Comparative genomics between human and animal associated subspecies of the Mycobacterium avium complex: a basis for pathogenicity.

ABSTRACT:

Background

A human isolate of Mycobacterium avium subsp. paratuberculosis (M. paratuberculosis 43525) was sequenced and compared genomically to other mycobacterial pathogens. M. paratuberculosis 43525 was recently isolated from a patient with ulcerative colitis and belongs to the M. avium complex, a group known to infect both humans and animals. While M. paratuberculosis is a known pathogen of livestock, there are only 20 human isolates from the last 20 years, therefore we took the opportunity to perform a whole genome comparison between human and animal mycobacterial pathogens. We also compared virulence determinants such as the mycobactin cluster, PE/PPE genes and mammalian cell entry (mce) operons between MAC subspecies that infect animals and those that infect humans.
