In order to establish a useful cell culture system for T gondii we compared the degree of proliferation of T gondii tachyzoites among 8 different cell lines: 2 kinds of normal animal cells (MDCK-canine kidney cells; Vero-monkey kidney cells) and 6 kinds of human tumor cells (A 549, PC 14-lung cancer cells; SNU 1, SNU 16. Mlm 45-stomach cancer cells; HL-60-promyelocytic leukemia cells), through morphological observation and 3H-uracil uptake assay. The degree of susceptibility to infection with T gondii tachyzoites was highest in A 549 and PC 14 cells, medium in Vero, HL-60, MDCK and SNU 1, and lowest in SNU 16 and MBm 45 cells. The kinetics of T gondii multiplication during the post-Infection 60 hours were higllly dependent upon the dose of tachyzoites administered and the duration among the 8 tested fur the growth and multiplication of T gondii in vitro.
