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,
Alternatives to animal testing performed on intact animals, the maintenance of cells in culture normally requires the use of animal-derived serum. Although exact figures are difficult to obtain, some have estimated that one million fetal cows are sacrificed each year to obtain the world's supply of fetal bovine serum, used to grow cultured cells. Skin irritation and skin corrosion refer to localized toxic effects resulting from a topical exposure of the skin to a substance. Human skin equivalent tests can be used to replace animal-based corrosive and irritative studies. EpiDerm from Mattek and EpiSkin and SkinEthic RHE model are derived from human skin cells
