Pathogenic Escherichia coli strains cause a wide range of extra intestinal infections including urinary tract infection in humans and colibacillosis in poultry. They are classified into uropathogenic E. coli (UPEC) and avian pathogenic E. coli (APEC) with genetic similarities and variations. Their pathogenicity is related to the virulence-encoding genes like sfa</...

conclusions our findings show that lactobacillus strains with human origin had a mild inhibitory activity against the diarrheagenic e. coli, and these strains may be useful as probiotic candidates in prevention of intestinal infections caused by diarrheagenic e. coli. results a total of 20 lactobacillus isolates were identified from stool samples. lactobacillus fermentum was the most frequently...

Background. Persistent Escherichia coli asymptomatic bacteriuria (ASB) is common among persons with diabetes mellitus, but the duration of colonization and the rates of recolonization are unknown. We estimated the duration of colonization and the rate of recolonization among successively isolated E. coli from diabetic women with ASB and compared the virulence profiles with uropathogenic and com...

conclusions the rapid dissemination of non clonal multi-resistant ctx-m-1 producing e. coli isolates approved the need for further studies in our medical centers. results a total of 140(70%) non-duplicate esbl positive e. coli were determined. imipenem and amikacin were effective against 100% and 85% of all tested isolates respectively. co-resistance of esbl positive isolates to erythromycin, t...

objective: escherichia coli is the most prevalent etiologic agent of urinary tract infections which is the cause of about 80% of cases. enzymatic inactivation of aminoglycosides by aminoglycoside-modifying enzymes is the main mechanism of resistance to these antibiotics in escherichia coli. the aim of this study was the detection of aac(3)-iia gene among aminoglycoside resistant clinical isolat...

results we found a high number of pai markers such as pai icft073, pai iicft073, pai i536, pai iv536, pai ii j96 and pai ii536 significantly associated with upec. the pai iv536 was the most detected ones among fecal e. coli isolated from healthy people while pai i536, pai ii536 and pai ij96 were not seen. pcr phylogenetic groups typing revealed that uropathogenic strains were mainly found in b2...

Background: Foodborne infection caused by EnterotoxigenicEscherichia coli (ETEC) and Enteropathogenic Escherichia coli (EPEC) is one of the major health problems, particularly in the developing countries. Therefore, it is vital to identify the origin of food contamination to plan control strategies efficiently. Method: A tota...

in this study, 90 internal organ samples of poultry with symptoms of colibacillosis were obtained from maragheh poultry farms in east azerbaijan, iran. in total, 70 bacterial isolates were confirmed as escherichia coli (e. coli) strains using standard biochemical tests, and antibiotic sensitivity was determined by the disk diffusion method. antibiotics used in this study included ampicillin, pe...
