Natural Transformation of and Its Determinants.

In a previous study, it was shown that , a member of , is naturally competent. However, whether natural competence is universal in remains unknown. In this study, it was shown for the first time that was naturally competent in the laboratory condition; however, was not naturally competent under the same conditions.

The functional identification of Dps in oxidative stress resistance and virulence of Riemerella anatipestifer CH-1 using a new unmarked gene deletion strategy.

Excessive iron in the bacterial cytoplasm can potentiate the production of harmful reactive oxygen species (ROS). Riemerella anatipestifer (R. anatipestifer, RA), a gram-negative bacterium, encodes an iron uptake system, but its iron detoxification mechanism is unknown.

Role of LptD in Resistance to Glutaraldehyde and Pathogenicity in .

is a gram-negative bacterium that causes disease in ducks and other birds. Despite being an important pathogen in poultry, the pathogenesis and drug resistance mechanisms of this bacterium are poorly understood. An analysis of our unpublished RNA-Seq data showed that , a gene encoding one of the lipopolysaccharide transport components, is transcribed at higher levels in strain CH-1 than in strain ATCC11845.

New Perspectives on Galleria mellonella Larvae as a Host Model Using Riemerella anatipestifer as a Proof of Concept.

larvae have been used as a host model to study interactions between pathogens and hosts for several years. However, whether the model is useful to interrogate infection biology remained unknown. This study aimed to exploit the potential of larvae and reveal their limitations as a host model for infection.
