一、發(fā)病情況：該養(yǎng)殖戶飼養(yǎng)的是美系白色獺兔，9月20日發(fā)現(xiàn)有8只體重約3.5公斤的母兔發(fā)病，22日發(fā)病母兔增加到18只，發(fā)病率為種母兔飼養(yǎng)量的38%,23日已有3只死亡，死亡率為16%.
First, the incidence of the farmers rearing is the United States Department of White Rex, September 20th found that the incidence of 8 female rabbits only about 3.5 kg in weight, 22 day incidence of female rabbits increased to 18, the incidence rate of female rabbit rearing volume of 38%, 23, 3 rats died, the mortality was 16%.
二、臨床癥狀。病兔精神沉郁，食欲減少或廢絕，排出小而堅(jiān)硬糞便，個(gè)別不排糞。
Two. Clinical symptoms. The rabbits in the depression, loss of appetite or waste, discharge of small hard stool, defecation is not individual.
三、長(zhǎng)毛兔剖檢變化。剖檢3只病死兔，腸粘膜有不同程度出血，腸系膜淋巴結(jié)腫脹，回腸和盲腸粘膜以及回盲瓣也有不同程度腫脹，其他器官無(wú)明顯變化。
Three. Changes of necropsy in Angora rabbits. 3 rabbits died of intestinal bleeding, mesenteric lymph nodes swelling, ileum and cecum mucosa and ileocecal valve swelling in varying degrees, and other organs did not change significantly.
四、診斷。據(jù)實(shí)驗(yàn)室涂片鏡檢，細(xì)菌學(xué)檢查結(jié)果，結(jié)合臨床表現(xiàn)及剖檢變化，確診為兔大腸桿菌感染。藥敏試驗(yàn)結(jié)果為：對(duì)慶大霉素、氯霉素、氟哌酸高敏，對(duì)卡那霉素、痢特靈、鏈霉素中敏，對(duì)四環(huán)素、青霉素、磺胺嘧啶不敏感。
Four 、 diagnosis. According to the laboratory smear microscopy, bacteriological examination results, combined with clinical manifestations and necropsy changes, diagnosed as Escherichia coli infection in rabbits. The results of drug sensitivity test of gentamicin, chloramphenicol and norfloxacin on Gao Min, kanamycin, furazolidone, streptomycin sensitive, not sensitive to tetracycline, penicillin and sulfadiazine.
五、防治措施。將病兔隔離飼養(yǎng)，死兔深埋，對(duì)兔舍進(jìn)行徹底清掃。火堿、百毒殺交替。另外加強(qiáng)通風(fēng)，保持兔籠干燥。用人工鹽5-6克，病情嚴(yán)重者用蓖麻油10-15毫升，加溫水人工灌服，同時(shí)肌注慶大霉素2萬(wàn)單位/公斤體重，每天2次。飼料中加入氟哌酸，連用4-6天。兔群穩(wěn)定后，全群接種大腸桿菌滅活疫苗2毫升/只。

Many farmers found in adult rabbit feces are small and hard, only consider is due to feed too much, forage shortage, caused by shortages of constipation, neglect of Escherichia coli, so the author cautioned the majority of farmers in Angora rabbit constipation, should rely on science to make the correct diagnosis method.
