Streptococcus suis strain WUSS327

Streptococcus suis strain WUSS327 is a Gram-positive, cocci-shaped bacterium that exhibits a characteristic arrangement in chains, pairs, and singles. This strain is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments. Its optimal growth temperature is 37°C, situating it within the mesophilic temperature range. Notably, S. suis WUSS327 does not exhibit mobility, as it lacks flagella. It possesses a single replicon and a single membrane structure, indicating a simple cellular organization. This bacterium is free-living and can be found in specialized habitats. S. suis is known to have a diverse range of hosts, including Homo sapiens (humans), various Metazoa (multicellular animals), Danio rerio (zebrafish), and Sus scrofa (domestic pigs). This host versatility is critical as it allows the bacterium to adapt and thrive in different biological contexts. The strain has significant health implications, being associated with various severe conditions such as endocarditis, meningitis, septicemia, and purulent meningitis, among others. These health effects highlight its potential pathogenicity in humans and other species. The ecological role of S. suis strain WUSS327 underscores its importance in both human health and veterinary contexts, particularly due to its ability to infect multiple hosts and cause serious diseases. This adaptability may facilitate its transmission and persistence in the environment, making it a noteworthy subject for further microbiological study.
