Genomic study of Acinetobacter baumannii strains co-harboring blaOXA-58 and blaNDM-1 reveals a large multidrug-resistant plasmid encoding these carbapenemases in Brazil

Frontiers in Microbiology
IntroductionAcinetobacter baumannii contributes significantly to the global issue of multidrug-resistant (MDR) nosocomial infections. Often, these strains demonstrate resistance to carbapenems (MDR-CRAB), the first-line treatment for infections ...

Genetic Diversity of Polymyxin Resistance Genes in Klebsiella pneumoniae Clinical Isolates

Molecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT This study investigates the genetic diversity and evolutionary mechanisms driving polymyxin resistance in Klebsiella pneumoniae, a critical priority pathogen. By analysing mgrB, phoPQ and pmrAB genes in susceptible (PM‐S) and resistant (PM‐R) populations through neutrality tests (Tajima D, Fu & Li's D) we uncovered polygenic adaptation and ...

To Ban or Not to Ban: The UK's Hamlet Moment With Farm Antibiotics

Politics &Policy, Volume 53, Issue 6, December 2025.
ABSTRACT This article applies the Multiple Streams Framework (MSF) to examine post‐Brexit antimicrobial resistance (AMR) governance in UK agriculture, focusing on the contested regulation of prophylactic antibiotic use in farm animals. The study reveals how Brexit created a structural policy window, yet political and ideological dynamics rendered it ...

An Equity‐Focused Systematic Analysis of Antimicrobial Resistance National Action Plans in 14 West African Countries

Tropical Medicine &International Health, Volume 30, Issue 12, Page 1295-1312, December 2025.
ABSTRACT Objectives Antimicrobial resistance is a growing global health threat that disproportionately affects socially and economically disadvantaged populations. National Action Plans are critical for coordinating national responses, but the extent to which they address equity remains unclear. This study assessed how antimicrobial resistance National

Evidence for Clonally Associated Increasing Rates of Azithromycin Resistant Neisseria gonorrhoeae in Rio de Janeiro, Brazil

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Azithromycin is one of the drugs used in the combined therapy for syndromic treatment of gonorrhoea in many countries, including Brazil. Our research group, which receives isolates from clinical laboratories since 2006, has detected, after 2016, a tendency of rising rates of azithromycin resistance, with isolates showing higher minimal inhibitory ...
