Enterocloster clostridioformis, formerly known as Clostridium clostridioforme, is an anaerobic, motile, Gram-positive bacterium. [2]
E. clostridioformis are rod-shaped bacteria which cannot grow in the presence of oxygen. [3] While Clostridium species have cell walls that resemble gram-positive bacteria, E. clostridioformis often appears negative by Gram stain. [4]
The organism now classified as E. clostridioformis was first identified in the 1950s in human and animal feces and assigned to the genus of Gram-negative non-spore-forming bacteria Bacteroides . [4] In subsequent years, these bacteria were shown to form spores, causing them to be reclassified in the genus Clostridium. [4] Most recently this species has been reclassified as E. clostridioformis based on phylogeny.
Actinobacillus is a genus of Gram-negative, nonmotile and non-spore-forming, oval to rod-shaped bacteria occurring as parasites or pathogens in mammals, birds, and reptiles. It is a member of the family Pasteurellaceae. The bacteria are facultatively anaerobic or aerobic, capable of fermenting carbohydrates, and of reducing nitrates. The genomic DNA contains between 40 and 47 mol % guanine plus cytosine.
Alicyclobacillus is a genus of Gram-variable, rod-shaped, spore-forming bacteria. The bacteria are able to grow in acidic conditions, while the spores are able to survive typical pasteurization procedures.
Thermoanaerobacter is a genus in the phylum Bacillota (Bacteria). Members of this genus are thermophilic and anaerobic, several of them were previously described as Clostridium species and members of the now obsolete genera Acetogenium and Thermobacteroides
Dendrosporobacter is a genus in the phylum Bacillota (Bacteria). Members of the class Negativicutes, stain gram negative, despite being firmicutes
Thermoanaerobacter brockii, formerly Thermoanaerobium brockii, is a thermophilic, anaerobic, spore-forming bacterium.
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.
Bacteriovorax is a genus containing a single species of bacterium in the family Bacteriovoracaceae, Bacteriovorax stolpii. It is a predator that feeds on larger Gram-negative bacteria. These prey bacteria tend to live in enteric environments and have similar lipopolysaccharide structures. Bacteriovorax stolpii recognizes its prey by outer membrane protein receptors, which explains why Gram-positive bacteria that lack outer membranes do not serve as prey. They prey on bacteria by invading the interperiplasmic space where they feed, grow, and reproduce. Bacteriovorax stolpii used to be classified in the genus Bdellovibrio because of similar morphologies and lifestyle characteristics, however they were recognized as a new genus through phylogenetic analysis.
Allofustis is a Gram-positive, rod-shaped, facultatively anaerobic and non-spore-forming bacterial genus from the family of Carnobacteriaceae, with one known species.
Atopococcus is a Gram-positive, non-spore-forming and non-motile bacterial genus from the family of Carnobacteriaceae, with one known species.
Desulfofaba is a Gram-negative, anaerobic, non-spore-forming and motile bacteria genus from the family of Desulfobacteraceae.
Enterocloster aldensis, formerly Clostridium aldenense, is a bacterium in the genus Enterocloster. The type species was isolated from clinical infections in California in the United States along E. citroniae and placed in the genus Clostridium. Together with other gram-negative species, it was moved to the new genus Enterocloster in 2020. The name pertains to R. M. Alden Research Laboratory and its first patron, Rose M. Alden Goldstein.
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.
Mogibacterium is a Gram-positive, strictly anaerobic and non-spore-forming bacterial genus from the family of Eubacteriaceae.
Alicyclobacillus disulfidooxidans a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produced endospores. It was first isolated from waterwater sludge in Blake Lake City, Quebec, Canada. The species was first identified in 1996, but was classified as Sulfobacillus disulfidooxidansis. It was reclassified as Alicyclobacillus in 2005. The name is derived from the Latin duplus (double), sulfur (sulfur), and oxido (oxidize), referring to the bacterium's ability to oxidize disulfide.
Coprothermobacter is a genus of rod-shaped microorganisms, belonging to the new bacterial family Coprothermobacteraceae of the new phylum Coprothermobacterota. This taxonomic genus has been reclassified in 2018, after different phylogenetic studies showed that these bacteria represented a deeply branched taxon of the domain Bacteria; consequently, the clade including this genus has been classified in a separate phylum from Firmicutes, the phylum where it was included before reclassification.
Hungatella effluvii is a Gram-positive, anaerobic and spore-forming bacterium from the genus of Hungatella.
Wukongibacter is a Gram-positive, spore-forming, rod-shaped, anaerobic and non-motile genus of bacteria from the family of Peptostreptococcaceae with one known species.
Pluralibacter is a genus of Gram negative bacteria from the family of Enterobacteriaceae. The genus consists of two species, P. gergoviae and P. pyrinus. Both species were originally classified in the genus Enterobacter, but were reclassified into the novel genus Pluralibacter in 2013.
Terrisporobacter is a genus of Gram-positive spore-forming bacteria in the family Peptostreptococcaceae. Members of this genus were once classified as Clostridium until phylogenetic data revealed it should be a distinct genus.
