To the Editor—We report supplemental findings incorporating Toxoplasma gondii serology results from our study of risk factors for Toxocara seropositivity in the United States [1] using stored serum samples collected from the National Health and Nutrition Examination Survey (NHANES), 2011–2014. Whereas T. gondii is a protozoan parasite and Toxocara is an intestinal nematode, both share ingestion of contaminated soil as means of exposure in humans. Both parasites can contaminate soil when environmentally resistant T. gondii oocysts or Toxocara cati eggs are shed in the feces of infected cats [2, 3].
