Determinants of Antimicrobial Resistance in Acinetobacter baumannii Isolates From Intensive Care Patients in Latvia

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Background Acinetobacter baumannii is a leading nosocomial pathogen in intensive care units (ICUs), often resistant to multiple antibiotics. Data from the Baltic region remain scarce, limiting infection control and stewardship strategies. Methods We conducted an integrated phenotypic–genotypic analysis of A.

High carriage of plasmid-mediated quinolone resistance (PMQR) genes by ESBL-producing and fluoroquinolone-resistant Escherichia coli recovered from animal waste dumps

Molecular Biology Reports, 2023
Abstract There have been a rapid rise in the consumption of quinolones in human and veterinary medicine recently. This has contributed in no small measure to the rising incidence of quinolone resistance in bacteria. This study investigated the antibiotic resistance and carriage of plasmid-mediated quinolone resistance (PMQR) determinants by ...

Genotypic Profiling of Virulence and Antibiotic Resistance Genes of Escherichia coli Isolates Derived From Bovine Milk in the Dr. Kenneth Kaunda District, South Africa

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
The growing threat of antimicrobial resistance (AMR) among foodborne pathogens poses a significant public health risk in South Africa, largely driven by excessive antibiotic use in dairy farming practices. This study investigated the virulence and AMR profiles of Escherichia coli isolated from bovine quarter milk samples in the Dr.

Biofilm Formation and Antibiotic Resistance Genes of Escherichia coli From Poultry Farms and Clinical Samples

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Three clinical isolates, including EPEC, EAEC and ETEC, were identified as pathogenic strains. All isolates were biofilm producers, and 96.4% of poultry isolates had strong biofilm formation capacity. The highest rates of resistance were recorded against tylosin (100%), neomycin (92.85%), tetracycline (85.7%), ampicillin (73.8%), doxycycline (71.4 ...

Unveiling the Genetic Diversity and Antimicrobial Resistance Profiles of Salmonella Population From 2016 to 2020 in Thai Canal Water

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
By employing whole genome sequencing to analyse 351 Salmonella genomes isolated between 2016 and 2020, the characteristics and antimicrobial resistance properties of Salmonella enterica found in Bangkok canals were elucidated. Among studied isolates, 39.0% were potentially multidrug‐resistant, and STs 34 and 213 found might have circulated between ...
