Veterinary bacteriology: information about important bacteria
|Species/Subspecies:||Mycoplasma capricolum subsp. capricolum|
|Etymology:||Genus name: fungus shaped.|
Species epithet: exists in the goat (the ram).
Subspecies epithet: see
|Significance:||Has been reported from Africa, Australia, Europe (not Sweden) and USA.
[Of minor importance]
|Type Strain:||California kid = ATCC 27343|
|Macromorphology (smell):||Forms small and very typical umbonated colonies ("fried egg appearance), which can be observed in a microscope.|
|Micromorphology:||Very small and pleomorphic. Non-motile.|
|Gram +/Gram -:||G-, but is normally not gram stained because the cells will then be fragmented.|
|Metabolism:||Facultatively anaerobic. Energy source: glucose (pH is decreased).|
|Other Enzymes:||Urease -|
|Fermentation of carbohydrates:||Glucose +|
|Disease:||Mastitis, pneumonia, polyarthritis, septicaemia.
|16S rRNA Seq.:|
||Seven species have been described within the revised genus Mycoplasma to which Mycoplasma capricolum subsp. capricolum belongs. Two of these species are divided into four subspecies. These species and subspecies belong to the so-called the mycoides group and they are closely related to mollicutes within the genus Spiroplasma. This genus contains many plant pathogens. See the phylogenetic tree (Fig. 119:1). Note that it is only for the mollicutes of the mycoides group that the letter M stands for Mycoplasma. For the other species, M means: 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. For some mollicutes (mycoplasmas) the names have not changed and this applies to members of the mycoides group. 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.Published 2023-03-01. Read more...
|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 VetBactPublished 2023-03-15. Read more...
