Shigella dysenteriae

Shigella dysenteriae is a Gram-negative, non-motile rod-shaped bacterium characterized by its facultative anaerobic metabolism and mesophilic growth preferences, with an optimal temperature of 37°C. This organism typically exists in pairs or as single cells and features two cellular membranes. It is a chemoorganotroph, deriving energy from organic compounds, and is primarily associated with host environments. S. dysenteriae is distinguished by its unique genomic structure, possessing three replicons. The genome is accessible through several accessions, including UAUQ00000000.1, UYIS00000000.1, and RTCP00000000.1. Its biotic relationship is defined as free-living, indicating its ability to thrive in association with hosts while possibly exhibiting some degree of independence from a specific host environment. This bacterium's ecological role is significant, as it is adapted to a host-associated habitat, suggesting that it may play a part in the microbial communities found within the gastrointestinal tracts of various hosts. The presence of flagella, despite its non-motility, underscores adaptation strategies that may facilitate its survival and interaction within the host environment.
