Shigella flexneri 4c str. 1205

Shigella flexneri 4c str. 1205 is a Gram-negative rod-shaped bacterium that is classified as a chemoorganotroph, utilizing organic compounds for energy. This organism is facultative, meaning it can thrive in both aerobic and anaerobic environments. It typically inhabits host-associated environments, indicating a strong association with living hosts. In terms of cellular arrangement, S. flexneri 4c str. 1205 is observed in pairs or singles, which is characteristic of its growth pattern. The bacterium is motile, possessing flagella that facilitate its movement. It thrives optimally at a temperature of 37°C, which is within the mesophilic range, allowing it to grow well in the human body, where it often causes infections. The genetic makeup of S. flexneri 4c str. 1205 is characterized by four replicons, suggesting a complex genomic structure. The bacterium has a double membrane system, which is typical for Gram-negative bacteria, providing structural integrity and protection against environmental stresses. Importantly, S. flexneri 4c str. 1205 does not undergo sporulation, a trait that indicates its reliance on its host environment for survival and reproduction. From an ecological perspective, the free-living nature of this bacterium, combined with its pathogenic potential, highlights its role in the microbiome of humans and its significance in public health. The ability to exist in host-associated environments while being motile and adaptable to varying oxygen conditions allows S. flexneri 4c str. 1205 to effectively colonize and persist in human hosts, contributing to the transmission of shigellosis.
