Species/Subspecies: Mycoplasmopsis felis
Category: In the normal flora
Etymology: Genus name: similar to mycoplasma (fungus shaped).
Species epithet: of cat.
Significance:  [Important]   
Alternative Species Name(s):Mycoplasma felis
Type Strain: CO = ATCC 23391 = NCTC 10160.
Macromorphology (smell):
Forms small and typical umbonated colonies ("fried egg appearance"), which can be observed in a microscope.
Micromorphology: Small coccoid to filamentous.
Gram +/Gram -:G-, but is normally not gram stained because the cells will then be fragmented.
Metabolism: Energy source: glucose (pH is decreased).
Spec. Char.: Lacks a cell wall.
HostsDiseaseClinical picture

Mycoplasmopsis is the largest genus among mollicutes of veterinary importance and about 55 species have been described so far within this genus. M. felis is closely related to M. cynos and M. synoviae. See the phylogenetic tree (Fig. 178:2) where M can mean Mycoplasma, Mesomycoplasma, Metamycoplasma, Mycoplasmoides or Mycoplasmopsis.
Comment:Based on whole genome sequencing, the taxonomy of mycoplasmas has recently undergone a comprehensive revision. The new taxonomy has now been introduced in VetBact, but it will still be possible to search for the alternative species names. Read more about the revised taxonomy of the mollicutes under the Term list of VetBact and see also reference 164 below.

New names of bacterial phyla

The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota.

The taxonomy of chlamydias

Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBact
