Article Abstract:
Composite wild bird feces collected at regular intervals from a garden feeding station in southwest Scotland over a 3-year period were examined for verocytotoxin-producing Escherichia coli O157 causing infections in humans. The findings indicate that VTEC O157 appears and disappears from cattle herds over time, and it might be that local bird populations play a role in the spread of the organism between farms and possibly over larger distances due to migratory habits.

Article Abstract:
A study was conducted by characterizing different bovine Escherichia coli (EHEC) O165:H25 isolates to assess their potential to cause EHEC disease in humans. It showed that bovine O165:H25 isolates could carry virulence factors of EHEC that are associated with EHEC-related disease in humans, particularly hemorrhagic colitis and hemolytic-uremic syndrome, which might represent a considerable risk for human infection.

Article Abstract:
Shiga toxin-producing Escherichia coli isolates from two 2006 outbreaks are compared to other O157:H7 isolates for their virulence genotype, biofilm formation and stress responses. The studies have also demonstrated a cooperative biofilm formation involving an Escherichia coli O157:H7 strain and a non-O157:H7 strain.
