Genetic diversity, serotype, and antimicrobial profiles of Riemerella anatipestifer isolated from ducks and chickens in Thailand.

ABSTRACT: Riemerella anatipestifer, which causes New Duck Syndrome, poses a significant threat to poultry production, causesing respiratory distress, neurological signs, and septicemia primarily in ducks and occasionally chickens. R. anatipestifer outbreak control requires knowledge about their genetic diversity, serotypes, and antibiotic profiles, which are currently unavailable. In this study, R. anatipestifer was isolated from ducks and chickens in Thailand between 2021 and 2023 to characterize their genetic relatedness, antimicrobial profiles, and resistance genes. Seven different serotypes were identified in isolates from ducks. Non-typable strains were the most prevalent, followed by serotypes 7, 10, 1, 5, 11, and 17. However, only serotype 1 was identified in isolates from chickens. Antimicro
