Prevalence and Comparative Studies of Some Major Serotype of E.Coli from Cattle and Buffalo Calf Scour

A study was carried out to find the different serotype of E.coli isolates from the young cattle and buffalo calves affected with calf scours. Different strains of E. coli were isolated from 30 cases of calf scour from both cattle and buffalo calves each. All the isolates of E. coli were typed for ʹOʹ antigen. The relationship of serotypes of E. coli to each case showed that two of the twenty six serotypes were common and appeared most virulent in both the species
