In: Assiut Veterinary Medical Journal 2003.v.49(97)Summary: Risk of acquiring verocytotoxin E. coli infections through ingestion of raw cow's milk continues to increase causing either sporadic cases or outbreaks. During June-September 2002, one hundred and ten samples were screened for the presence of verocytotoxin-producing E.coli (VTEC). Both milk samples (40) and fecal swabs (40) were collected from the same apparently healthy cows in dairy farms, moreover thirty samples of retail milk marketed in Assiut province were collected. Verocytoxin-producing E.coli was isolated from 14 (12.73%) of 110 samples after enrichment in mTSB (modified tryptic soya broth) supplemented with novobiocin, plating onto SMAC (sorbitol MacConkey agar) and then were identified using latex agglutination test.
