Levels of serum IgG (Figure 1 Panel

Levels of serum IgG (Figure 1 Panel A) and serum IgG1 (Figure 1
Panel B) to OV antigen were significantly higher (P,0.001, for both)
in individuals with both lighter (1–499 epg) or heavier ($500 epg)OV
infections compared to EN individuals (no eggs in feces). In addition,
individuals with heavier OV infection had higher levels of serum
IgG1 to OV antigen than individuals with lighter OV infection
(Figure 1 Panel B). Levels of urine IgG were not significantly elevated
in any of the infection groups (Figure 1 Panel D).
