Gastrointestinal carriage of antimicrobial-resistant bacteria, especially carbapenemase-producing Enterobacterales (CPE), presents a critical public health threat globally. However, in many resource-constrained countries, epidemiological data on CPE is limited. Here, we assessed gastrointestinal carriage and associated factors of CPE among inpatient and outpatient children (≤ 5 years).

This study investigated the potential role of phages in the dissemination of antimicrobial resistance genes (ARGs) and virulence factor genes (VFGs) in Escherichia coli (E. coli). A comprehensive in silico analysis of 18,410 phage sequences retrieved from the National Center for Biotechnology Information database (NCBI) revealed distinct carriage patterns for ARGs and VFGs between lytic, temperate, and chronic phage types.

Peri-urban environments, characterized by dense human populations, cohabiting livestock, and complex food systems, serve as hotspots for food contamination and infectious diseases. Children aged 6-24 months are particularly vulnerable as they often encounter contaminated food and water, increasing their risk of food-borne disease, with diarrhea being a common symptom. We investigated the prevalence of antimicrobial resistance (AMR) in pathogenic Escherichia coli from 6-24 months-old children, their food, and cohabiting livestock, in Dagoretti South subcounty in Nairobi, Kenya.

Background: Active screening programs and early detection of asymptomatic carriers are effective in preventing carbapenem-resistant Acinetobacter baumannii (CRAB) dissemination in healthcare facilities. This study aims to identify risk factors associated with CRAB carriage among patients upon admission to an acute care hospital.

Methods: A case-case-control study was conducted at an acute care hospital.

Background: The impact of community carriage on the influx of extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-E) into hospitals remains understudied. In this prospective 2-year single-centre study, we investigate the community ESBL-E influx and trace the colonisation, nosocomial acquisition, transmission, and infection dynamics of ESBL-producing Escherichia coli (ESBL-Ec) in non-ICU wards at a tertiary care hospital.

Methods: This study reports primary and post hoc outcomes of the clinical trial NCT01208519 in which hospitalised patients were screened for rectal carriage of ESBL-E.
