Shigella dysenteriae strain 561031

Shigella dysenteriae strain 561031 is a Gram-negative, rod-shaped bacterium that typically exists in pairs or as singles. It is a facultative anaerobe, meaning it can survive in both oxygen-rich and oxygen-poor environments. This strain is classified as a chemoorganotroph, utilizing organic compounds as its energy source. The optimal growth temperature for S. dysenteriae strain 561031 is 37°C, within the mesophilic temperature range. This bacterium is characterized by the presence of flagella, although it is non-motile, which may suggest that its flagella do not contribute to movement in a conventional sense. S. dysenteriae strain 561031 possesses a single replicon and is surrounded by two membranes, consistent with the structure of Gram-negative bacteria. It has a free-living biotic relationship but primarily interacts with various hosts, including Homo sapiens, other Metazoa, and Primates. S. dysenteriae is well-known for its significant health impacts, causing diseases such as shigellosis, hemolytic uremic syndrome (HUS), and bacillary dysentery, which can lead to epidemics of Shigella dysentery. These pathogenic characteristics underscore the importance of understanding the ecological and biological dynamics of this strain, particularly its interactions with human hosts. The strain's adaptability to host-associated environments highlights the potential for transmission and outbreak, posing public health challenges that warrant ongoing research and surveillance.
