Fig. 5From: Antimicrobial growth promoters approved in food-producing animals in South Africa induce shiga toxin-converting bacteriophages from Escherichia coli O157:H7.Electrophoresis in a 0.8% agarose gel digestion by NdeI restriction enzyme of Stx bacteriophage DNA induced by flavophospholipol and isolated from cattle O157:H7 strains. M - molecular size markers. The right side of the figure shows marker band sizes. Bacteriophages 75 and 79 showed very faint bandsBack to article page
