Streptococcus suis strain LSS40

Streptococcus suis strain LSS40 is a Gram-positive cocci bacterium characterized by its presence in chains, pairs, and singles. This strain is a facultative anaerobe, indicating its ability to grow in both the presence and absence of oxygen, and it thrives optimally at a temperature of 37 degrees Celsius, fitting within the mesophilic temperature range. It possesses one membrane and one replicon, with no mobility due to the absence of flagella. S. suis LSS40 has a specialized habitat and exhibits a free-living biotic relationship. It is known to be pathogenic to a range of hosts, including Homo sapiens, Metazoa, Danio rerio, and Sus scrofa. The strain is associated with several serious health conditions in humans, including endocarditis, meningitis, septicaemia, and purulent meningitis, among others. These diseases highlight the strain's potential to cause severe infections, leading to systemic issues such as fever and cerebral ischemia. The presence of S. suis LSS40 in both animal and human hosts points to its ecological significance, suggesting a role in zoonotic transmission. This ability to infect multiple host species emphasizes the importance of understanding its pathogenic mechanisms and the need for vigilance in monitoring its presence in various environments. The strain's diverse health effects further underline its relevance in medical microbiology and public health.
