It is usually cultured in media that contain blood. They are usually found in pairs (diplococci ) and do not form spores and are nonmotile. On blood agar, colonies characteristically produce a zone of alpha (green) hemolysis, which differentiates S. pneumoniae from the group A (beta hemolytic) streptococcus, but not from commensal alpha hemolytic (viridans) streptococci which are co-inhabitants of the upper respiratory tract. Microbiology of Streptococcus pneumoniae Chronic bronchitis Hospital and community acquired pneumonia.
