Introduction

The anaerobic Gram-positive cocci (also known as peptococci and peptostreptococci) discussed in this chapter are limited to firmicutes with low mol% G+C. They are Peptococcus, Peptostreptococcus, Anaerococcus, Peptoniphilus, Gallicola, Finegoldia, Micromonas, Ruminococcus, Coprococcus and Sarcina. All except Anaerococcus, Peptoniphilus, Gallicola, Finegoldia and Micromonas belong to the classical family Peptococaceae (Rogosa, 1974). During the last 10 years, many members of the old genus Peptostreptococcus were transferred to many other genera. Most anaerobic Gram-positive cocci belong to the normal flora of the human gastrointestinal tract, vagina and oral cavity and often are found in human clinical specimens (Brook and Frazier, 1990; Ezaki et al., 1992). (Most human clinical isolates were identified as peptostreptococci.) Phylogenetically, anaerobic Gram-positive cocci belong to the phylum Clostridium. Indeed, based on 16S rRNA sequences, all species of the genus...
