A study on association of virulence determinants of verotoxic Escherichia coli isolated from cattle calves.

Aim: The present study was conducted to find the association among virulence determinants of verotoxic Escherichia coli (VTEC) isolated from cattle calf feces.

Materials And Methods: A total of 216 cattle calf fecal samples were collected aseptically and processed under required conditions for the isolation of E. coli.

Prevalence of vero toxic Escherichia coli in fecal samples of domestic as well as wild ruminants in Mathura districts and Kanpur zoo.

Aim: The present study was planned to reveal the prevalence of verocytotoxigenic Escherichia coli (VTEC) in fecal samples of domestic and wild ruminants in Mathura district and Kanpur zoo.

Materials And Methods: A total of 240 fecal samples comprising 60 each of cattle, buffalo, sheep and deer from Mathura districts and Kanpur zoo were screened for the presence of E. coli and VTEC genes positive by polymerase chain reaction (PCR).
