Extractable organic components and nutrients in wastewater from dairy lagoons influence the growth and survival of Escherichia coli O157:H7

Article Abstract:

The influence of wastewater components from dairy lagoons on the survival and growth of pathogenic strains of Escherichia coli O157:H7 is examined. The results have shown that the chemical components, protozoa and coliphages in wastewater have inhibited the growth of freshly introduced pathogens from manure, although the wastewater has provided sufficient nutrients to naturally occurring human pathogens.

Influence of apple cultivars on inactivation of different strains of Escherichia coli O157:H7 in apple cider by UV irradiation

Article Abstract:

The effect of different apple cultivars upon the UV inactivation of Escherichia coli O157:H7 strains within unfiltered apple cider was studied and presented. Findings of the study reveal that regardless of the apple cultivar used, processed by 14mJ of UV irradiation, a minimum 5-log reduction is achieved for all of the strains of E.coli O157:H7 tested.

Shiga toxin and Shiga toxin-encoding phage do not facilitate Escherichia coli O157:H7 colonization in sheep

Article Abstract:

The Shiga toxin producing strains of Escherichia coli (STEC) are dependent on globotriaosylceramide (Gb3) present in the vascular endothelium of the gastrointestinal tracts of the ruminant animals. The wild type Escherichia coli o157:H7 was found to be similar to the isogenic mutant stx2 in terms of durations of colonization.
