Abstract
Plastination is a preservation method for biological specimens, with important advantages over classic conservation tech niques with formaldehyde or alcohol. Plastinated specimens are dry, odourless, and free of carcinogenic and toxic solutions. There are only few references about the plastination of parasites. Moreover, there is no information on the effect of plastination on the morphology and morphometry of these animals. The aim of this study was to define a plastination protocol to preserve various species of parasites, namely the nematodes Parascaris equorum (Goeze, 1782); Ascaris suum Goeze, 1782 and Dirofilaria immitis (Leidy, 1856);
the acanthecephalan Macracanthorhynchus hirudinaceus (Pallas, 1781); the trematodes Fasciola hepatica Linnaeus, 1758 and Dicrocoelium dendriticum (Rudolphi, 1819) and the tapeworm Taenia sp. in the best morphological and morphometric conditions. Results showed that some individuals suffered collapse (P. equorum, A. suum, and D. dendriticum). However, other parasites presented good results with almost no change after plastination (D. immitis, M. hirudinaceus and F. hepatica). In conclusion, conventional plastination allowed anatomical preservation of all helminths tested, but modifications to the protocol are needed to prevent collapse.
