Fig. 6: complement resistance during prolonged starvation of Trypanosoma cruzi epimastigote culture. Percentages of PI-positive parasites representing non-viable cells of the parasite populations from the prolonged starvation of T. cruzi epimastigote culture at day 7 (exponential phase), day 14 (early stationary phase), day 21 (intermediate stationary phase) and day 28 (final of the stationary phase) after incubation with human serum that had or had not been heat treated. At least three independent experiments were performed for each point analysed. Significant differences are indicated: ** = p < 0.01, *** = p <0.001.
