The burden of pathogenic enteric protozoa and soil-transmitted helminths among impoverished populations living on the Texas–Mexico border is unclear. We conducted a cross-sectional study on an ongoing longitudinal cohort of 616 adults residing in Starr County, Texas. A total of 359 adults were screened for four protozoa and five soil-transmitted helminths by using real-time polymerase chain reaction. This analysis identified 48 (13.4%) participants who tested positive for Blastocystis sp., three (0.8%) who tested positive for Giardia intestinalis, and one (0.3%) who tested positive for Strongyloides stercoralis and was also coinfected with Blastocystis sp. Infection was significantly associated with age, a lack of health insurance, and living outside of a colonia. We recommend additional epidemiologic investigations to examine risk factors contributing to protozoa and soil-transmitted helminth disease transmission in border counties.
