Expanding the β‐Lactamase Family in the Human Microbiome

Advanced Science
β‐lactams, the most common antibiotics globally, have resistance primarily determined by β‐lactamases. Human microbiota and β‐lactams influence mutually; however, β‐lactamase variety and abundance in the human microbiome remain partially understood. This

Evolutionary and Epidemiological Characterization of Multidrug‐Resistant Escherichia coli Isolated From Pangolins in China

Integrative Zoology, EarlyView.
ABSTRACT Malayan pangolin populations have fallen to a critically endangered level, and illegal trafficking of wild pangolins is a global problem. Little is known about antimicrobial‐resistant bacteria (MDRB) harbored by pangolins, although pangolins are frequently consumed as food or used in traditional medicine. In this study, we report for the first

Spatial Patterns and Associated Factors of Intestinal Antibiotic Resistance Genes in Farmed Bullfrogs From Selected Farms Across Major Production Regions in China

Integrative Zoology, EarlyView.
Across selected bullfrog farms in major Chinese production regions, 106 intestinal ARG subtypes were detected, with tetracycline and sulfonamide resistance genes predominating and clear farm‐level variation. High‐risk ARGs, including ermB, floR, and qnrA, were associated with heavy metals, MGEs, and opportunistic pathogens. These findings highlight the

Structure-guided drug repurposing identifies aristospan as a potential inhibitor of β-lactamase: insights from virtual screening and molecular dynamics simulations

Frontiers in Pharmacology
The rise of β-Lactamase mediated antibiotic resistance is a major concern for public health; hence, there is an urgent need to find new treatment approaches.

Antimicrobial Resistance in Children With Bloodstream Infections: A Population‐Based Study in Stockholm, Sweden

Acta Paediatrica, EarlyView.
ABSTRACT Aim We retrospectively evaluated trends in antimicrobial resistance (AMR) in paediatric bloodstream infections and assessed changes in antimicrobial prescription patterns over a 20‐year period. Methods We analysed positive blood cultures from children admitted with suspected serious infection between 1998 and 2018.

Novel β-Lactamase bla _ARL in Staphylococcus arlettae [PDF]

, 2017
Penicillins are an important group of antibiotics used to treat various types of infections caused by Gram-positive bacteria. So far, the blaZ gene was the only known β-lactamase gene in staphylococci.

Carriage of antimicrobial‐resistant E. coli in urban stray cats (Felis catus)

Australian Veterinary Journal, EarlyView.
Antimicrobial resistance (AMR) in Escherichia coli is a growing concern in both human and veterinary medicine, driven by the inappropriate use of antimicrobials. Companion animals may act as community reservoirs and sentinels for antimicrobial‐resistant bacteria due to their close contact with humans and other animals.
