Riemerella anatipestifer is reported worldwide as a cause of septicemic and exudative diseases of domestic ducks. In this study, we identified a mutant strain RA2640 by Tn4351 transposon mutagenesis, in which the AS87_04050 gene was inactivated by insertion of the transposon. Southern blot analysis indicated that only one insertion was found in the genome… (More)
Riemerella anatipestifer is a well-described pathogenic bacterium, which is reported worldwide as the cause of epizootic infectious polyserositis of waterfowl and other avian species. Here, we present the complete genome sequence of R. anatipestifer strain CH3, the serotype 1 prevalent in China.
Riemerella anatipestifer is an important pathogen of waterfowl, which causes septicemia anserum exsudativa in ducks. In this study, an AS87_03730 gene deletion R. anatipestifer mutant Yb2ΔAS87_03730 was constructed to investigate the role of AS87_03730 on R. anatipestifer virulence and gene regulation. By deleting a 708-bp fragment from AS87_03730, the… (More)
Riemerella anatipestifer is one of the most important bacterial pathogen of ducks and causes a contagious septicemia. R. anatipestifer infection causes serositis syndromes similar to other bacterial infections in ducks, including infection by Escherichia coli, Salmonella enterica and Pasteurella multocida. Clinically differentiating R. anatipestifer… (More)
