Increased frequency of ColV plasmids and mannose-resistant hemagglutinating activity in an Escherichia coli K1 population.
The expression of traits linked to pathogenicity was studied in a population of Escherichia coli K1 strains. It was found that E. coli K1 strains isolated from extraintestinal infection harbor the ColV plasmid and express mannose-resistant hemagglutinating activity type VI with a high frequency. The presence of these properties may play a role in the ability of some E. coli K1 serogroups to invade.
