Streptococcus suis strain WUSS351

Streptococcus suis strain WUSS351 is a Gram-positive, cocci-shaped bacterium that typically forms chains, pairs, or singles. This strain is classified as a facultative anaerobe and thrives optimally at a temperature of 37°C, indicating its mesophilic nature. Notably, it possesses a single membrane and one replicon, emphasizing its simplicity in cellular structure. S. suis WUSS351 is non-motile, lacking flagella, which suggests a reliance on other means for movement and colonization in its specialized habitat. This bacterium is free-living and has been identified as a pathogen with a broad host range, affecting Homo sapiens, various Metazoa, Danio rerio (zebrafish), and Sus scrofa (pigs). It is associated with several serious health conditions, including endocarditis, meningitis, septicaemia, endophthalmitis, arthritis, and sepsis. The strain has been implicated in systemic infections and other streptococcal diseases, leading to symptoms such as fever, endometritis, and spinal canal infections. The ecological implications of S. suis WUSS351 are significant, particularly in its interactions with both animal and human hosts. Given its ability to cause severe infections, understanding its biological traits and pathogenic mechanisms is crucial for developing strategies to manage and prevent diseases associated with this strain. The existence of this strain in diverse hosts highlights the potential for zoonotic transmission and the need for vigilance in both veterinary and human health contexts.
