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,
Animal testing medical achievement in the 20th century relied on the use of animals in some way. The Institute for Laboratory Animal Research of the United States National Academy of Sciences has argued that animal research cannot be replaced by even sophisticated computer models, which are unable to deal with the extremely complex interactions between molecules, cells, tissues, organs, organisms and the environment. Animal rights organizations—such as PETA and BUAV—question the need for and legitimacy of animal testing, arguing that it is cruel and poorly regulated, that medical progress is actually held back by misleading animal models that cannot reliably predict effects
