| Abstract: | In order to understand the latest prevalence of Mycoplasma synoviae(MS)infection in China,samples were collected from chicken farms suspected of infecting MS in 8 provinces including Jiangsu,Anhui,Shandong,Henan,Hebei,Ningxia,Heilongjiang and Hubei during 2016 to 2019 for the isolation and identification of MS strains.A total of 48 MS isolates were obtained.Sequencing and phylogenetic analysis of the vlhA gene of these isolates showed that 46 of them belonged to the K genotype,and the other 2 belonged to the A genotype and E genotype,respectively.These results showed that the prevailing dominant genotype in China was K genotype,which was significantly different from the prevailing genotype in other countries and regions.The results of this study provide the necessary epidemiological basis for formulating strategies suitable for the control and eradication of MS in chickens flocks in China. |
