Occurrence of multidrug resistance associated with extended-spectrum β‑lactamase and the biofilm forming ability of Escherichia coli in environmental swine husbandry.

December 2023
Extended-spectrum beta-lactamase (ESBL) production and biofilm formation are mechanisms employed by Escherichia coli to resist beta-lactam antibiotics. Thus, we aimed to examine antibiotic resistance associated with ESBL production and biofilm formation in E. coli isolates from swine farms in Southern Thailand.

- - Antimicrobial resistance (AMR) is a growing global health issue, primarily studied in livestock; this research focuses on AMR in sports animals like fighting cocks, bulls, and sport horses, as well as environmental soil samples.
- - The study isolated bacteria from feces of these animals and tested their resistance to 15 different antimicrobial agents while also examining various genetic factors related to virulence and AMR.
- - Results showed that fighting cocks exhibited the highest levels of AMR, with 62.5% of their isolates resistant to ampicillin, and they also had the highest rate of multidrug resistance compared to the other sports animals.
Article Synopsis
- Staphylococci, present as both harmless and harmful bacteria on skin and mucosa, were studied in sports animals in South Thailand, focusing on how antimicrobial use leads to antimicrobial resistance (AMR).
- A total of 122 animals were sampled, yielding 41 staphylococcal colonies and revealing high resistance rates, particularly 93% to penicillin and 51% to cephalosporin, with 56% identified as methicillin-resistant staphylococci (MRS).
- Notably, MRS from horses showed higher multidrug resistance compared to lower AMR rates in bulls and cocks, possibly due to different treatment preferences among animal owners.
Many studies have examined avian pathogenic Escherichia coli (APEC) from commercial broilers but few have examined isolates from native chickens. This study compared APEC isolates from commercial broilers and native chickens in regard to the phylogenetic group and the phenotypic and genotypic antimicrobial resistance profiles. From 100 suspect colibacillosis cases in both commercial broilers and native chickens, a total of 90 broiler isolates and 42 native chicken isolates were identified as E.
