摘要
某养殖户送来10只疑似脑脊髓炎的17日龄病鸡。经询问此鸡群共5100只,2日龄开始发病,2~3日龄少数死亡,6~7日龄死亡增多,每天死亡20只左右,到12日龄死亡更多,每天死亡100只左右。临床症状表现为:共济失调,头颈震颤,头上下扭曲,打转。为了进一步确诊和提供更有效的防治方法,笔者对该病例鸡进行了剖检,并采取病料,采用血清学、病理学等诊断方法。结合发病日龄、临床症状、病理变化、ELISA检测等,综合诊断为脑脊髓炎。
One chicken farmer sent me ten diseased chickens of 17-day old. I was told there are altogether 5,100 chickens in the farm. The disease occurred from 2 days old. A few died on the third day. Death of chickens increased during 6 to 7 days period. About 20 died each day. More chickens died among the 12-day old, with about 100 each day. The clinical signs are: progressive ataxia to paralysis, tremor of the head and neck, legs sitting on hocks and falling onto its side, and chirming. In order to further confirm and find out more efficient cure methods, the author anatomized chickens of this case, and applied methods of specimen, serology, and pathology, etc. Considering factors of dates of disease, clinical signs, pathological changes, and ELISA tests, the author diagnosed that the blood serum sample from delivered chickens are avian encephalomyelitis.
