Distribution of Escherichia coli O157 in bovine fecal pats and its impact on estimates of the prevalence of fecal shedding

Article Abstract:

Studies done to investigate the distribution of Escherichia coli O157 in bovine feces are reported and its impact was assessed on the sensitivity of shedding survey results. Results of the study demonstrate that substantial improvement to the detection of E.coli O157 in bovine fecal pats can be achieved by increasing the number of samples tested per pat.

Analyses of the red-dry phenotype of an Escherichia coli O157:H7 strain and its role in biofilms formation and resistance to antibacterial agents

Article Abstract:

The rdar phenotype of strain 43895OR is similar to that described for certain strains of Salmonella and is important in multicellular behavior, bio-film production, and resistance to certain bacterial compounds. The studies of strain 43895OW attached to glass indicate that curli fibers could be expressed during attachment to glass.
