Streptococcus suis strain LSS96

Streptococcus suis strain LSS96 is a Gram-positive bacterium characterized by its cocci shape, which typically arranges in chains, pairs, or singles. This strain is a facultative anaerobe, thriving in environments with or without oxygen, and it is mesophilic, with an optimal growth temperature of 37°C. Notably, LSS96 has a single membrane and one replicon, which is relevant for its genetic stability and replication. This strain is non-motile, indicating it does not possess flagella, and it is classified as free-living, suggesting it does not rely on a host for survival under certain conditions. S. suis has a broad host range, affecting Homo sapiens (humans), various Metazoa, Danio rerio (zebrafish), and Sus scrofa (pigs). Clinically significant, S. suis strain LSS96 is associated with a variety of health issues in humans, including endocarditis, meningitis, septicaemia, endophthalmitis, and arthritis, among others. These conditions highlight its potential to cause serious systemic infections, such as septicemia and purulent meningitis, which can lead to severe health consequences. Understanding the biological and ecological characteristics of S. suis strain LSS96 is crucial, particularly in the context of zoonotic transmission, given its presence in both animal and human hosts. Its capacity to thrive in specialized habitats and its diverse pathogenic potential underscore the need for ongoing surveillance and research to mitigate its impact on public health.
