Structure, Classification and Antigenic Types
The anaerobic cocci are a physiologically diverse group that has recently undergone significant taxonomic changes. Anaerobic gram-positive cocci of clinical significance are found in three gram-positive genera (Peptostreptococcus, Gemella, and Streptococcus) and one gram-negative genus (Veillonella). There are other genera of anaerobic cocci, but they are rarely isolated from clinical specimens. Not all anaerobic cocci require stringent anaerobic conditions; for example, strains of Streptococcus intermedius are quite aerotolerant and may grow under reduced oxygen tension. Anaerobic cocci may be proteolytic or saccharolytic or both. They produce a variety of short-chain volatile fatty acids (i.e., acetic, propionic, butyric, caproic, and lactic acids) from the fermentation of simple sugars and amino acids. Both P magnus and P anaerobius possess species-specific cell wall antigens; in other anaerobic cocci, species-specific antigens have not yet been identified. Peptostreptococcus and Streptococcus are the most clinically important genera, with P magnus as the most frequent clinical isolate.
