Portions of the placenta and kidneys from a 5-month-old bovine fetus were examined histologically. The placental cotyledonary villi were necrotic and protozoa were found in lesions. The organisms were in trophoblasts, periodic acid Schiff-negative and did not react in an immunoperoxidase test using anti-Toxoplasma gondii serum. Individual zoites were ∼ 5×2 μm and the biggest collection was 45 × 35 μm. The organism in the present case was structurally distinct from Sarcocystis spp. and Toxoplasma gondii, but resembled Neospora caninum.
