Molecular Epidemiology and Antibiotic Resistance Associated with <i>Avian Pathogenic Escherichia coli</i> in Shanxi Province, China, from 2021 to 2023.

ABSTRACT: Avian Pathogenic Escherichia coli (APEC) constitutes a major etiological agent of avian colibacillosis, which significantly hinders the development of the poultry industry. Conducting molecular epidemiological studies of APEC plays a crucial role in its prevention and control. This study aims to elucidate the molecular epidemiological characteristics of Avian Pathogenic Escherichia coli in Shanxi Province. In this study, 135 APEC strains were isolated and identified from 150 liver samples of diseased and deceased chickens exhibiting clinical symptoms, which were collected from farms in Shanxi Province between 2021 and 2023. The isolates were then analyzed for phylogenetic clustering, drug resistance, resistance genes, virulence genes, and biofilm formation capabilities. The r
