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 ...

A Pilot Study on the Prevalence and Characterization of Multidrug‐Resistant Gram‐Negative Bacteria in Chicken and Pork Meat Around Kathmandu District, Nepal

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
This study investigated multidrug resistance in Gram‐negative bacteria from chicken and pork meat in Kathmandu, isolating 136 strains from 13 samples. Nearly half were multidrug resistant, highlighting contaminated meat as a potential route for zoonotic transmission and the need for antimicrobial resistance monitoring in Nepal.

Using Selective Agar Containing Ciprofloxacin and Tetracycline Reveals Resistant Oral Microbiota in Healthy and Periodontitis Patients

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
Oral biofilms from healthy and periodontitis patients harbor diverse bacteria, including aerobes and obligate anaerobes. Using selective media with tetracycline or ciprofloxacin, 495 strains (106 species) were isolated. Resistance was common—32.9% to ciprofloxacin, 15.2% to tetracycline, 0.6% to ampicillin—highlighting the oral cavity as a reservoir ...

Genetic markers associated with resistance to beta-lactam and quinolone antimicrobials in non-typhoidal Salmonella isolates from humans and animals in central Ethiopia

Antimicrobial Resistance and Infection Control, 2017
Background Beta-lactam and quinolone antimicrobials are commonly used for treatment of infections caused by non-typhoidal Salmonella (NTS) and other pathogens. Resistance to these classes of antimicrobials has increased significantly in the recent years.

Global Analysis of the Co‐Occurrence of Antimicrobial and Metal Resistance Genes in Bacterial Genomes From Dairy‐Isolated Pathogens

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Metal contamination in dairy systems drives antibiotic resistance through co‐selection. Analysis of 3303 genomes revealed 74% of isolates harbour more metal than AMR genes. Arsenic (arsB) and tetracycline (tet(38)) resistance co‐occur in 43% of bacteria, exhibiting nearly identical prevalence, suggesting a tight genetic linkage.
