摘要
为了解徐州地区鸡群白血病的感染情况,从2013年3月到2013年12月在徐州部分地区的鸡场随机采样500份,通过酶联免疫吸附试验(ELISA)检测gp27抗原阳性率以及J亚型白血病(ALV-J)和AB亚型白血病(ALV-AB)的抗体阳性率。调查显示,徐州大多数鸡场均存在白血病的感染,其中ALV-J为阳性的鸡场有8所,ALV-J最高阳性率达28.6%,ALV-AB最高阳性率为23.3%,ALV-AB感染的年龄段存在一定差异,感染率最高的年龄段是75周龄;肉鸡ALV-J、ALV-AB感染率较高,蛋鸡也存在ALV-J感染的情况,说明ALV-J的宿主范围正在扩大。
The research aimed to further study the infection virus of chicken in xuzhou some areas in xuzhou from immunosorbent assay （ELISA） 500 serum samples were randomly March of 2013 to December of ,the antigen positive rate of gp27 subtype and AB subtype of avian leukemia were detected. The conditions of collected from 2013. Using avian leukemia chicken farm of enzyme -linked ,the antibody positive rate of J infection of leukemia was found in most farms of xuzhou.There were 8 ALV-J positive farms.The highest positive rate of ALV-J was 28.6% and the highest positive rate of ALV-AB was 23.3% .There was some difference in the infection of ALV-J and ALV-AB in different ages ,the highest infection rate appeared in 75 week. the infected of ALV-J also existed in laying hens.These results indicated that the host range of ALV-J was expanding further in recent years.
