Abstract

Se recuperaron tres especies de digeneos, incluyendo un gorgoderidae (Plesiochorus cymbiformis) de la vejiga urinaria, un plagiorchiidae (Enodiotrema megachondrus) del duodeno y un pachypsolidae (Pachypsolus irroratus) del estómago, de dos de tres tortugas golfinas (Lepidochelys olivacea) varadas a lo largo de la costa del Pacífico de Costa Rica. Todos los trematodos representan nuevos registros de localidad. Se describieron cambios histopatológicos asociados con huevos de duelas cardiovasculares (Digenea, Spirorchiidae) en los pulmones, el bazo y el intestino de una sola tortuga.Three species of digeneans including 1 Gorgoderidae (Plesiochorus cymbiformis) from the urinary bladder, 1 Plagiorchiidae (Enodiotrema megachondrus) from the duodenum, and 1 Pachypsolidae (Pachypsolus irroratus) from the stomach were recovered from 2 of 3 olive ridley turtles (Lepidochelys olivacea) found stranded along the Pacific coast of Costa Rica.
