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 ...

On the Difficulty to Detect Carbapenem Resistance in the Environment: Characterisation of Escherichia coli With Reduced Carbapenem Susceptibility Isolated in a French River

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
We characterised E. coli strains with reduced carbapenem susceptibility isolated from a rural watershed. Of the 863 isolates collected on ChromID Carba medium, E. coli identification was confirmed for only 7 isolates, 6 of which show reduced susceptibility to carbapenems.

Antibiotic‐Induced Dysbiosis of the Gut Microbiota Shifts Host Tryptophan Metabolism and Increases the Susceptibility of Mice to Pulmonary Infection With Pseudomonas aeruginosa

Immunology, Volume 175, Issue 4, Page 453-466, August 2025.
Antibiotic‐induced dysbiosis of the gut microbiota shifts host tryptophan metabolism and impairs the innate immune response during Pseudomonas aeruginosa pulmonary infection. (A) Eubiosis: During eubiosis, the intestinal microbiota metabolises tryptophan into indole metabolites, which keeps tryptophan levels within normal serum concentrations. However,

Distribution of Carbapenemase Genes Associated With Global High‐Risk Sequence Types in Pseudomonas aeruginosa Isolates From Chronic Leg Ulcer Patients in Northern Tanzania

International Wound Journal, Volume 22, Issue 8, August 2025.
ABSTRACT Carbapenem‐resistant Pseudomonas aeruginosa exacerbates the healing of chronic leg ulcer among patients. Further, production and dissemination of the carbapenemase genes are associated with P. aeruginosa high‐risk sequence types. Hence, understanding the population structure of these organisms is essential for healthcare personnel to establish
