Mycoplasmatota is a phylum of bacteria that contains the class Mollicutes. The phylum was originally named "Tenericutes" (tener cutis: soft skin). [5] [4] [6] Notable genera include Mycoplasma , Spiroplasma , Ureaplasma , and Candidatus Phytoplasma. [7] Moreover, it lacks a cell wall, its cells and genome sizes are small, and has a low guanine plus cytosine ratio. Due to being one of the smallest bacteria, animals are prone to a disease without showing any type of symptoms, thus serving as carriers and ultimately contribution to the spread of disease.
This phylum was first published as Tenericutes by Murray in a 1984 version of Bergey's Manual. It was republished in 2021 by Oren and Garrity under the revised Prokaryotic Code.
This phylum is not phylogenetically sound: it branches within Bacillota in phylogenomic and 16S analyses. [8] See also Mollicutes § The phylum for Mollicutes.
