Morphological characterization of fluke eggs in green turtles (Chelonia mydas) found on the coast of Espírito Santo State, Brazil. Cienc. mar [online]. 2022, vol.48, e3211.  Epub 17-Nov-2023.

Although some studies have identified parasites in green turtles (Chelonia mydas), little is known about the morphology of helminth eggs in the feces of these animals. The aim of this study was to morphologically characterize helminth eggs recovered in coproparasitological exams by sedimentation and to analyze their relationship with helminth species recovered during necropsy of juvenile specimens of C. mydas. Four different egg morphotypes were found, identified, and classified as digenetic trematodes of the families Microscaphidiidae, Cladorchiidae, and Spirorchiidae. There was morphological diversity in the size of the eggs measured directly in adult parasites, with sizes ranging from 19.07 to 99.28 μm in length and from 11.35 to 45.66 μm in width. The observation of eggs on coproparasitological exams is important for studying the ecology of sea turtle parasites, since the life cycle of some species is not yet fully understood.
