Capnocytophaga canimorsus strain NCTC11921

Capnocytophaga canimorsus strain NCTC11921 is a Gram-negative, nonsporulating rod that exhibits a microaerophilic oxygen requirement and thrives optimally at 37.0°C. As a chemoheterotroph, this strain utilizes organic compounds as both its energy and carbon sources, reflecting its adaptation to diverse habitats. The rod-shaped morphology of C. canimorsus is characteristic of the genus, which is known for its unique metabolic capabilities and ecological versatility. The microaerophilic nature of this strain suggests that it may inhabit environments with limited oxygen availability, such as within the oral cavities of mammals, including dogs, and potentially in other niches where organic matter is present. Given its diverse habitat preferences and nutritional versatility, C. canimorsus strain NCTC11921 may play a significant role in the microbial communities of host organisms, contributing to the complex interactions within the microbiome. This trait highlights the potential for this bacterium to impact host health and the dynamics of microbial ecosystems, warranting further investigation into its ecological functions and contributions to its environments.
