Aggregatibacter actinomycetemcomitans str. 624

Aggregatibacter actinomycetemcomitans str. 624 is a Gram-negative, rod-shaped bacterium that exhibits facultative anaerobic growth, thriving optimally at 37.0°C. As a nonsporulating organism, it relies on a stable environment for survival and reproduction. This strain is classified as a chemoheterotroph, indicating that it derives its energy from organic compounds, which is consistent with its habitat within the host gut. The presence of A. actinomycetemcomitans in the gut suggests a potential role in the complex microbial communities that inhabit this environment. The bacterium’s ability to adapt to both aerobic and anaerobic conditions allows it to occupy diverse niches within the gut microbiome, where it may contribute to metabolic processes and nutrient cycling. While the specific ecological functions of this strain remain to be fully elucidated, its versatility in oxygen utilization and dependency on organic substrates underscore its potential importance in gut health and microbial interactions. Further research could illuminate its role in maintaining gut homeostasis or its interactions with other microbial species in the host.
