Prevalence of Escherichia coli O157 in Saskatchewan cattle: Characterization of isolates by using random amplified polymorphic DNA PCR, antibiotic resistance profiles, and pathogenicity determinants
Article Abstract:
The prevalence of Escherichia coli O157 associated with feedlot cattle in Saskatchewan was determined in a 10-month long longitudinal study and a point prevalence study that varied from 2.5% to 45% in three different sites and 0% to a high of 57% in 20 different feedlots. Antimicrobial susceptibility testing of the E. coli O157 isolates revealed that 10 were multidrug resistant and that 73 and 5 were resistant to sulfisoxazole and tetracycline respectively.

Substratum topography influences susceptibility of Salmonella enteritidis biofilms to trisodium phosphate
Article Abstract:
Microbiological research indicates that the growth rate of microorganism Salmonella enteritidis on biofilms in glass flow cells is affected by trisodium phosphate solution at differing flow rates and substratum topography. High flow rates cause increased advective TSP flux activity. Artificial crevices of 0.5, 0.3 and 0.15 millimeter widths were applied to the biofilms. The microorganism grows far less well if no crevices are applied to the biofilm.

Treatment of Salmonella enterica serovar enteritidis with a sublethal concentration of trisodium phosphate or alkaline pH induces thermotolerance
Article Abstract:
The effect of pretreatment of Salmonella enterica serovar Enteritids with a sublethal concentration of trisodium phosphate (TSP) or alkaline pH on tolerance to lethal stresses, protein synthesis and membrane fatty acid composition are examined. The results suggest that the cytoplasmic membrane could play a significant role in the induction of thermotolerance and resistance to other stresses following TSP or alkaline pH treatment.
