摘要:
为了解J亚群禽白血病病毒(ALV-J) 及其与禽网状内皮细胞增生症病毒(REV)、马立克氏病病毒(MDV)和鸡传染性贫血病病毒(CAV)的混合感染现象,本研究从宁夏、湖北、广东、山东、辽宁、吉林、黑龙江7个省的39个蛋鸡群收集临床表现和剖检病理变化疑似禽白血病的病料样品184份,采用PCR、病毒分离和IFA检测样品中ALV-J、REV、MDV和CAV。结果表明,7个省蛋鸡场均存在ALV-J感染,病料样品阳性率为60.9 %,检测鸡群阳性率为82.1 %,与REV、MDV、CAV的混合感染率分别为13.6 %、24.5 %、22.8 %,其中存在较为严重的双重感染(29.0 %)和3重感染(18.8 %),甚至4重感染(1.7 %)。研究结果表明,我国蛋鸡群中普遍存在ALV-J感染,而且与REV、MDV、CAV混合感染严重;提示ALV-J已经可以引起蛋鸡群发病,在临床诊断和致病性研究中,应考虑到多重感染的影响。
Abstract:
To investigate the co-infection status of avian leukaemia viruses (ALV) in layer flocks in China, 184 samples were collected from suspected ALV-J infection cases in Ningxia, Hubei, Guangdong, Shandong, Liaoning, Jilin and Heilongjiang provinces. These samples were subjected to PCR, virus isolation and indirect immunofluorescence assay (IFA) to detect infection by subgroup J ALV (ALV-J) in layer chicken flocks and co-infection with Reticuloendotheliosis (REV), Marek’s disease virus (MDV) or Chicken anemia virus (CAV). The results showed that infection of ALV-J exists in all seven provinces with 60.9 % samples detected positive in 82.1 % flocks. The co-infection with REV, MDV or CAV with ALV-J accounted for 13.6 %, 24.5 %,22.8 %, respectively. Multiple infection by up to 4 different viruses was detected in some cases. These results indicated there was serious ALV-J infecton in layer flocks in China and co-infection with other immunosuppressive virus is prevalent, therefore it is strongly recommended more attention be paid on co-infection in clinical diagnosis of ALV-J infection in layer flocks in the future.
