Verocytotoxic E. coli (VTEC) in Milk and Milk Products of Kanpur and Mathura, U.P., India
Page No. : 89-92
ABSTRACT
The aim of the present study was to know the occurrence of verocytotoxic E. coli (VTEC) by PCR in 87 milk samples (57 raw and 30 pasteurized) and 150 milk products (30 each of burfi, paneer, curd, rasugulla and milk powder) collected from Kanpur and Mathura, U.P. These isolates were further serotyped and then characterized for stx genes by PCR. Per cent positivity of VTEC in raw milk was found to be 7.01 (4/57). Pasteurized milk samples were free from VTEC strains. Milk products like peda and paneer showed per cent positivity of 6.66 (2/30) and 3.33 (1/30) for VTEC, respectively. Over all 2% (3/150) milk products were found positive for VTEC and the 7 isolates belonged to O60, O22, O55 and O102 serotypes and harboured stx2 gene.Keywords: Milk, milk products, serotype, stx, verocytotoxic E.coli
