Entomoplasmatales is a small order of mollicute bacteria.
The genus Spiroplasma is part of this order.
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [2] and National Center for Biotechnology Information (NCBI) [3]

Acholeplasmataceae is a family of bacteria. It is the only family in the order Acholeplasmatales, placed in the class Mollicutes. The family comprises the genera Acholeplasma and Phytoplasma. Phytoplasma has the candidatus status, because members still could not be cultured.
Acholeplasma are wall-less bacteria in the Mollicutes class. They include saprotrophic or pathogenic species. There are 15 recognised species. The G+C content is low, ranging from 26 - 36% (mol%). The genomes of Acholeplasma species range in size from 1.5 to 1.65 Mbp. Cholesterol is not required for growth. The species are found on animals, and some plants and insects. The optimum growth temperature is 30 to 37 degrees Celsius.
Anaeroplasmatales is an order of mollicute bacteria which are generally found in the rumens of cattle and sheep. The only family in the order is the family Anaeroplasmataceae.
Rubrobacter is a genus of Actinomycetota. It is radiotolerant and may rival Deinococcus radiodurans in this regard.
The Acidobacteriaceae are a family of Acidobacteriota.
The Veillonellaceae are a family of the Clostridia, formerly known as Acidaminococcaceae. Bacteria in this family are grouped together mainly based on genetic studies, which place them among the Bacillota. Supporting this placement, several species are capable of forming endospores. However, they differ from most other Bacillota in having Gram-negative stains. The cell wall composition is peculiar.
The Solirubrobacterales are an order of Actinomycetota.
The Selenomonadales are an order of bacteria within the class Negativicutes; unlike most other members of Bacillota, they are Gram-negative. The phylogeny of this order was initially determined by 16S rRNA comparisons. More recently, molecular markers in the form of conserved signature indels (CSIs) have been found specific for all Selenomonadales species. On the basis of these markers, the Selenomonadales are inclusive of two distinct families, and are no longer the sole order within the Negativicutes. Several CSIs have also been found specific for both families, Sporomusaceae and Selenomonadceae. Samples of bacterial strains within this order have been isolated from the root canals of healthy human teeth.
Entomoplasma is a mollicute bacteria genus. Entomoplasma freundtii can be isolated from the green tiger beetle.
Mesoplasma is a genus of bacteria belonging to the class Mollicutes. Mesoplasma is related to the genus Mycoplasma but differ in several respects.
The Acidimicrobiia are a class of Actinomycetota, in which three families, eight genera, and nine species have been described, Acidimicrobium ferrooxidans is the type species of the order.
Hydrogenobacter is a genus of bacteria, one of the few in the phylum Aquificota. Type species is H. thermophilus. This genus belongs to Bacteria as opposed to the other inhabitants of extreme environments, the Archaea.
Bacteriovoracaceae is a family of gram-negative, comma-shaped bacteria. All members have a two-part life cycle consisting of a free-living motile "attack phase" and a "predatory phase" that lives in the periplasm of other gram-negative bacteria. Bacteriovoracaceae are found in freshwater and in the soil.
Euzebya is a genus of Gram-positive bacteria.
The Rhodothermales are an order of bacteria.
Pirellulales is an order of bacteria.
Pelagicoccus is a Gram-negative genus of bacteria from the family of Puniceicoccaceae.
The Opitutales is an order in the phylum Verrucomicrobiota.
The Opitutaceae are a Gram-negative and chemoheterotrophic order of the domain Bacteria. Opitutaceae bacteria were isolated from soil and coastal marine springs.
Thermosipho is a genus of Gram-negative staining, anaerobic, and mostly thermophilic and hyperthermophilic bacteria in the family Thermotogaceae.
