Antimicrobial resistance of <i>Escherichia coli</i> from broilers in large-scale poultry farms in Shandong Province.

ABSTRACT:

Background

Antimicrobial resistance (AMR) is a global challenge affecting both healthcare and agricultural fields, as emphasized by the World Health Organization (WHO). Industrial poultry production plays a crucial role in the development and dissemination of AMR. A comprehensive understanding of the molecular mechanisms underlying AMR is imperative for developing effective control strategies.

Materials and methods

This study aimed to identify factors influencing AMR in Escherichia coli from large-scale commercial broiler farms. Samples, including 371 anal swabs, 95 fecal swabs, and 122 feed-trough swabs, were collected from Cobb broilers at the four production stages (1, 15, 26, and 38 days of age) on typical farms in Shandong Province. From these specimens, 508 E
