Identification and Characterization of Streptococcus pneumoniae. S. pneumoniae may occur intracellularly or extracellularly as gram-positive lanceolate diplococci, but can also occur as single cocci or in short chains of cocci. S. pneumoniae is a fastidious bacterium, growing best at 35-37°C with ~5% CO 2 (or in a candle-jar).

It is an important etiological agent of upper and lower respiratory tract infections (URTI and LRTI), bacteremia and septicemia. In addition to Optochin test, bile solubility test, and catalase test, Gram staining is one of the methods used to determine the presence of Streptococcus bacteria in a sample.
