Aggregatibacter actinomycetemcomitans HK1651

Aggregatibacter actinomycetemcomitans HK1651 is a Gram-negative, non-motile rod-shaped bacterium that inhabits the host gut. As a chemoheterotroph, it derives its energy from organic compounds, which is consistent with its ecological niche in the gut environment where it likely interacts with various substrates from the host's diet. This species is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic conditions, which is advantageous in the fluctuating oxygen levels characteristic of the gut microbiome. The optimal growth temperature for A. actinomycetemcomitans HK1651 is 37°C, placing it within the mesophilic temperature range, conducive to its survival in warm-blooded hosts. A. actinomycetemcomitans HK1651 is nonsporulating and possesses a single replicon, indicating a streamlined genetic organization. The presence of flagella may suggest adaptations for potential motility, although the bacterium is noted to be non-motile. Understanding the traits of A. actinomycetemcomitans HK1651 emphasizes its role within the gut microbiota, where it may contribute to the complex interactions among microbial communities. Its ability to thrive in varying oxygen levels and temperature helps maintain its presence in the dynamic gut environment, potentially influencing host health and disease states. The accession number NZ_CP007502.1 provides a reference for further genetic and functional studies on this bacterium.
