Currently, it is known that evolution and spread of virulence factors, which are those that enable a bacterium to be harmful to the human body, are facilitated but the pathogenicity islands. These islands are one or more genes are related to virulence, and mobility genes, such as integrases or transposons.

PATHOGENICITY ISLANDS

Mobile genetic elements that contribute to spread and modify virulence, and they also mediate the movement of different genes that encode virulence factors.
