Capnocytophaga canimorsus strain H5594

Capnocytophaga canimorsus strain H5594 is a Gram-negative, microaerophilic, rod-shaped bacterium. It is classified as a chemoheterotroph, utilizing organic compounds for energy. This strain is non-motile and possesses flagella, although its primary habitat encompasses multiple environments. The optimal growth temperature for strain H5594 is 37°C, indicating its mesophilic nature. This bacterium has been identified in association with various hosts, including humans (Homo sapiens), domestic cats (Felis catus), and dogs (Canis lupus familiaris). Its free-living biotic relationship suggests that it can survive independently in diverse ecological niches. Notably, Capnocytophaga canimorsus strain H5594 is linked to several serious health effects, including bacteremia, endocarditis, meningitis, and various systemic infections like sepsis and septicemia. It is particularly concerning in cases of local wound infections and severe generalized infections, which may arise from interactions with its animal hosts. The presence of Capnocytophaga canimorsus in humans primarily occurs following close contact with pets, especially dogs and cats, highlighting the zoonotic potential of this organism. Understanding its pathogenic profile is crucial for managing infections and preventing severe health outcomes associated with this bacterium. The strain's non-sporulating nature further emphasizes the importance of direct contact in its transmission dynamics, offering insight into its ecological role and implications for public health.
