后經(jīng)臨床觀察,病理剖檢及實(shí)驗(yàn)室檢驗(yàn)等,確診為大腸桿菌病,后對(duì)癥,取得了良好效果,現(xiàn)報(bào)告如下:
After clinical observation, pathological examination and laboratory examination, diagnosed with Escherichia coli disease, symptomatic treatment, obtained favorable result, report as follows now:
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%.
One, the incidence: the farmers rearing is the United States Department of White Rex Rabbit, September 20th found a female rabbit in 8 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 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. Rabbit haemorrhagic disease, depression, loss of appetite or waste vast, discharge of small hard stool, the individual does not defecation.
三、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,其他器官無明顯變化。
Three, necropsy. Necropsy 3 died of rabbit intestinal mucosa, with different degrees of bleeding, swelling and mesenteric lymph nodes, ileum and cecum and ileocecal mucosa also have different degrees of swelling, no significant changes in other organs.
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。
Four, diagnosis. According to laboratory smear, bacteriological examination results, combined with the clinical manifestations and pathological change, diagnosis of rabbit Escherichia coli infection.
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。
The drug sensitivity test of gentamicin, chloramphenicol, norfloxacin: Gao Min, kanamycin, streptomycin, furazolidone in sensitivity, is not sensitive to penicillin, tetracycline, 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?;饓A、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。
Five, prevention measures. The disease of rabbit isolated rearing, died buried on the rabbit rabbit, thorough cleaning. Caustic soda, alternative disinfection baidusha. In addition to strengthen ventilation, keep the rabbit hutch drying. Artificial salt 5-6 grams, serious illness with castor oil 10-15 ml warm water, artificial perfusion and intramuscular injection of gentamicin, 20000 units / kg body weight, 2 times a day. Add norfloxacin in feed, connect to use 4-6 days. The rabbit population is stable, the group inoculated Escherichia coli inactivated vaccine 2 ml / only.
六、小結(jié)。很多養(yǎng)殖戶在發(fā)現(xiàn)成年兔排出糞便小而堅(jiān)硬時(shí),只考慮是由于喂精料過多,青飼料不足,缺水等原因引起的便秘,而忽視了大腸桿菌作梗。所以筆者敬告廣大養(yǎng)殖戶,在獺兔發(fā)生便秘時(shí),應(yīng)借助科學(xué)診斷方法,作出正確診斷,以防誤診,造成更大的經(jīng)濟(jì)損失。
Six, summary. Many farmers found in adult rabbit feces are small and hard, considering only due to feed too much, forage shortage, water shortage and other reasons caused by constipation, while ignoring the Escherichia coli obstruct. So I advise the farmers, in Rex Rabbit constipation, should use scientific method of diagnosis, diagnosis, to prevent misdiagnosis, resulting in greater economic losses.
