Aggregatibacter actinomycetemcomitans RhAA1

Aggregatibacter actinomycetemcomitans RhAA1 is a Gram-negative, rod-shaped bacterium classified as a nonsporulating, facultative anaerobe. This microbe thrives optimally at 37.0°C, which corresponds to the average human body temperature, suggesting a possible adaptation to a host-associated lifestyle. As a chemoheterotroph, Aggregatibacter actinomycetemcomitans RhAA1 derives its energy from organic compounds, which aligns with its habitat within the host gut. The presence of this bacterium in the gut environment may indicate its role in the complex microbial community that contributes to the host's digestion and metabolism. Its facultative anaerobic nature allows it to survive in both oxygen-rich and oxygen-poor conditions, further enhancing its adaptability within the diverse gut ecosystem. These traits suggest that Aggregatibacter actinomycetemcomitans RhAA1 may play a role in metabolic processes that are essential for the host's health, potentially influencing nutrient absorption and immunity. Understanding the specific interactions of this bacterium within the gut microbiome could provide insights into its contributions to host physiology and overall gut health.
