Parvibacter is a genus in the phylum Actinomycetota containing a single species, Parvibacter caecicola. [1]
In 2018, Nouioui et al. proposed merging the genus Parvibacter along with the genera Asaccharobacter and Enterorhabdus within the genus Aldercreutzia based on observed clustering of these genera within phylogenetic trees. [2] However, subsequent phylogenetic analyses observed that Parvibacter caecicola exhibited much deeper branching compared to other Aldercreutzia species. [1] Its phylogenetic distinctness was further demonstrated by the presence of five conserved signature indels (CSIs) that are exclusively shared by all Aldercreutzia species except for P. caecicola. [1] Thus, P. caecicola was transferred back into the genus Parvibacter, which continues to be a validly published genus.
The Actinomycetota are a diverse phylum of Gram-positive bacteria with high G+C content. They can be terrestrial or aquatic. They are of great economic importance to humans because agriculture and forests depend on their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up anew by plants. While this role is also played by fungi, Actinomycetota are much smaller and likely do not occupy the same ecological niche. In this role the colonies often grow extensive mycelia, like a fungus would, and the name of an important order of the phylum, Actinomycetales, reflects that they were long believed to be fungi. Some soil actinomycetota live symbiotically with the plants whose roots pervade the soil, fixing nitrogen for the plants in exchange for access to some of the plant's saccharides. Other species, such as many members of the genus Mycobacterium, are important pathogens.
The Actinomycetia are a class of bacteria.
The Bifidobacteriaceae are the only family of bacteria in the order Bifidobacteriales. According to the 16S rRNA-based LTP release 106 published by 'The All-Species Living Tree' Project, the order Bifidobacteriales is a clade nested within the suborder Micrococcineae, also the genus Bifidobacterium is paraphyletic to the other genera within the family, i.e. the other genera are nested within Bifidobacterium.
Streptomycetaceae is a family of Actinomycetota, making up the monotypic order Streptomycetales. It includes the important genus Streptomyces. This was the original source of many antibiotics, namely streptomycin, the first antibiotic against tuberculosis.
The Actinomycetaceae are a family of bacteria in the order Actinomycetales that contains the medically important genus Actinomyces. These organisms are closely related to the mycobacteria, but were originally classified as fungi because they were thought to be transitional forms between bacteria and fungi.
The Pseudonocardiaceae are a family of bacteria in the order Actinomycetales and the only member of the suborder Pseudonocardineae.
Adlercreutzia is a genus in the phylum Actinomycetota (Bacteria).
The Glycomycetaceae are a family of bacteria.
"Tropheryma whipplei" is a bacterium that is the causative organism of Whipple's disease, and rarely, endocarditis.
Asaccharobacter is a bacterial genus from the family of Coriobacteriaceae. Up to now there is only one species of this genus known.
Asaccharobacter celatus is a Gram-positive, non-spore-forming and obligately anaerobic bacterium from the genus of Asaccharobacter which has been isolated from a rat caecum in Japan. Asaccharobacter celatus produces equol and 5-hydroxy equol.
Serinicoccus is a Gram-positive, strictly aerobic and moderately halophilic bacterial genus from the family Ornithinimicrobiaceae. The genus was formerly in the family Intrasporangiaceae, but later genomic data caused it to be reclassified in 2018.
Ornithinimicrobium is a Gram-positive, non-spore-forming and non-motile bacterial genus from the family Ornithinimicrobiaceae. The genus was formerly in the family Intrasporangiaceae, but later genomic data caused it to be reclassified in 2018.
The Dermatophilaceae is a Gram-positive family of bacteria placed within the order of Actinomycetales. Dermatophilaceae bacteria occur on animal and human skin and in fish guts.
Knoellia is a genus of Gram positive, aerobic, non-endosporeforming bacteria. Species in this genus are mesophilic and have cells that are irregular rods or coccoid.
Knoellia remsis a species of Gram positive, nonmotile, non-sporeforming bacteria. The bacteria are aerobic and mesophilic, and the cells are coccoid that group in pairs, tetrads, or clusters. It was originally isolated from an air sample from the Regenerative Enclosed Life Support Module Simulator, which was a system designed to simulate life aboard the International Space Station. The species is named after REMS, the acronym for the Regenerative Enclosed Life Support Module Simulator. The species was originally classified as Tetrasphaera remsis in 2007, but was reclassified into the genus Knoellia in 2018.
Ornithinimicrobiaceae is a family of bacteria. It was created in 2018 after a large genome-based study of the Actinobacteria.
The Streptosporangiales are an order of bacteria.
The Micrococcales are an order of bacteria in the phylum Actinomycetota.
The Eggerthellaceae are a family of Gram-positive, rod- or coccus-shaped Actinomycetota. It is the sole family within the order Eggerthellales.
