Streptococcus gordonii strain DD07

Streptococcus gordonii strain DD07 is a Gram-positive bacterium characterized by its cocci shape and arrangement in chains or pairs. This strain is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. It is non-motile and does not possess flagella, indicating that it does not move independently. The optimal growth temperature for S. gordonii strain DD07 is 37°C, which aligns with the average human body temperature, suggesting its adaptation to a host-associated habitat, specifically in humans (Homo sapiens). This mesophilic organism has a single replicon and a single membrane, features that are typical of many bacteria in its class. As a free-living organism, S. gordonii strain DD07 plays a role in the microbial community associated with human hosts. Its presence is significant in the oral cavity, where it contributes to the complex biofilm structure of dental plaque. Understanding the traits of S. gordonii strain DD07 enhances our knowledge of its ecological role in human health and disease, particularly in relation to oral microbiota and potential implications for dental health.
