Citrobacter freundii strain R47

Citrobacter freundii strain R47 is a Gram-negative, rod-shaped bacterium characterized by its facultative anaerobic metabolism and the presence of flagella, which aids in motility. This strain has been identified in various habitats, including hospital sewage, the intestinal tract of different hosts, sewage, soil, and surface waters. C. freundii strain R47 is known for its role as an opportunistic pathogen, causing infections in humans and a diverse range of animal hosts. In humans, it has been associated with urinary and respiratory tract infections, as well as wound infections. The strain also poses health risks to various animals, including horses, dogs, cats, and aquatic species, leading to similar respiratory and urinary tract infections. Notably, it has been documented in a wide array of hosts, which includes Homo sapiens, domestic animals like Canis lupus familiaris and Felis catus, and various aquatic species such as Tilapia and Cyprinus carpio. Genetically, C. freundii strain R47 possesses two replicons, indicating a complex genetic structure that may contribute to its adaptability in diverse environments. The strain is nonsporulating, which may reflect its ecological strategies for survival and proliferation in nutrient-rich habitats like sewage and the intestinal tracts of its hosts. The ecological versatility of C. freundii strain R47 underscores its potential impact on both human health and animal welfare, particularly in environments where these organisms cohabit, demonstrating the interconnectedness of microbial life and the significance of monitoring opportunistic pathogens in clinical and environmental settings.
