Streptococcus Identification and Work Up

Streptococcus is a genus of coccus gram positive bacteria. They typically grow in chains of pairs as cell division occurs along a single axis in this family of bacteria. Most species in the streptococcus genus are oxidase negative, catalase negative, and most are facultative anaerobes. Many streptococcal species are not intact pathogenic and are part … Continue reading Streptococcus Identification and Work Up
