Diversity of Gene Cassette Promoters in Class 1 Integrons from Wastewater Environments [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT The diversity of gene cassette promoters in class 1 integrons was investigated in 47 strains isolated from wastewaters. The weak PcW and PcH1 variants predominated, suggesting that, similar to clinical environments, high rates of gene cassette recombination, rather than high expression of gene cassettes, have been preferentially ...

Highly Resolved Community Sewage Metagenomics Unveiling Landscape and Transmission Patterns of Antibiotic Resistome in Hong Kong Populations

Advanced Science, Volume 13, Issue 20, 9 April 2026.
A large‐scale, high‐resolution antimicrobial resistance (AMR) surveillance in Hong Kong community sewage combining short‐ and long‐read sequencing. The resistome profile is comprehensively characterized, and this upstream sampling strategy demonstrated superiority in reflecting the human gut resistome.

Imported Retail Beef and Chicken Meat Products Serve as Reservoirs for Emerging Antibiotic‐Resistant Pathotypes of Escherichia coli in Pristine Areas Free From Agricultural Activity

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Retail meat–derived E. coli frequently harbored multidrug‑resistance phenotypes, diverse virulence determinants, and plasmid‑encoded resistance genes with high conjugative potential. Results indicate meat and poultry as underrecognized reservoirs facilitating dissemination of antimicrobial resistance and pathogenic lineages, with imported products ...
