后经临床观察，病理剖检及实验室检验等，确诊为大肠杆菌病，后对症，取得了良好效果，现报告如下：
After clinical observation, pathological examination and laboratory examination, diagnosed with Escherichia coli disease, symptomatic treatment, obtained favorable result, report as follows now:
  一、发病情况：该养殖户饲养的是美系白色獭兔，9月20日发现有8只体重约3.5公斤的母兔发病，22日发病母兔增加到18只，发病率为种母兔饲养量的38%,23日已有3只死亡，死亡率为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、临床症状。病兔精神沉郁，食欲减少或废绝，排出小而坚硬粪便，个别不排粪。
Two, clinical symptoms. Rabbit haemorrhagic disease, depression, loss of appetite or waste vast, discharge of small hard stool, the individual does not defecation.
  三、剖检变化。剖检3只病死兔，肠粘膜有不同程度出血，肠系膜淋巴结肿胀，回肠和盲肠粘膜以及回盲瓣也有不同程度肿胀，其他器官无明显变化。

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、诊断。据实验室涂片镜检，细菌学检查结果，结合临床表现及剖检变化，确诊为兔大肠杆菌感染。
Four, diagnosis. According to laboratory smear, bacteriological examination results, combined with the clinical manifestations and pathological change, diagnosis of rabbit Escherichia coli infection.
  药敏试验结果为：对庆大霉素、氯霉素、氟哌酸高敏，对卡那霉素、痢特灵、链霉素中敏，对四环素、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。将病兔隔离饲养，死兔深埋，对兔舍进行彻底清扫。火碱、百毒杀交替。另外加强通风，保持兔笼干燥。用人工盐5-6克，病情严重者用蓖麻油10-15毫升，加温水人工灌服，同时肌注庆大霉素2万单位/公斤体重，每天2次。饲料中加入氟哌酸，连用4-6天。兔群稳定后，全群接种大肠杆菌灭活疫苗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、小结。很多养殖户在发现成年兔排出粪便小而坚硬时，只考虑是由于喂精料过多，青饲料不足，缺水等原因引起的便秘，而忽视了大肠杆菌作梗。所以笔者敬告广大养殖户，在獭兔发生便秘时，应借助科学诊断方法，作出正确诊断，以防误诊，造成更大的经济损失。
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.
