    • Indirect via fomites (less frequent).

Pathological effects

  • Diseases caused Mycoplasmosis :
    • Pneumonia Lung: bacterial pneumoniaM. canis has been isolated from pneumonic lungs, but following experimental infection no disease produced.
    • Urinary tract disease CystitisM. canis often isolated in mixed culture along with bacteria.
    • Endometritis/infertility - again M. canis isolated in mixed culture with other pathogens.
    • Colitis Colitis: overviewM. canis occasionally isolated from colonic biopsies from dogs with colitis Colitis: overview.
