Streptococcus salivarius strain MIT 14-1770-C1

Streptococcus salivarius strain MIT 14-1770-C1 is a Gram-positive, cocci-shaped bacterium that typically forms chains or pairs. This strain is classified as a facultative anaerobe, allowing it to thrive in varying oxygen conditions. It is non-motile and lacks flagella, indicating that it does not have the means for active movement. The strain is mesophilic, thriving within a moderate temperature range optimal for growth. S. salivarius MIT 14-1770-C1 is host-associated, predominantly found in humans (Homo sapiens). Its biotic relationship is categorized as free-living, indicating that while it resides in a host, it can exist independently in certain environments. Importantly, this strain has been implicated in several health issues, including bacteremia, pneumonia, endocarditis, peritonitis, and meningitis. These associations highlight its potential pathogenicity in human health. The strain has a single replicon, which is characteristic of many bacteria, allowing for efficient replication and maintenance of genetic information. Notably, S. salivarius MIT 14-1770-C1 is nonsporulating, indicating that it does not form spores as a survival mechanism. The presence of S. salivarius in the human microbiome suggests its role in maintaining oral and systemic health, although its pathogenic potential underscores the importance of understanding its behavior in different environments and health contexts. This duality emphasizes the need for further research into its ecological interactions and potential therapeutic applications.
