Virulence patterns from septicemic Escherichia coli O78 strains.


Several septicemic Escherichia coli O78 strains, isolated from different sources, were characterized phenotypically and genotypically. Two avian isolates, one of which is known to carry the AC/I fimbriae, hybridized with the sfa determinant in colony dot-blot assay. Southern hybridizations with specific sfa probes, following pulsed-field gel electrophoresis… (More)
