Shigella sonnei strain FDAARGOS_776

Shigella sonnei strain FDAARGOS_776 is a Gram-negative bacterium characterized by its rod shape and a lack of mobility. This strain is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. It is a chemoorganotroph, deriving its energy from organic compounds. The optimal growth temperature for S. sonnei is 37°C, indicating its mesophilic nature, which aligns with typical human body temperatures, making it well-adapted to its hosts. S. sonnei primarily associates with Homo sapiens, as well as other metazoans, including Pteropodidae. This relationship underlines its role as a pathogen, as it is known to cause various health effects, particularly diarrheal diseases such as shigellosis, enterocolitis, and dysentery. The presence of two membranes indicates its classification as a Gram-negative bacterium, which is significant for its pathogenic mechanisms and resistance to certain antibiotics. The strain has a single replicon, which is typical for many bacteria, facilitating its replication and survival in host environments. S. sonnei is also free-living, suggesting it can exist independently in various habitats associated with its hosts. This adaptability may enhance its potential for transmission and survival outside of direct host interactions. In summary, the ecological and pathogenic traits of Shigella sonnei strain FDAARGOS_776 highlight its significant role in human health, particularly in causing gastrointestinal illnesses, while its habitat and nutritional adaptations underscore its evolutionary success in diverse environments.
