Inhibitory effects of alcoholic extracts of thyme on verotoxin pruduction of entro heorrhagic Escherichia coli o157:h7
Entrohemorrhagic Escherichia coli is a human pathogen that causes hemorrhagic colitis due to its verotoxin. It is an agent with food poisoning importance; a significant number of cases subsequntly develop hemolitic uremic syndrome (HUS) which is probably the most common cause of renal failure in childeren and occasionally resulting in death. Inhibition of bacterial growth in food is the most im...

متن کاملModified Vero cell induced by Bifidobacterium bifidum inhibits enterohemorrhagic Escherichia coli O157:H7 cytopathic effect
Enterohemorrhagic Escherichia coli (EHEC), such as E. coli O157:H7, are emerging food-borne pathogens worldwide. This micro-organism can damage the epithelial tissue of the large intestine. The cytotoxic effects can be neutralized by probiotics such as Bifidobacterium bifidum. Probiotics are viable cells that have beneficial effects on the health of the host. The preventing activity of B. bifid...
متن کاملFate of enterohemorrhagic Escherichia coli O157:H7 in bovine feces.
Dairy cattle have been identified as a principal reservoir of Escherichia coli O157:H7. The fate of this pathogen in bovine feces at 5, 22, and 37 degrees C was determined. Two levels of inocula (10(3) and 10(5) CFU/g) of a mixture of five nalidixic acid-resistant E. coli O157:H7 strains were used. E. coli O157:H7 survived at 37 degrees C for 42 and 49 days with low and high inocula, respective...
متن کاملEnterohemorrhagic Escherichia coli O157:H7 present in radish sprouts.
Using cultivation, immunofluorescence microscopy, and scanning electron microscopy, we demonstrated the presence of viable enterohemorrhagic Escherichia coli O157:H7 not only on the outer surfaces but also in the inner tissues and stomata of cotyledons of radish sprouts grown from seeds experimentally contaminated with the bacterium. HgCl2 treatment of the outer surface of the hypocotyl did not...
