Genomic Characterization of Salmonella enterica Resistant to Cephalosporin, Quinolones, And Macrolides
This study focused on determining the antimicrobial resistance of 373 Salmonella isolates, collected from various foods, humans, and animals, as well as the environmental sludge between 2005 and 2020 in Türkiye. Phenotypic analysis of the resistance was determined by disk diffusion method. Isolates resistant to any of the following: ciprofloxacin, pefloxacin, azithromycin, and ceftriaxone were tested for the presence of quinolone, beta-lactamase, and/or macrolide resistance genes by PCR and gel electrophoresis. Five multi-drug-resistant isolates were then further whole genome sequenced and analyzed. More than 32% (n = 120...

Poultry production as the main reservoir of ciprofloxacin- and tigecycline-resistant extended-spectrum β-lactamase (ESBL)-producing < em > Salmonella enterica < /em > serovar Kentucky ST198.2-2 causing human infections in China
In this study, whole-genome sequencing (WGS) analysis divided 327 S. Kentucky ST198 isolates into two clades, of which ST198.2 is more prevalent than ST198.1 worldwide. We further compared the genomic characteristics of 70 ST198 isolates from animals and humans during 2019-2022 plus previously reported 38 isolates from 2013 to 2019 in China. One hundred five of the 108 isolates were ST198.2, which could be differentiated into two subclades. ST198.2-1 was prevalent in isolates during 2013-2019, while ST198.2-2 has increased to be the predominant subclade in isolates since 2019. CRISPR typing can differentiate the clade ST19...

Effects of antibiotic-induced resistance on the growth, survival ability and virulence of Salmonella enterica
In this study, eight antibiotic-sensitive S. enterica strains were induced by Ampicillin (Amp) and Ciprofloxacin (CIP), respectively, and AMP-resistant and CIP-resistant mutants were obtained. The growth characteristics under different temperatures (25, 30, 35 °C), viability after exposure to heat (55, 57.5, 60 °C) and acid (HCl, pH = 3.0), the virulence potential (adhesion and invasion to Caco-2 cells, biofilm formation and motility) and the lethality in a model species (Galleria mellonella) were evaluated and compared for S. enterica strains before and after antibiotic exposure. The induction by AMP and CIP are likely ...
