Abstract
This study investigates the correlation between antimicrobial resistance and PFGE (Pulsed-Field Gel Electrophoresis) typing in Escherichia coli (E. coli) strains isolated from geese on four farms in Heilongjiang Province. A total of 109 isolates were subjected to antimicrobial susceptibility testing using the K-B paper diffusion method with 15 different antimicrobial agents. PFGE typing was then performed for further analysis. The results indicated that more than 70% of the isolates were resistant to ampicillin, amoxicillin, imipenem, tetracycline, and doxycycline. Observing the presence of multidrug resistance, with 92.66% of the strains exhibiting resistance to 6 to 9 drugs. Among the 12 most resistant isolates, eight distinct PFGE patterns were identified, with strain similarity coefficients ranging from 40% to 60%. These findings highlight the presence of complex drug-resistant genotypes among E. coli strains from geese across all four farms, each displaying varying levels of resistance.
期刊介绍:
First self-published in 1921, Poultry Science is an internationally renowned monthly journal, known as the authoritative source for a broad range of poultry information and high-caliber research. The journal plays a pivotal role in the dissemination of preeminent poultry-related knowledge across all disciplines. As of January 2020, Poultry Science will become an Open Access journal with no subscription charges, meaning authors who publish here can make their research immediately, permanently, and freely accessible worldwide while retaining copyright to their work. Papers submitted for publication after October 1, 2019 will be published as Open Access papers.
An international journal, Poultry Science publishes original papers, research notes, symposium papers, and reviews of basic science as applied to poultry. This authoritative source of poultry information is consistently ranked by ISI Impact Factor as one of the top 10 agriculture, dairy and animal science journals to deliver high-caliber research. Currently it is the highest-ranked (by Impact Factor and Eigenfactor) journal dedicated to publishing poultry research. Subject areas include breeding, genetics, education, production, management, environment, health, behavior, welfare, immunology, molecular biology, metabolism, nutrition, physiology, reproduction, processing, and products.
