The Xavante Indians of the Brazilian state of Mato Grosso as a group were found to have 1) high mean plasma uric-acid levels, 2) low mean plasma cholesterol values, 3) high total plasma proteins, due to elevated γ-globulin fractions, 4) plasma-protein-bound iodines and iron values within the accepted norms, 5) a high frequency of persons with positive tests for the “rheumatoid factor,” 6) marked eosinophilia, and 7) a high frequency of stools positive for the ova of Ascaris, larvae of Strongyloides, and cysts of Entamoeba histolytica. Three of 53 “casual” urine specimens subjected to chromatography were characterized by elevations in specific amino acids, possibly indicative of a genetic carrier status.
