Pathogenicity islands are _______.

Question

Quizplus · Accepted Answer

Pathogenicity islands are distinct gene clusters within the genome of a bacterium that are acquired through horizontal gene transfer. These clusters contain genes that can confer pathogenic traits to the bacterium, such as toxin production, adhesion to host cells, or evasion of the host immune system. They are not enzymes, groups of organisms, or tissues, but rather segments of DNA that can make a non-pathogenic organism capable of causing disease.
