Rothia dentocariosa ATCC 17931

Rothia dentocariosa ATCC 17931 is a gram-positive, coccoid-shaped bacterium that thrives at mesophilic temperatures, demonstrating a preference for growth in moderate environments. This microbe is classified as a chemoheterotroph, utilizing organic compounds for both carbon and energy. Rothia dentocariosa is primarily found in the oral cavity, specifically in dental plaque, but it can also inhabit other body sites including the respiratory tract and, in some cases, it may be isolated from the gastrointestinal tract. As a gram-positive organism, Rothia dentocariosa exhibits a thick peptidoglycan layer, which contributes to its rigidity and staining characteristics during the Gram staining process. Its coccoid shape gives it a spherical appearance, which can often manifest in clusters or pairs. The mesophilic temperature preference suggests that this bacterium grows optimally at temperatures around 30-37°C, which is consistent with the human body temperature and indicates its adaptation to the human oral environment. Being a chemoheterotroph, Rothia dentocariosa relies on organic nutrients from its environment, primarily derived from dietary sources and metabolic products of other microorganisms in the mouth. This bacterium acts as a facultative anaerobe, allowing it to survive in both aerobic and anaerobic conditions, thereby thriving in the dynamic microbiome of the oral cavity. Rothia dentocariosa plays a significant role in oral health, as it can interact with other oral bacteria, influencing plaque formation and dental health. It is also of clinical interest because, under certain conditions, it has been associated with opportunistic infections, especially in immunocompromised individuals. Its ability to survive in various environments and its complex interactions with other oral microbes highlight its importance in both health and disease.
