The strains formerly classified as Streptococcus anginosus or "Streptococcus milleri" have now been recognized as three distinct species, Streptococcus anginosus, Streptococcus constellatus, and Streptococcus intermedius. Streptococcus morbillorum has been transferred into the genus Gemella. Four new species within the genus Peptostreptococcus were recently named. A recent addition to the genus Clostridium is Clostridium argentinense, which includes Clostridium botulinum type G. Two new species of Actinomyces have been introduced: Actinomyces georgiae and Actinomyces gerencseriae. Arachnia propionica was shown to be related to propionibacteria and has been renamed Propionibacterium propionicum. Eubacterium yurii was named to contain "test-tube brush" bacteria found in subgingival plaque. Lactobacillus uli and Lactobacillus rimae are obligately anaerobic lactobacilli found in periodontal pockets. Bilophila is a new genus of gram-negative bacilli. Wolinella recta and Wolinella curva are now included in the genus Campylobacter. The taxonomic position of Mobiluncus, currently assigned to the family Bacteroidaceae, remains uncertain.

D002167 Campylobacter A genus of bacteria found in the reproductive organs, intestinal tract, and oral cavity of animals and man. Some species are pathogenic.
D003013 Clostridium A genus of motile or nonmotile gram-positive bacteria of the family Clostridiaceae. Many species have been identified with some being pathogenic. They occur in water, soil, and in the intestinal tract of humans and lower animals.
D005260 Female Females
D006089 Gram-Negative Anaerobic Bacteria A large group of anaerobic bacteria which show up as pink (negative) when treated by the Gram-staining method. Gram Negative Anaerobic Bacteria
D006094 Gram-Positive Bacteria Bacteria which retain the crystal violet stain when treated by Gram's method. Gram Positive Bacteria
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001439 Bacteroides A genus of gram-negative, anaerobic, rod-shaped bacteria. Its organisms are normal inhabitants of the oral, respiratory, intestinal, and urogenital cavities of humans, animals, and insects. Some species may be pathogenic.
D013291 Streptococcus A genus of gram-positive, coccoid bacteria whose organisms occur in pairs or chains. No endospores are produced. Many species exist as commensals or parasites on man or animals with some being highly pathogenic. A few species are saprophytes and occur in the natural environment.
