title: Understanding Mycobacterium avium subspecies hominissuis microaggregate mediated pathogenesis.
abstract: Mycobacterium avium subspecies hominissuis (MAH) is an opportunistic pathogen and causes nontuberculous infections in immune compromised individuals, an emerging problem that has been recognized worldwide. Understanding the pathogenesis of this organism is important as better treatment and prevention options are needed. Microaggregates form when two or more bacterial cells join at a surface. MAH forms micgroaggregates to promote its entry in to epithelial cells and cause infection. The mechanisms involved in the interaction between the microaggregate and the host are becoming clearer as the molecules involved in this process are being uncovered. Microaggregate Invasion Protein-1 (MIP-1) is now described as having a major role in the invasion of epithelial cells by MAH.
