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 Medical Experiments that despite the use of microdosing, "animal studies will still be required". Guiding principles for more ethical use of animals in testing are the Three Rs (3Rs) first described by Russell and Burch in 1959. These principles are now followed in many testing establishments worldwide. Cell culture can be an alternative to animal use in some cases. For example, cultured cells have been developed to create monoclonal antibodies; prior to this, production required animals to undergo a procedure likely to cause pain and distress. However, even though cell or tissue culture methods may reduce the number of experiments
