Neospora caninum detection test kit by using qPCR. Neospora caninum is responsible for neosporosis, an infectious disease for many canids and cattle. Neuromuscular degeneration in canids, which led to hind limb paralysis, and spontaneous abortion in dairy cattle were observed as major causes of disease by neosporosis. The definitive hosts are domestic dogs, coyotes, grey wolves, and dingos; where the parasite can complete their life cycle. Recent studies have broadened the list of known intermediate hosts to include birds, which can be an important link in the transmission to other animals.
