Shigella flexneri K-227

Shigella flexneri K-227 is a nonsporulating, rod-shaped bacterium that exhibits a Gram-negative cell wall structure and typically arranges itself in pairs or singles. This strain thrives optimally at a temperature of 37.0°C, which aligns with the physiological temperatures of many mammalian hosts, reflecting its adaptation to a host-associated habitat. As a chemoorganotroph, Shigella flexneri K-227 derives its energy from organic compounds, which is consistent with its role in a host environment where it exploits available nutrients. The facultative anaerobic nature of this microbe allows it to adapt to varying oxygen levels, making it versatile in its metabolic processes. Such adaptability may contribute to its survival and persistence in diverse host conditions. The association of Shigella flexneri with host organisms highlights its potential interactions within the microbiome, where it may compete with other microbial species for resources or engage in host-microbe dynamics. Understanding the traits of Shigella flexneri K-227 not only provides insight into its biological and ecological roles but also underscores the importance of studying host-associated microbes in the context of health and disease. This strain exemplifies the complex interplay between microbial life and host environments, which can influence both microbial behavior and host responses.
