Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Veterinary Medicine - Department of Internal Medicine and Infectious Diseases Summary: Neonatal calf diarrhea is one of the most important problems in young calves causing great economic losses., The objective of this study was to investigate serotypes, virulence genes, and antibiotic sensitivity testing of Escherichia coli isolated from buffalo and cattle calves at some places in Egypt. A total number of 160 fecal samples from diarrheic cattle and buffalo calves under one months old were examined bacteriologically for isolation of E. coli. All isolates were confirmed by PCR using 16SrRNA gene. Results showed that Overall 44 isolates typed as E. coli (27.5%); were belonged to serogroup O146 (50%), followed by O1 and O119 (13.5%) then O78(9.25%) and later O26 and O127 (6.8%). Epidemiological studies of E. coli were as the following: prevalence rate of enteric colibacillosis in the present study was (27.5 %). A higher prevalence rate was recorded in cattle calves (32.46 %) than buffalo calves (22.89%). The present study recorded a higher incidence in female calves (34.6%) than male calves (21.1%). Considering seasons; The results showed that the higher incidence was in summer (38.7%) followed by winter (31.5%) then spring (22.5%) then autumn (21.5%). Susceptibility was also evaluated for the incidence in calves of different ages; the results showed that the calves were more susceptible during the 1st then 2nd then 3rd then the 4th week post calving
