Human gnathostomiasis is one of the important food-borne parasitic zoonoses. The disease is caused by a spirurid roundworm of the genus . Here, we describe three parasitological confirmed cases of human gnathostomiasis, caused by , in a hospital in Thailand during 2004–2012. Clinical characteristics, treatment, and outcome of cases were revealed. Parasites were accidentally recovered from patients and morphologically identified as species. Confirmed diagnosis and identification of causative parasite species was made by DNA extraction of the recovered worms, followed by a polymerase chain reaction (PCR) of the second internal transcribed spacer region (ITS2) of DNA and the partial cytochrome c oxidase subunit 1 () gene. Sequences corresponding to ITS2 and were similar to . To our knowledge, this study represents the first molecular confirmation that recovered is a causative agent of human infection in Thailand.
