Streptococcus suis strain ISU2812 Ssuis28-12_c436

Streptococcus suis strain ISU2812, designated as Ssuis28-12_c436, is a Gram-positive bacterium characterized by its cocci shape and arrangement in chains, pairs, and singles. This strain is a facultative anaerobe, thriving optimally at a temperature of 37°C, and is categorized as mesophilic. It possesses a single membrane and is non-motile, lacking flagella despite their presence in the general classification of Streptococcus. The habitat of Ssuis28-12 is specialized, indicating a specific ecological niche it occupies. This strain has a notable biotic relationship, being free-living and capable of infecting various hosts, including Homo sapiens, Metazoa, Danio rerio, and Sus scrofa. It is associated with a range of health effects, particularly severe conditions such as endocarditis, meningitis, septicemia, and other streptococcal diseases, which can lead to symptoms including fever and systemic infections. The ability of S. suis to cause significant health issues in multiple hosts highlights its ecological versatility and potential as a zoonotic agent. Understanding its biological traits and pathogenic mechanisms is crucial for managing infections it causes in both humans and animals, emphasizing the importance of monitoring and researching this strain in clinical and veterinary microbiology.
