Mycobacterium avium subsp. hominissuis TH135

Mycobacterium avium subsp. hominissuis TH135 is a Gram-positive, rod-shaped bacterium that typically exists in a single-cell arrangement. This subspecies is classified as a chemoorganotroph, indicating that it derives energy from organic compounds, which is particularly relevant to its habitat that is host-associated. M. avium subsp. hominissuis TH135 thrives optimally at a temperature of 37.0°C, suggesting an adaptation to the warm environments found within a host organism. As a microaerophile, this bacterium requires a reduced level of oxygen for its metabolic processes, which may reflect its ecological niche within host tissues where oxygen concentrations can be lower than atmospheric levels. The specific interactions of M. avium subsp. hominissuis TH135 with its host environment remain to be fully explored, but its traits suggest a potential role in the complex microbiota associated with various host species. Given its chemoorganotrophic lifestyle and microaerophilic requirements, M. avium subsp. hominissuis TH135 may contribute to the nutrient cycling within the host's microbiome, highlighting the intricate relationships between microbial inhabitants and their hosts.
