Mycoplasma ovipneumoniae with population declines in several other wild caprinae, including the Norwegian muskox. "Mycoplasma" species are labile organisms which are easily destroyed by heat, dehydration, sunlight, and common disinfectants, so they do not survive for a long time outside the body of the animal. As of now, and with many "Mycoplasma" diseases, no protective immune responses have been achieved with the use of vaccines, though antibodies can be obtained. <br> Mycoplasma ovipneumoniae Mycoplasma ovipneumoniae is a species of "Mycoplasma" bacteria that most commonly inhabits and affects ovine animals. "M. ovipneumoniae" is a respiratory pathogen of domestic sheep, domestic goats, bighorn sheep,
