Neospora caninum a Principal Abortifacient Parasite of cattle

Neospora caninum is a protozoan parasite of canines and responsible for neuromuscular paralysis in them. It was firstly recognized as new genus in 1984 earlier than that it was mistaken for Toxoplasma gondii aside from host differences i.e. toxoplasmosis causes abortion in sheep while Neospora caninum in cattle population. Neosporosis is a major cause of abortion in cattle in many countries and according to estimates, the annual cost of N. caninum infections and abortions ranges from a median of US $1.1 million in the beef business in New Zealand to an estimated median impact of US $546.3 million in the US dairy population. In 1988, infections emerged as major global health concern for both dogs and cattle. Abortions and neonatal mortality are two major problems faced by livestock industry due to infection of protozoan. In Humans serum antibodies are found but parasite was not detected. Thus zoonotic transmission of disease is not clear for now
