Citrobacter freundii strain MGH152

Citrobacter freundii strain MGH152 is a Gram-negative, rod-shaped bacterium identified as a facultative anaerobe. This strain is characterized by its presence of flagella, which aids in motility. It is known to inhabit diverse environments, including hospital sewage, intestinal tracts, sewage systems, soil, and surface waters. The strain has been associated with a variety of hosts, including Homo sapiens (humans), domestic animals such as dogs (Canis lupus familiaris), cats (Felis catus), and rabbits (Oryctolagus cuniculus), as well as various aquatic species like tilapia, carp (Cyprinus carpio), and even larger marine animals like Mola mola. This broad host range indicates its adaptability and potential for opportunistic infections across different species. C. freundii strain MGH152 is notable for its role in causing opportunistic infections. In humans, it is linked to urinary and respiratory tract infections. In veterinary contexts, it can lead to respiratory tract infections in dogs and horses, pleuritis and urinary tract infections in cats, among other bacterial infections in various animals. The strain does not undergo sporulation and has a single replicon. Its presence in both hospital settings and natural environments suggests a significant ecological role, particularly in the context of microbial communities in sewage and intestinal microbiomes. This adaptability underlines the importance of monitoring C. freundii in both clinical and environmental microbiology due to its potential impact on health across multiple species.
