Resumen:
First report of Echinococcus vogeli in a paca in Misiones province, Argentina
Abstract
We report the fi rst fi nding of Echinococcus vogeli in a paca, Cuniculus paca, in the tropical
forest of Misiones, in the north of Argentina. The presence of the bush dog, Speothos
venaticus, E. vogeli´s only natural defi nitive host, was also reported. The polycystic
hydatids, 2 to 3 cm in diameter, were only found in the liver of an adult paca. The size
range of the hooks and the relative proportion blade/handle did not show signifi cant
differences with respect to the ones reported for E. vogeli. The size of E. granulosus
hooks, measured for comparison purposes, was signifi cantly smaller (p < 0.0001). These
results confi rmed the presence of E. vogeli in Argentina. The probability of fi nding
neotropical echinococcosis in humans reinforces the need to expand the search for
E. vogeli in Argentina. Echinococcosis due to E. vogeli is very aggressive and may cause
death in about a third of the human population affected
