Abstract: A monkey was infected with sporozoites of Plasmodium cynomolgi from Vietnam.Parasite emia was detected on the 8th day with a starting density of 17/100 white blood cells.22 hours after that time,many EE schizonts appeared with an average density of 3.74±0.66 per mm3 hepatic tissue in liver biopsy specimens from the monkey.Most of the EE schizonts were immature and grew at an uneven rate,having an average diameter of 34.22±7.28μm but some of them even remained 15.75±2.47μm in diameter similar to the EE.schizonts on the 6th day.The results showed that the EE schizonts of Plasmodium cynomolgi were asynchronous in growth.The authors suggest that the release of merozoites from liver might be a successive process for many times,and not to be completed at a time.
