Homologous Recombination in Mediates Diversification of Cell Surface Features and Transport Systems.

Illness caused by the pathogen is widespread and can range in severity from mild diarrhea to sepsis and death. Strains of isolated from human infections exhibit great genetic diversity, leading to the hypothesis that the genetic background of the infecting strain at least partially determines a patient's clinical course. However, although certain strains of have been suggested to be associated with increased severity, strain typing alone has proved insufficient to explain infection severity.
