Genomic polymorphisms for Mycobacterium avium subsp. paratuberculosis diagnostics.

ABSTRACT: Mycobacterium avium subsp. paratuberculosis is an emerging pathogen of mammals and is being actively investigated as a possible zoonotic agent. The lack of reliable diagnostic assays has hampered rational assessment of the prevalence of this organism in humans and animals. We have used a comparative genomic approach to reveal genomic differences between M. avium subsp. paratuberculosis and its close relative M. avium subsp. avium, a highly prevalent environmental organism. From computational and DNA microarray-based study of two prototype strains, M. avium subsp. avium strain 104 and M. avium subsp. paratuberculosis strain K10, we have uncovered two types of large sequence polymorphisms (LSPs): those present in the former but missing in the latter (LSP(A)s) and those only present in the la
