Shigella sonnei str. 75/02

Shigella sonnei str. 75/02 is a Gram-negative, rod-shaped bacterium that typically appears as single cells or in pairs. This strain optimally grows at a temperature of 37.0°C, which corresponds with the normal human body temperature, suggesting an adaptation to a host-associated habitat. As a chemoorganotroph, it derives energy from organic compounds, reflecting its reliance on a nutrient-rich environment often found within host organisms. Additionally, S. sonnei str. 75/02 is classified as a facultative anaerobe, indicating its capability to survive in both aerobic and anaerobic conditions, which may enhance its persistence in diverse microenvironments within the host. The ability of S. sonnei to thrive in the human gastrointestinal tract, coupled with its metabolic flexibility, positions it as a notable member of the enteric microbiota. Understanding these traits can provide insights into its survival strategies and potential interactions within the host, including its response to variations in oxygen availability and nutrient composition. This adaptability may contribute to its competitive edge in colonizing the gut, underscoring the importance of host-associated environments in shaping the physiological traits of pathogenic microbes like Shigella sonnei.
