A total of 179 urine samples were collected from patients suffering urinary tract infections admitted and visit Al-Hilla General Teaching Hospital in City, during a period April 2021 to December 2021, both sex (male female). Out 179,123 (68.7%) positive culture, whereas 56 (31.3%) showed no bacterial growth, To confirm the identification E. coli by use selective media (EMB agar medium, biochemi...

Hybrid strains Escherichia coli acquires genetic characteristics from multiple pathotypes and is speculated to be more virulent; however, understanding their pathogenicity elusive. Here, we performed genome-based characterization of the hybrid enteropathogenic (EPEC) enterotoxigenic E. (ETEC), that cause diarrhea mortality in children. The virulence genes isolated different sources South Korea ...

Listeriolysin is a virulence factor that appears to be necessary for the intracellular survival of Listeria monocytogenes. As shown in this investigation, listeriolysin is produced in only small amounts by clinical isolates of L. monocytogenes belonging to the serogroup 1/2a, but its synthesis can be induced by heat shock and to a lesser extent by oxidative stress. In addition to about 15 heat ...

The gram-positive bacterium Listeria monocytogenes is a facultative intracellular pathogen. The only known property of L. monocytogenes which has been shown to be involved in virulence is a hemolysin, listeriolysin (J. L. Gaillard, P. Berche, and P. Sansonetti, Infect. Immun. 52:50-55, 1986; S. Kathariou, P. Metz, H. Hof, and W. Goebel, J. Bacteriol. 169:1291-1297, 1987). Using our previously o...

In this study, virulence factors such as serum resistance, aerobactin iron uptake systems, adhesins (type 1 fimbria, P S afimbrial adhesins), haemolysine, uropathogenic spesific protein and cytotoxic necrotizing factor in 45 Escherichia coli isolates from dogs cats with urinary tract genital system infections, were investigated by both phenotypic methods molecular methods. PCR examinations of E...
