摘要: 本试验选择临床症状明显、经禽白血病抗原检测为阳性的15只祖代清远麻鸡,采集肝脏、脾脏、肾脏等器官进行病理组织学观察和PCR诊断。结果显示,从病理组织切片中观察到肝脏、肾脏、脾脏、骨髓、腺胃、心脏、肺脏、胰腺和卵巢等组织中有大量的淋巴母细胞呈灶状增生或散在分布,以及少量的成髓细胞增生。禽白血病病毒主要侵害祖代清远麻鸡机体的内脏器官和骨髓,对大脑等神经组织损害较轻;PCR扩增结果表明,所采集的15份样品均能扩增出545 bp左右的特异性片段,证明15份组织样品中均存在J亚型禽白血病病毒。

Abstract: 15 Qingyuan MA chickens which appeared obviously clinical symptom and were tested to be avian leukosis positive were selected. The tumor organs, such as liver, spleen, kidney and so on, were carried on histopathology and PCR diagnosis. The pathology tissue slices from organs of liver, kidney, spleen, marrow, gland stomach, heart, lung, pancreatic gland ovary and so on, were observed, results showed that the proliferation of massive lymphoblasts or scatter and of small lymphomyelocytes were observed. The PCR identification indicated that all 15 samples can amplify a fragment about a length of 545 bp, which consisted with the expected size. The results suggested that all 15 isolates were the ALV-J avian Leukosis viruses.

Key words: Qingyuan MA chicken; avian leukosis; histopathology; PCR
