This study was carried out to investigate a case of elk babesiosis in Daegu Korea [R.]. Hematologically, the erythrocyte count was 1.93 million/cu.mm, 11% of which were infected with Babesia. Most (88%) of the protozoa were spherical or vacuolated ring form in shape, resembling B. bovis. The sizes (0.98-2.85) were slightly smaller than the latter. About 7% of the protozoa were vacuolated oval, the size of which varied from 2.06-2.95 x 1.08-1.97 (2.53 x 1.51 in average). The remaining 5% were irregular in shape

This study was conducted to determine variations in the synthesis of DNA in the nuclei of various elements of the golden hamster (Mesocricetus auratus) placenta with increasing gestational age from the 8th day post coitum to parturition. The mitotic activities of the endodermal cells of the visceral yolk sac and of the parietal yolk sac, the trophoblastic cells of the labyrinth and the trophospongium and the giant cells were decreased with increasing gestational age. The placentation was nearly completed by 13 day of pregnancy and the increase in size of labyrinth was by appositional growth from the trophospongial cells
