Virulence Factors And Antibiotic Resistance Of Escherichia Coli O157:H7 Isolated From Ogun River, Abeokuta Metropolis, Nigeria, Lateefat M. Ewuoso, Saka A. Balogun, Sarafadeen O. Kareem, Temilade F. Akinhanmi

Applied Environmental Research

Although Escherichia coli (E. coli)is a harmless gut microbe in man, some strains of this bacterium are pathogenic due to the acquisition of virulence factors. The aim of this study isto investigate E. coli O157:H7 strains isolated from Ogun River, Abeokuta metropolis, for virulence factors and antibiotic resistance. Water samples were collected bimonthly from six different locations over a period of six months. The samples were cultured on Sorbitol MacConkey Agar and E. coli O157:H7 isolates were confirmed through serological characterization using the latex agglutination test. The presence of virulence genes (stx1, stx2, eae, and hylA) in the isolates was …
