Includes reference.

This study was carried out on 80 faecal samples collected from Friesian calves (one day to three months old) at Quena Governorate. Twenty calves were clinically healthy and 60 calves showed sever diarrhoea, with offensive odour and fever. Bacterological examinations revealed that 64 out of 80 faecal samples (80%) were positive to Enterobacteriaeceae. Bacterial isolates of the diseased calves were identified biochemically as; 37 (61.6%) strains of E. coli, 18 (30%) strains of Salmonella spp., 3(5%) strains of Pseudomonas spp., 2(3.3%) strains of Shigella spp.and from the clinically healthy calves 2 (10%), 1(5%), 1(5%),0% respectively.
