Capnocytophaga canimorsus strain NCTC11921

Capnocytophaga canimorsus strain NCTC11921 is a Gram-negative, microaerophilic rod-shaped bacterium that serves as a chemoheterotroph, deriving its energy from organic compounds. This strain is non-motile and has flagella, which may play a role in its environmental interactions. Optimal growth conditions for C. canimorsus occur at 37°C, categorizing it as mesophilic. This bacterium is free-living and has been identified in multiple habitats, indicating a versatile ecological presence. It has been associated with various hosts, including Homo sapiens, Metazoa, Canis lupus familiaris (domestic dog), and Felis catus (domestic cat), suggesting that it may inhabit environments shared with these species. C. canimorsus is clinically significant due to its association with a range of severe health effects in humans. These include bacteremia, endocarditis, meningitis, sepsis, cellulitis, and ocular infections, among others. The bacterium can lead to serious systemic infections and is particularly noted for causing infections following animal bites, particularly from dogs or cats. Understanding the pathogenic potential and ecological relationships of Capnocytophaga canimorsus strain NCTC11921 is essential for public health, especially in contexts involving pet ownership and animal interactions. The bacterium's capability to thrive in diverse environments and its association with various infections highlight its relevance in both clinical and ecological studies.
