Streptococcus suis strain SS997

Streptococcus suis strain SS997 is a Gram-positive cocci bacterium that typically arranges itself in chains, pairs, or as singles. It is a facultative anaerobe, displaying adaptability to both aerobic and anaerobic environments. This strain is classified as mesophilic, with an optimal growth temperature of 37°C, indicating its preference for moderate temperature conditions. S. suis strain SS997 is non-motile and does not possess flagella, which is consistent with its free-living biotic relationship. This bacterium has a singular replicon and a single membrane structure. It is found in specialized habitats and exhibits a variety of host interactions, including associations with Homo sapiens (humans), Metazoa, Danio rerio (zebrafish), and Sus scrofa (domestic pigs). The health implications of S. suis strain SS997 are significant, as it is associated with a range of severe diseases in humans. These include endocarditis, meningitis, septicemia, endophthalmitis, sepsis, arthritis, and purulent meningitis, among others. The strain has also been linked to cerebral ischemia, systematic infections, fever, endometritis, and spinal canal infection. The diversity of health effects associated with S. suis strain SS997 highlights its potential pathogenicity and the importance of understanding its ecological role in various hosts. As a free-living organism, it may play a role in the microbial dynamics within its specialized habitats, potentially influencing the health of both animal and human populations.
