent rats from entering rabbit houses, feed and equipment rooms, forage and bedding rooms, and reduce and eliminate various stress factors as far as possible. It is difficult to eliminate the disease in large infected fauna. Only early detection and elimination of sick animals, as well as timely and regular disinfection. In a small rabbit farm, when the disease is diagnosed, it should be isolated in time and resolutely eliminated without therapeutic value. Rabbit houses, cages and utensils are thoroughly disinfected (flame disinfection, show point or bright spot disinfection). Dead rabbits and excreta should be burned or buried in time to control the spread of pathogens.

2. Mix 400 jin of water with Tuan + Sihuang Zhili granule and drink continuously for 3-5 days.

Treatment scheme

1. Tuan + doxycycline hydrochloride + Sihuang Zhili granule

2. Shutan + doxycycline hydrochloride + Sihuang Zhili granule

3. Shoutan + doxycycline hydrochloride + Miyitai

In any of the above schemes, add 200 jin of water and drink continuously for 3-5 days (after the onset of the disease, the rabbit does not eat well), drink more water after being cured, and drink 0.5% sugar saline for 3-5 days.
