AI Article Synopsis

  • Nosocomial infections from ESBL-producing E. coli are a significant global health issue that requires urgent attention.
  • A gene cluster that includes the Clp ATPase ClpK was identified in Danish isolates, which may enhance bacterial survival.
  • This gene cluster provides thermoprotection, allowing the bacteria to withstand higher temperatures often found on medical devices in hospitals.

Article Abstract

Nosocomial infections caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli are a major concern worldwide. There is an urgent need to identify bacterial factors promoting survival and persistence of these organisms in the nosocomial environment. Here, we describe the presence of a gene cluster, containing the Clp ATPase ClpK, within a collection of Danish ESBL-producing E. coli isolates. The cluster conferred thermoprotection upon the isolates, and thus might facilitate survival on medical devices exposed to semi-high temperatures in a hospital setting.

DbChitI-3, Drosera binata's acidic chitinase, peaks at pH 2.5 from 15 °C to 30 °C. Gene expression is stimulated by polysaccharides and suppressed by monosaccharide digestion, implying a feedback loop in its transcriptional regulation.

Urinary tract infections (UTIs) are recognized as the second most common medical condition, following respiratory infections. Despite the availability of numerous efficacious antibiotics for the management of UTIs, the rising incidence of bacterial resistance presents significant challenges in the treatment of these infections. Bacteria are endowed with the ability to reproduce and develop resistance mechanisms against antibiotics.

Uropathogens, particularly bacteria, can infect any part of the urinary tract and cause bacteriuria. Our study aimed to examine the antibiotic-resistant profile, associated risk factors, and phenotypic and genotypic features of ESBL, carbapenemase, and mcr resistance genes in multidrug-resistant bacteria. Samples were inoculated on culture media, identified using standard biochemical tests, and species confirmation was performed via 16S rRNA gene amplification.

Background: Wild game meat has over the years gained popularity across the globe as it is considered a food source with high protein content, low fat content, and a balanced composition of fatty acids and minerals, which are requirements for a healthy diet. Despite this popularity, there is a concern over its safety as many species of wildlife are reservoirs of zoonotic diseases including those of bacterial origin, more so antibiotic-resistant bacteria.

Methods: This study aimed to describe the prevalence of antibiotic-resistant bacteria in mammalian wild game, following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines.
