Calves infected with a sporozoite suspension of the Ikeda strain of Theileria sergenti were examined in attempts to detect the schizont stage. A suspension equivalent to the contents of 70-200 ticks was inoculated subcutaneously into 10 splenectomized calves. Schizonts and micromerozoites were found in the prescapular lymph nodes of 5 calves about 8 days after the sporozoite inoculation. Schizonts detected at the time of nuclear division had large and diffuse nuclei, and many of the schizonts were very large and extracellular in lymph node smears. The schizonts were also detected by the direct fluorescent antibody staining.
