        I群禽腺病毒的分離鑒定與同源性分析

        時間:2019-03-04   訪問量:1050

        為了解雞群中I群禽腺病毒(FAdV-I)的流行現(xiàn)狀,從山東、黑龍江、吉林等地部分大規(guī)模養(yǎng)雞場采集病料,進行病毒分離、PCR鑒定及同源性分析。結(jié)果顯示:從76份病料中分離到10FAdV-I,分離率為13%;10FAdV-I中,1株為血清4型,6株為血清8b型,1株為血清9型,2株為血清11型。結(jié)果表明,山東、黑龍江、吉林等地均存在一定的FAdV-I流行,主要流行血清型已由4型轉(zhuǎn)變?yōu)?/span>8b型,因此需要評估當前的4型滅活苗能否有效防控這些地區(qū)的FAdV-I流行。


        Isolation and Identificationand Homology Analysis on Group I Fowl Adenovirus

        In order to recognize the prevalence ofgroup I fowl adenovirusFAdV-Iin poultry,samples were collected from several large-scalechicken farms in ShandongHeilongjiang 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 strains1 of them belonged to serotype 4,6 of them belonged to serotype 8b,1 of them belonged to serotype 9and 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.
