AI Article Synopsis

  • Genes for three types of beta-lactamases (CMY-2, CTX-M-14, SHV-12) were found in 3 out of 5 E. coli isolates from healthy chickens, indicating resistance to certain antibiotics.
  • The isolates were identified from fecal samples, highlighting antibiotic resistance in farm animals.
  • Two remaining isolates had a mutation in the promoter region of the ampC gene, which could also contribute to antibiotic resistance.

Article Abstract

Genes encoding the CMY-2, CTX-M-14, and SHV-12 beta-lactamases were detected in three of five Escherichia coli isolates from fecal samples from healthy chickens which showed resistance or diminished susceptibility to extended-spectrum cephalosporins. A -42 mutation at the promoter region of the ampC gene was detected in the other two isolates.

The aim of the present work was to genetically characterise cefotaxime-resistant enterobacteria isolated from community carriers in Bulgaria. In total, 717 faecal samples from children and adults in five medical centres in Sofia, Pleven and Burgas were examined. Antimicrobial susceptibility was evaluated by the disk diffusion method.

  • * Analysis showed that Salmonella isolation rates were low (0.070%) but revealed shifting dominant serotypes over the years and notable resistance patterns, particularly against streptomycin and tetracycline.
  • * The research identified mechanisms of antibiotic resistance, including the spread of resistance to Escherichia coli, raising concerns about the increasing incidence of cephalosporin-resistant Salmonella strains.

Extended-spectrum β-lactamases (ESBLs)-producing E. coli have been proposed as an indicator bacterium for antimicrobial resistance (AMR) surveillance within a OneHealth framework. However, it is important to understand the effects and potential biases ESBL-selection has on E.

In February 2023, sequence type (ST) 38 producing oxacillinase 244 (OXA-244-Ec ST38) was detected from three patients in a hospital in western Poland. Overall, OXA-244-Ec ST38 was detected from 38 colonised patients in 13 wards between February and June 2023. The outbreak was investigated on site by an infection control team, and the bacterial isolates were characterised microbiologically and by whole genome sequencing.

Article Synopsis
  • Extended-spectrum cephalosporins (ESCs) are crucial antimicrobials used to combat multidrug-resistant (MDR) bacterial infections, but resistance against them is rising, mainly due to certain β-lactamases produced by Enterobacterales.
  • This study focused on analyzing Escherichia coli strains with resistance genes collected from Canada, France, and Germany over a 14-year period, employing advanced sequencing techniques to examine the transmission of these resistance genes via plasmids.
  • Five distinct plasmid subtypes linked to the spread of ESC resistance genes were identified, with varying prevalence across geographic regions and host species, highlighting the role of plasmid diversity in the global issue of antibiotic resistance.
