Veterinary bacteriology


Species/Subspecies: Mycoplasma bovis
Etymology: Genus name: fungus shaped.
Species epithet: of the ox.
Significance:  [Very important]   
Taxonomy:
Phylum
Tenericutes
Class
Mollicutes
Order
Mycoplasmatales
Family
Mycoplasmataceae 
Genus
Mycoplasma
Type Strain: Donetta = ATCC 25523 = NCTC 10131.
Macromorphology (smell):
   
Forms small and very typical umbonated colonies ("fried egg appearance"), which can be observed in a microscope.
Micromorphology: Very small and pleomorphic
Gram +/Gram -:G-, but is normally not gram stained because the cells will then be fragmented.
Metabolism: Facultatively anaerobic. Does not ferment glucose and does not hydrolyze arginine. M. bovis utilizes organic acids och alcohols as energy sources.
Catalase/Oxidase:
Other Enzymes: Urease -
Spec. Char.: Lacks a cell wall.
Disease:Pneumonia (primarily in calves), mastitis, arthritis
Hosts: Cattle
Clinical Picture: Mastitis caused by M. bovis can be subclinical or very severe. It is often associated with loss of milk production and purulent or serous udder exudate.
Genome Sequence:
Acc-noStrainSize (bp)Genome
CP002188 DonettaT 1 003 404 1c + 1c 
Three strains have been sequenced and one plasmid has been found in all three strains

16S rRNA Seq.:
Acc-noStrainNumber of NTOperon
U02968 DonettaT 1 519 

Taxonomy/phylogeny:
 
About 125 species have been described within the genus Mycoplasma. M. bovis belongs to the hominis group and is very closely related to M. agalactiae.
Comment:Note that the mycoplasmas have recently been transferred to a new phylum, Tenericutes.
