科研动态

为了解鸡群中I群禽腺病毒（FAdV-I）的流行现状，从山东、黑龙江、吉林等地部分大规模养鸡场采集病料，进行病毒分离、PCR鉴定及同源性分析。结果显示：从76份病料中分离到10株FAdV-I，分离率为13%；10株FAdV-I中，1株为血清4型，6株为血清8b型，1株为血清9型，2株为血清11型。结果表明，山东、黑龙江、吉林等地均存在一定的FAdV-I流行，主要流行血清型已由4型转变为8b型，因此需要评估当前的4型灭活苗能否有效防控这些地区的FAdV-I流行。

Isolation and Identificationand Homology Analysis on Group I Fowl Adenovirus

In order to recognize the prevalence ofgroup I fowl adenovirus（FAdV-I）in poultry，samples were collected from several large-scalechicken farms in Shandong，Heilongjiang and Jilin provinces for FAdV isolation，PCR assay and homology analysis. Resultsshowed that 10 FAdV-I strains were isolated from 76 samples with the positiverate reaching 13%. Among the 10 FAdV-I strains，1 of them belonged to serotype 4，6 of them belonged to serotype 8b，1 of them belonged to serotype 9，and 2 of them belonged to serotype 11. Theresults indicated that certain FAdV-I infection existed in Shandong，Heilongjiang and Jilin provinces，and the main serotypes had been transferredfrom serotype 4 to serotype 8b，thus the current serotype 4 inactivated vaccines need to be evaluatedto determine if they could control the spread of FAdV-I effectively.
