Description
Summary:Pathogenicity island are inserted DNA fragments in the bacterial chromosome that confer a variety of virulence traits tothe microorganisms. Among this variety of virulence properties we can SEE/: the ability of adhering and invading the host cells, toxinsproduction, iron uptake and the synthesis of Type Three Secretion System, a molecular device that allows the effectors molecules translocationinside the host cells. The feature of acquiring virulence traits in one genetic event allows the formation of new pathogens, aswell the pathogenic microorganism’s evolution.
