    The plastination technique is a recently developed option to preserve biological tissues widely used in human and veterinary anatomy. This process allows one to obtain real, safe, clean, dry, resistant and permanently stable material without any additional treatment or maintenance. All these advantages are associated with the rapid expansion of plastination during recent decades in a high number of educational institutions. However, the studies of parasite conservation through plastination are scarce, although the material obtained has a high quality, as prior references have shown. In this study, 141 students of veterinary medicine and pharmacy university degrees used, in a blind study, plastinated specimens (experimental group) or wet specimens (control group) during three consecutive practical sessions. Afterwards all the students completed anonymous questionnaires on both knowledge and satisfaction. The results demonstrated that plastinated parasites are a valid and satisfactory alternative to be used as a teaching/learning tool during practical lessons. Moreover, with regard to the knowledge of morphological structures, the results from the questionnaire of assimilated knowledge showed no differences between the use of plastinated and formaldehyde-preserved parasites
