Figure 2.

Individual eosinophil counts (mm³) in different S. mansoni infection groups (A). Groups were classified according to their individual egg counts by six Kato-Katz slides into median to high (≥100 epg) or low (4 to 99 epg) parasite load, or into <4 epg, according to more sensitive, qualitative detection methods. The dotted red line indicates the limit of normal eosinophil counts in clinical samples (range 0–500 mm³). Association between peripheral blood eosinophil counts and egg counts per gram of feces, as determined by Kato-Katz (B).
