Infection rates of E. histolytica and E. dispar partitioned by distance from site of initial infection: a) PU, b) AN, c) MK, and d) AK. (For F and p values from ANOVA, see Table 3.) Peaks in infections in both parasites occur at a distance not immediately surrounding the initial infection site in at least two of the four populations – MK and AK. Dark bars are E. dispar infections; light bars rare E. histolytica infections.
