Prevalence, antimicrobial resistance and phylogenetic analysis of contamination and transmission in yellow-feathered broiler hatcheries in China.

is a significant avian pathogen causing infectious diseases in poultry, with hatching playing a crucial role in its transmission. Despite its importance, systematic research on transmission in hatcheries remains limited. This study evaluates the prevalence and antimicrobial resistance of throughout all production stages in yellow-feathered broiler hatcheries: laying, egg storage, incubating, hatching, and post-hatch.

Increased Drug Resistance and Biofilm Formation Ability in ST34-Type Typhimurium Exhibiting Multicellular Behavior in China.

Typhimurium is an important food-borne pathogen. In this paper, multicellular behavior and associated characteristics of Typhimurium isolated from human and animal source food were studied. All the Typhimurium strains exhibiting multicellular behavior (100%) belonged to the ST34 type.
