Diarrheagenic Escherichia coli (DEC) are associated with frequent incidences of waterborne infections and pose health risk to individuals who contact water for domestic or recreational uses. Detection DEC pathotypes in drinking can be used as an indicator fecal contamination. This study aimed investigate the occurrence their capacity form biofilms samples collected from different sources. In th...

The present study aimed to evaluate the antibacterial effect and antioxidant potential of quercetin nanoparticles on drug-resistant E. coli O157 in New Zealand White Rabbits. Initial surveillance lasting two years (2018-2019) was performed isolate molecular detection some virulence genes drug-resistant E.coli strains circulating NZW rabbits Egypt.The selected E.coli O157 strain our experimental...

In the absence of pipe-borne water, many people in Africa, especially in rural communities, depend on alternative water sources such as wells, boreholes and rivers for household and personal hygiene. Poor maintenance and nearby pit latrines, however, lead to microbial pollution of these sources. We evaluated the abundance of Escherichia coli and the prevalence of pathogenic E. coli virulence ge...

In this study, we attempted to isolate Escherichia coli from healthy adults in Ho Chi Minh City, Vietnam, and characterized its antimicrobial resistance profile, extended-spectrum β-lactamase (ESBL) genotype, phylogenetic grouping and virulence gene profile. A total of 103 E. coli isolates were obtained, and most of them were antimicrobial resistant such to streptomycin (80.6%), tetracycline (6...

Enterohemorrhagic Escherichia coli (EHEC) of the O157:H7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human EHEC disease. The aim of the present study was to investigate the prevalence of E. coli O157: H7/NM in raw meat samples from two provinces of Iran. During a period from March 2010 to March 2011. Two hundred and ninety five raw meat samples were...

Microfluidic chip was successfully fabricated from polydimethylsiloxane (PDMS) and used for direct detection of E.coli O157:H7 in ground beef via anti-digoxigenin immuno-PCR. The PDMS channels were functionalized with 100 μg/ml streptavidin at room temperature for 6 min. A recovery of 60% ± 3.4 was obtained when bacterial cells were extracted from seeded ground beef using differential centrifug...

OBJECTIVE To develop a rapid and definite diagnostic test of bacterial enteritis caused by pathogenic enterobacteria, the most frequent etiologic agent of infectious enteritis in the world. METHODS A set of conventional PCR assays were applied to detect and identify salmonella, shigella, and E. coli O157:H7 directly from pure culture and fecal samples. The general primers of pathogenic entero...
