abstract：:Neospora caninum is a recently identified coccidian parasite which shares many features with, but is clearly distinct from, Toxoplasma gondii. N. caninum tachyzoites infect a wide range of mammalian cells both in vivo and in vitro. The mechanisms by which infection is achieved are largely unknown. Recent evidence has ...
