Histophilus somni strain USDA-ARS-USMARC-63255

Histophilus somni strain USDA-ARS-USMARC-63255 is a Gram-negative, rod-shaped bacterium that exhibits both aerobic and facultative anaerobic metabolic capabilities. This strain thrives optimally at a temperature of 35.0°C, suggesting a preference for warm-blooded hosts within its ecological niche. As a host-associated microbe, H. somni is typically found in the respiratory and reproductive tracts of its hosts, indicating its possible role in the microbial communities associated with these environments. The dual oxygen requirement of this strain allows it to adapt to varying oxygen levels within its host, which may facilitate its persistence in diverse anatomical sites. The adaptation to host-associated habitats and the ability to function in both aerobic and anaerobic conditions may provide insights into its metabolic versatility and ecological interactions within the host environment. Understanding these traits is crucial for further investigations into the ecological roles and potential impacts of H. somni in its host's microbiome.
