Abstract

Echinococcosis is a zoonotic parasitic illness that can cause significant disabilities, and even death for sick people. The disease is caused by the larval stage of cestodes belonging to the Echinococcus genus. In this study, multiple hydatid cysts were excised from an infected porcine liver. The identification of the parasitic species was made by the morphometric assessment of rostellar hooks and molecular detection of ribosomal DNA extant in protoscoleces of the hydatid sand. Rostellar hooks presented an average length of 27.4 µm by optical microscopy. Parasite DNA were detected in samples of hydatid sediment and positive controls by polymerase chain reaction. In conclusion, Echinococcus granulosus was recognized in samples of porcine hydatid cysts by microscopic observation, and the E. granulosus sensu lato strain E. canadensis G6/G7 was identified by molecular assay.
