Background & Objective: The production of plasmid-mediated AmpC beta-lactamases (PMABLs) among urinary Klebsiella pneumoniae isolates causes a severe problem to the successful treatment of urinary tract infections (UTIs). This study was designed to evaluate antimicrobial resistance, the presence of AmpC beta-lactamase genes, and the genetic relatedness among K. pneumoniae strains separated from...

Background: Listeria is a Gram-positive, non-spore forming, facultative anaerobic intracellular bacterium. The most important pathogens in mammals include Listeria monocytogenes and Listeria ivanovii. The former generally causes disease and death in both humans and animals while the latter performs sporadically and primarily causes illness in ruminant...

Background: The survival of pathogens in biofilms poses a threat to food safety. The aim of this study was to determine prevalence, antimicrobial resistance, and molecular characterization of Escherichia coli strains. Methods: Swab samples (n=144) were collected from biofilm formed on food contact surfaces in seafood pre-processing plant in India. E. coli was isolated and identified using uid ...

A polyphasic characterization of atypical isolates of Yersinia ruckeri (causative agent of enteric redmouth disease in trout) obtained from hatchery-reared brown trout Salmo trutta in South Carolina was performed. The Y. ruckeri isolates were biochemically and genetically distinct from reference cultures, including the type strain, but were unequivocally ascribed to the species Y. ruckeri, base...

Objectives: The purpose of this study was to investigate the phylogenetic groups, antibiotic resistance, resistance genes (ARGs), integrons, extraintestinal virulence and genetic diversity Escherichia coli isolates from human urinary tract infection. Methods: A total 100 E. were collected patients with infections in Kerala, South India. Antibiotic susceptibility testing all against different an...

Abstract There is a global concern and increasing reports regarding foodborne disease infections associated with consuming contaminated vegetables, seafood, meat, poultry products. Among bacterial pathogens globally, Salmonella , Escherichia coli Shigella were the most frequently implicated in causing food poisoning children adults. In Saudi Arabia, consumption rates of imported fresh fruits, m...

Acinetobacter sp isolates deserve special attention once they have emerged globally in healthcare institutions because they display numerous intrinsic and acquired drug-resistance mechanisms. This study assessed the antibiotic susceptibility profile, the presence of the genetic marker blaOXA-23, and the clonal relationship among 34 nosocomial isolates of Acinetobacter spp obtained at a hospital...

Toxic and fimbrial virulence factors as well as genetic diversity of 11 Escherichia coli O149:K91, F4 strains isolated from pigs with diarrhoea in Germany were examined. The ability of enterobacterial repetitive intergenic consensus – polymerase chain reaction (ERIC-PCR) to discriminate E. coli strains was evaluated. Two different virulence marker profiles: F4/EAST1/LTI/STII and F4/EAST1/LTI/ST...
