Subgroup 1 (n = 21) comprised of Trichuris and/or Ascaris egg positive stool and elevated Ascaris IgE (egg+IgEhi), a typical infection, subgroup 2 (n = 35) consisted of Trichuris and/or Ascaris egg positive stool without elevated Ascaris IgE (egg+IgElo), subgroup 3 (n = 21) contained Trichuris and Ascaris egg negative stool but elevated Ascaris IgE (egg-IgEhi), and subgroup 4 (n = 47) included Trichuris and Ascaris egg negative stool and low Ascaris IgE (egg-IgElo). This evidence concerns the gene IGHE and infection.
