Aggregatibacter actinomycetemcomitans serotype b str. SCC1398

Aggregatibacter actinomycetemcomitans serotype b str. SCC1398 is a Gram-negative, rod-shaped bacterium classified as a chemoheterotroph, indicating that it derives energy from organic compounds. This organism is a facultative anaerobe, meaning it can survive in both oxygen-rich and oxygen-poor environments. It is non-motile, despite having flagella, which suggests that its movement is not a primary characteristic of its life cycle. SCC1398 is typically found in the host gut, highlighting its role in the microbiome of the digestive system. Its optimal growth temperature is around 37°C, making it mesophilic, as it thrives within a temperature range that is conducive to human body temperature. The bacterium possesses a single replicon and does not undergo sporulation, which suggests a stable replication process under suitable environmental conditions. The presence of Aggregatibacter actinomycetemcomitans in the gut may influence the overall microbial community structure and function. As part of the gut microbiome, it could play a role in digestion or in maintaining the balance of microbial populations, which is essential for host health and disease prevention. Understanding its characteristics can provide insights into its ecological role and potential implications for human health, particularly in the context of oral and systemic diseases where this bacterium is often implicated.
