Principal components analysis (PCA). Each plot shows scores for PCA factor 1 versus factor 2 derived from the mensural data from 2205 individual trypanosomes, each represented by a coloured dot. A. Sequential plots of proventricular trypanosomes (black dots) compared with all other trypanosomes (grey dots). B. Comparison of bloodstream forms (red dots), midgut, proboscis and cibarium trypomastigotes (grey dots), epimastigotes (green dots), and metacyclics (blue dots). C. Comparison of trypanosomes from the proboscis and cibarium.
