Abstract

Trematode Clinostomum complanatum Rudolphi 1814 is a common helminth of fish-eating birds and is widespread worldwide. Larvae of this parasite live in freshwater fish. Clinostomiasis cases are rare but can occur in people who eat thermally untreated freshwater fish. We describe a case of clinostomosis in a resident of the Tambov region in Russia. The first signs of the disease developed on day 3 after eating river fish (perch). In the next 2 days, the symptoms intensified. After examination of the oropharynx, five species of C. complanatum were removed, and the patient recovered.
