一例血管瘤型禽白血病的诊断

摘要

The lab diagnosis has been conducted for the affected chickens from a farm using histopathological method.The pathology were observed in tissue slides of swollen liver and kidney. The DNA samples were extracted for that detected against long terminal re-peat (LTR) gene by nested PCR method in one tube. It was demonstrated that this disease was hemangioma caused by ectogenic avian leukosis virus.%采用病理组织学方法对某养殖户发病死亡鸡进行观察，在肝、肾观察到大量红细胞和组织细胞病变；提取发病鸡DNA样本，以单管巢式PCR方法检测外源性禽白血病病毒长末端重复序列（LTR），扩增出一条预期长度带，证实该次疫病为外源性禽白血病病毒引发的血管瘤型禽白血病。
