Ontology: Streptococcus (C0038402)

Definition (NCI) A genus of Gram-positive bacteria in the phylum Firmicutes and the lactic acid bacteria group.
Definition (NCI) Any bacteria that is not assigned to the species level but can be assigned to the Streptococcus genus level.
Definition (MSH) A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.
