Genomic analysis and experimental pathogenic characterization of Riemerella anatipestifer isolates from chickens in China
ABSTRACT: Waterfowl have a high likelihood of being infected with Riemerella anatipestifer. Although the pathogen is found in domestic ducks, turkeys, geese, and wild birds, there is little information available about the consequences of infection during egg laying and hatching in chickens. Here, we...

| description | ABSTRACT: Waterfowl have a high likelihood of being infected with Riemerella anatipestifer. Although the pathogen is found in domestic ducks, turkeys, geese, and wild birds, there is little information available about the consequences of infection during egg laying and hatching in chickens. Here, we present the first report of a novel sequence type of R. anatipestifer S63 isolated from chickens in China. On the basis of pan-genome analysis, we showed S63′s genome occupies a distinct branch with other R. anatipestifer isolates from other hosts. Galleria mellonella larval tests indicated that S63 is less virulent than R. anatipestifer Ra36 isolated from ducks. Ducks and hens are susceptible to S63 infection. There is no mortality rate for chickens or ducks, but adult chickens experience neurological symptoms that reduce egg production and hatching rates. In chickens, S63 might be passed vertically from parents to offspring, resulting in ''jelly-like'' lifeless embryos. Using quantitative PCR, S63 was detected in the brain, liver, reproductive organs, and embryos. As far as we know, this is the first report of R. anatipestifer in hens, a disease that can reduce egg productivity, lower hatching rates, and produce jelly-like lifeless embryos, and the first report to raise the possibility that hens can be infected by roosters via semen. |
