后經臨床觀察，病理剖檢及實驗室檢驗等，確診為大腸桿菌病，后對癥治療，取得了良好效果，現報告如下：
After clinical observation, pathological examination and laboratory examination, diagnosed with Escherichia coli disease, symptomatic treatment, obtained favorable result, report as follows now:
  一、發病情況：該養殖戶飼養的是美系白色獺兔，9月20日發現有8只體重約3.5公斤的母兔發病，22日發病母兔增加到18只，發病率為種母兔飼養量的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，排出小而堅硬糞便，個別不排糞。
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。據實驗室涂片鏡檢，細菌學檢查結果，結合臨床表現及剖檢變化，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.
  藥敏試驗結果為：對慶大霉素、氯霉素、氟哌酸高敏，對卡那霉素、痢特靈、鏈霉素中敏，對四環素、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，死兔深埋，對兔舍進行有效清掃。火堿、百毒殺交替消毒。另外加強通風，保持兔籠干燥。用人工鹽5-6克，病情嚴重者用蓖麻油10-15毫升，加溫水人工灌服，同時肌注慶大霉素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。很多養殖戶在發現成年兔排出糞便小而堅硬時，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殖戶，在獺兔發生便秘時，應借助科學診斷方法，作出正確診斷，以防誤診，造成更大的經濟損失。
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.
