Streptococci. Streptococci are Gram-positive, non-motile, non-spore forming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes. The genus is classified on the basis of colony morphology, hemolysis, biochemical

Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. Streptococcus pneumoniae. This organism is a member of the normal human nasopharyngeal flora. There are more than 85 different antigenic types of S. pneumoniae, which are classified based on their capsule antigens. This organism is also the most common cause of sinusitis, acute bacterial otitis media, and conjunctivitis beyond early childhood. S. pneumoniae is also known to cause pneumonia, meningitis, and bacteremia.
