Abstract EN
Calf diarrhea is one of the major health challenges in cattle herds.
The bacteriological examination of fecal samples collected from apparently healthy and diarrheic calves’ revealed isolation of 26 E.
coli isolates out of 56 calves with an incidence of 46.4%.
Serogroups O1, O26, O44, O55, O115, O119, O125, O146, and O151 were identified from the collected fecal samples.
Using PCR all isolates was positive for ompA gene species specific for E.
coli.
While stx1 and eaeA genes detected with incidence of 3.8 and 19.2% respectively from the isolates.
The presence of stx2 gene was negative in the fecal isolates.
Among colostrum samples 4 E.
coli isolates were detected and serogrouped to O26, O55 and O119.
They were negative for eaeA, stx1 and stx2 except strain number 4 (O55) was positive for stx1.
E.
coli strains were sensitive to norfloxacin (80.7%) and resistant to ampicillin and cefotaxime (100% each).
Based on our findings, there was no association between occurrence of E.
coli and age of calf (2–14 days), while bottle feeding calf colostrum may be a source of E.
coli contamination.
