CHARACTERIZATION OF EIGHT ANHUI ISOLATES OF RIEMERELLA ANATIPESTIFER
摘要
Abstract
Riemerella anatipestifer(RA)is the causative agent of some epizootic diseases in poultry. In this study, the biological characteristics of 8 RA strains isolated from Anhui in 2017 were studied.The serotyping showed that 6 isolates belonged to serotype 10 and other two isolates belonged to serotype 15.The testing of drug susceptibilities using 24 antibiotics revealed that the RA isolates were sensitive to amoxicillin, ceftazidime and cefpyridine but resistant to lomefloxacin and azithromycin. Biofilm formation assay showed that 7 isolates produced strong biofilm while only one strain(AH-35)was weak in vitro.The mRNA levels of 5 genes associated with RA biofilm formation was analyzed between AH-1 (strong biofilm formation strain) and AH35 (weak biofilm formation strain) by real-time PCR.The results showed that Riean_0023,Riean_1039 and Riean_1564 were significantly increased(p<0.01)in the AH-1 compared with AH-35.This study will benefit to the prevention and control of RA in Anhui province.关键词
