Injured and normal livers from broiler chickens sent to slaughter plants were collected for bacterial examination. A total of 223 macroscopically abnormal livers and 50 normal livers were received. Forty-seven thermophilic Campylobacter isolates were obtained from the livers with necrotic lesions; 39 isolates were identified as Campylobacter jejuni and eight as C. coli. In normal livers, six C. jejuni isolates were obtained. C. jejuni biotype 2 was the most common isolate recovered from injured livers, and C. jejuni biotype 1 was the most frequent isolate found in normal livers. On some occasions, Campylobacter spp. could be isolated from both the liver parenchyma and bile of the same bird. Results indicated that different species and biotypes of Campylobacter can be found in the livers of broiler chickens with and without lesions of necrotic hepatitis.
收集送往屠宰场的肉鸡受伤肝脏和正常肝脏进行细菌检测。共收到223个宏观上异常的肝脏和50个正常肝脏。从有坏死病变的肝脏中获得了47株嗜热弯曲菌分离株；39株分离株鉴定为空肠弯曲菌，8株为大肠弯曲菌。在正常肝脏中，获得了6株空肠弯曲菌分离株。空肠弯曲菌生物2型是从受伤肝脏中分离出的最常见菌株，空肠弯曲菌生物1型是在正常肝脏中发现的最常见菌株。在某些情况下，同一禽类的肝实质和胆汁中均可分离出弯曲菌属。结果表明，在有和没有坏死性肝炎病变的肉鸡肝脏中均可发现不同种类和生物型的弯曲菌。
