Relationship between virulence gene profiles of atypical enteropathogenic Escherichia coli and Shiga toxin-producing E. coli isolates from cattle and sheep in New Zealand.
Virulence gene profiles of atypical enteropathogenic Escherichia coli (aEPEC) and Shiga toxin-producing E. coli (STEC) from cattle, sheep, and humans were examined to determine the relationship between pathotypes. Shared virulence factors (intimin, EHEC hemolysin, serine protease, and a type II secretion system) were identified, suggesting a dynamic evolutionary relationship between aEPEC and STEC.
