Abstract

Echinococcus vogeli originates neotropical polychistic echinococcosis, an emerging zoonotic disease in tropical countries of Central and South America. Its life cycle is adapted to a mandatory relationship between the bush dog (Speothos venaticus) and one of its main prey, the paca (Cuniculus paca), which is, in turn, one of the most consumed species as a source of animal protein in the Peruvian Amazon. The aim of this work was to evaluate the frequency of E. vogeli in pacas hunted for personal consumption by inhabitants in the high basin of the Itaya River. During 2016-2017, subsistence hunters from the communities of Melitón Carbajal, Luz del Oriente, 28 de Enero and Nueva Villa Belén collected liver and lungs of 36 pacas and the liver of a nine-banded armadillo (Dasypus novemcinctus). These organs were analyzed by parasitological, including macroscopic, microscopic-morphometric analysis. The 13.5% (5/37) of the wild mammals collected (paca n=4; nine-banded armadillo n=1) presented polycystic masses in the liver, with rostral hooks of protocystic scolices compatible with E. vogeli. This work contributes to the ecoepidemiological knowledge of new records on the distribution of E. vogeli and confirms the first record of E. vogeli in the nine-banded armadillo in the Peruvian Amazon, reinforcing the need to raise awareness, prevent, monitor, control and expand the search for neotropical echinococcosis and other zoonoses in wildlife and human populations in coexistence, from the “One Health” approach.
