Symptoms of colibacillosis in rabbits:

(1) the most acute disease in rabbits, sudden death without any symptoms.

(2) in acute disease rabbits, most of them were depressed at the initial stage, their appetite was poor and their abdomen was distended, and their feces were small in strings with transparent and gelatinous mucus, followed by watery diarrhea with no blood and odour Anal, hind limbs and other fur by feces pollution.

(3) cold limbs, molars, salivation, sunken eyes, rapid weight loss, dehydration, 1-3 days death.

Rabbit E. coli treatment method: the best way to treat Rabbit E. coli is to first isolate bacteria from dead rabbits to do drug sensitivity test and select specific drugs for treatment.

(1) treatment with antibiotics and sulfonamide. For example: streptomycin, 0.5-10,000 units per kilogram of body weight, intramuscular injection twice a day for 3-5 days. Chloramphenicol, 50.100 mg, twice daily intramuscularly for 3-5 days, 0.1 g, 2-3 times daily orally for 5 days. Also can use garlic tincture each time 2-3 milliliters orally, every day 2 times, use continuously 3 days.

(2) if possible, the E. coli isolated in this field can be used to make Aluminum hydroxide vaccine for preventive injection, and the 20-30-day-old rabbits can be intramuscularly injected with 1 ml of the vaccine.

The epidemic characteristics of E. coli in rabbits are as follows:

(1) the disease can occur all year round, and it can be caused by toxin produced by pathogenic E. coli both from inside and outside. The disease mainly infects 20-day-old and pre-and post-weaning rabbits and young rabbits, adult rabbits rarely develop the disease. Morbidity and mortality are high.

(2) E. coli was mainly excreted from the diseased rabbits. The virulence of E. Coli was enhanced, and it polluted the feed, drinking water and field, and then passed to the healthy rabbits through the digestive tract.

(3) bad feeding and management, climate and other stress factors can promote the occurrence of the disease.

The autopsy findings of colibacillosis in rabbits:

(1) small punctate necrosis, gallbladder dilatation and mucosal edema were found in the liver and heart.

(2) the whole gastrointestinal tract has catarrhal inflammation, intestinal congestion, bleeding in different degrees, more gas. The gastric wall was edematous, the colon was dilated, the walls of colon and ileum were gray-white, and there were a lot of thick colorless gelatinous substance in the lumen, especially in the colon.
