The gastrointestinal tracts of 72 Osteopilus septentrionalis were examined for helminths. Five nematode species were present: Oswaldocruzia lenteixeirai, Parapharyngodon osteopili, Physalopleroides bahamensis, an unidentified female strongylid, and an unidentified larval oxyurid. Physalopteroides bahamensis had the greatest prevalence (83%) and highest mean intensity (8.4). This represents the first report of O. lenteixeirai and P. osteopili in the Bahamas.
