Hallella is a Gram-negative, non-spore-forming, anaerobic and non-motile genus of bacteria from the family of Prevotellaceae with on known species ( Hallella seregens ). [2] [1] [3] [4] [5] Hallella is named after the American microbiologist Ivan C. Hall. [2] Hallella seregens has been isolated from a gingival crevice of a patient. [6] [7]
Prevotella melaninogenica is a species of bacterium in the normal microbiota of the upper respiratory tract. It is an important human pathogen in various anaerobic infections, often mixed with other aerobic and anaerobic bacteria. P. melaninogenica is an anaerobic, Gram-negative rod, named for its black colonies, and black pigment.
Porphyromonas is a Gram-negative, non-spore-forming, obligately anaerobic and non-motile genus from the family Porphyromonadaceae. There were 16 different Porphyromonas species documented as of 2015, which reside in both animal and human reservoirs. It was discovered more recently that Porphyromonas also exist in the environment, albeit to a lesser extent. This genus is notably implicated in the modulation of oral cavity, respiratory tract, and gastrointestinal tract disease states. It is suggested that Porphyromonas either operate as benign bacteria pertinent to host immunity or are potential pathobionts that opportunistically provoke diseased states when homeostasis is disrupted. Despite its characterization not being fully elucidated due to sparse research, various studies report the prevalence of this genus at 58.7% in healthy states compared with 41.3% in diseased states.
Dialister pneumosintes is a nonfermentative, anaerobic, gram-negative rod that grows with small, circular, transparent, shiny, smooth colonies on blood agar. D. pneumosintes has been recovered from deep periodontal pockets, but little is known about the relationship between the organism and destructive periodontal disease.
Dysgonomonas gadei is a Gram-negative and facultatively anaerobic bacterium from the genus of Dysgonomonas which has been isolated from a gall bladder from a patient in Bergen in Norway.
Porphyromonas catoniae is a Gram-negative and anaerobic bacterium from the genus Porphyromonas which has been isolated from the human gingival crevice.
Porphyromonas circumdentaria is a Gram-negative and anaerobic bacterium from the genus Porphyromonas which has been isolated from a subcutaneous abscess of a cat in Australia.
Porphyromonas gulae is a Gram-negative, anaerobic, non-spore-forming, rod-shaped and non-motile bacterium from the genus Porphyromonas which has been isolated from the gingival sulcus of a wolf in Canada.
Desulfofaba is a Gram-negative, anaerobic, non-spore-forming and motile bacteria genus from the family of Desulfobacteraceae.
Dolosicoccus is a Gram-positive, facultatively anaerobic and non-motile genus of bacteria from the family of Aerococcaceae with one known species.
Marinospirillum minutulum is a helical, halophilic and Gram-negative bacterium from the genus of Marinospirillum.
Clostridium acetireducens is a Gram-positive, rod-shaped, anaerobic and non-motile bacterium from the genus of Clostridium which has been isolated from an anaerobic bioreactor from De Krim in the Netherlands.
Clostridium isatidis is a Gram-positive, anaerobic and moderate thermophilic bacterium from the genus Clostridium.
Catonella is a Gram-negative, obligately anaerobic, non-spore-forming and non-motile bacterial genus from the family of Lachnospiraceae with one known species. Catonella morbi occur in the gingival crevice of humans.
Dorea is a Gram-positive and nonspore-forming bacterial genus from the family Lachnospiraceae, which occur in human faeces.
Dorea formicigenerans is a Gram-positive, obligately anaerobic, non-spore-forming, and rod-shaped bacterium from the genus Dorea and is found in human faeces.
Dorea longicatena is a Gram-positive, obligately anaerobic, non-spore-forming and rod-shaped bacterium from the genus of Dorea which has been isolated from human feces in Germany.
Anaerofilum pentosovorans is a Gram-positive strictly anaerobic, mesophilic and acidogenic bacterium from the genus Anaerofilum which has been isolated from sludge from a bioreactor from Frankfurt in Germany.
Alloprevotella rava is a Gram-negative and anaerobic bacterium from the genus of Alloprevotella which has been isolated from the human oral cavity.
Alloprevotella tannerae is a Gram-negative, obligately anaerobic, non-spore-forming, rod-shaped and non-motile bacterium from the genus of Alloprevotella which has been isolated from a human gingival crevice.
Atopobacter is a Gram-positive, rod-shaped and facultatively anaerobic genus of bacteria from the family of Carnobacteriaceae with one known species. Atopobacter phocae has been isolated from common seals.
