Figure 1. — Children with fecal anti-Entamoeba histolytica Gal/GalNAc lectin immunoglobulin A (IgA) had a lower rate of reinfection. The y-axis denotes the percentage of children with an E. histolytica infection (n = 307), and the x-axis denotes the interval between the first and second E. histolytica infections. A statistically significant increase in the time to reinfection was observed for children who were fecal IgA anti-lectin positive (red line), compared with those who were negative (black line; P = .0175, by the log-rank [Mantel–Cox] test). A total 65 children tested positive and 242 tested negative for E. histolytica IgA.
