Biología heart cells cell culture Trypanosomatidae Trypanosoma cruzi In vitro growth kinetics of two Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) clonesin myocardial cells from rodents of different susceptibility. Two Trypanosoma cruzi isolates, TCR-4 fromCosta Rica and UES-1 from El Salvador, were studied in vitro to compare their infectivity or resistance andintracellular replication in myocardial cells in three strains of mice and rats: NGP white mice, C3 H mice andSprague Dowley rats. Myocardial cells were cultured on coverslips at 37 º C in a humid 10 % CO2 atmosphereand then infected at a ratio of one tripomastigote per cell. Samples were studied after 24, 72, 96 and 120 h ofinfection to determine parasite infection capacity and intracellular multiplication. Both parasites had the highestinfection capacity in C3 H mice, followed by NGP mice cells with a very low infection rate. Lastly, almost noTrypanosoma cruzi multiplication was observed in Sprague Dowley rats, suggesting a strong natural resistancein this animal to both strains of the parasite. The UES-1 isolate presented higher multiplication and greater invasionthan the TCR-4 strain, showing greater virulence of UES-1 in heart cells, at least in vitro. Rev. Biol. Trop.55 (1): 121-126.
