High parasite burden was associated with diarrhea due to Entamoeba histolytica (A) but not Entamoeba bangladeshi (B) and Entamoeba dispar (C). The y-axes indicate threshold values of quantitative polymerase chain reaction analyses positive for each parasite. Horizontal lines indicate mean values, and vertical lines indicate standard deviations. **P ≤ .0072, by the Mann-Whitney test. Cq, cycle value at which the (baseline-corrected) amplification curve exceeds the background fluorescence; NS, not significant.
