Description

Shigella flexneri K-227 is a Gram-negative, rod-shaped bacterium that exhibits a facultative anaerobic oxygen requirement, allowing it to thrive in various environments. It is classified as a chemoorganotroph, utilizing organic compounds as its energy source. The bacterium typically exists in pairs or singles and possesses flagella, which contribute to its mobility. The optimal growth temperature for S. flexneri K-227 is 37°C, aligning with the typical body temperature of its host organisms, indicating a strong adaptation to host-associated habitats. It is a mesophilic organism, thriving in moderate temperature ranges. Notably, S. flexneri K-227 contains a single replicon and is characterized by a double membrane structure, which is typical of Gram-negative bacteria. In terms of its biotic relationships, S. flexneri K-227 is free-living, though it is commonly associated with pathogenic roles in humans, particularly in causing shigellosis, an infectious disease marked by diarrhea. The absence of sporulation in this species suggests that it relies on other survival strategies in the presence of environmental stressors. Ecologically, the presence of S. flexneri K-227 in host-associated environments highlights its role in microbial dynamics within the gastrointestinal tract of humans. Its ability to move and adapt to varying conditions emphasizes its potential as a significant pathogen in clinical microbiology. Understanding its traits can aid in the development of strategies to manage infections and study its ecological impact in host environments. The accession number for reference is AFGY00000000.1.
