In this paper, we report an unusual mixed infection of <jats:italic>Echinococcus vogeli<\/jats:italic> Rausch &amp; Bernstein, 1972 and <jats:italic>Calodium hepaticum<\/jats:italic> (syn. <jats:italic>Capillaria hepatica<\/jats:italic> Bancroft, 1863) in free-ranging paca from a forested region in Acre (Brazil). Gross morphological examination revealed that paca liver contained multiple spherical to subspherical white or translucent lesions, which were isolated or frequently contiguous and partially covered by Glisson's capsule. Microscopic examination revealed unilocular cystic structures that contained abundant brood capsules in which numerous protoscolices budded from the inner surface. The protoscolices possessed rostellar hooks (33\u201341\u00a0<jats:roman>\u03bc<\/jats:roman>m in length), a morphological characteristic of the blade and calcareous corpuscles that is consistent with the metacestode <jats:italic>E. vogeli<\/jats:italic>. The diagnosis of <jats:italic>C. hepaticum<\/jats:italic> infection was based on the morphology and morphometry of the egg-shaped ellipsoids with bipolar plugs (44.8\u00a0\u00b1\u00a01.9\u00a0<jats:roman>\u03bc<\/jats:roman>m (length)\u00a0\u00d7\u00a024.4\u00a0\u00b1\u00a02.0\u00a0<jats:roman>\u03bc<\/jats:roman>m (width)) and liver histopathology. This finding expands the known range of <jats:italic>C. hepaticum<\/jats:italic> hosts in South America and, to the best of our knowledge, it is the first case of a mixed infection of <jats:italic>E. vogeli<\/jats:italic> and <jats:italic>C. hepaticum<\/jats:italic>. Furthermore, our data provide evidence that wild animal meat may be a source of <jats:italic>C. hepaticum<\/jats:italic> infection.<\/jats:p>","DOI":"10.1017\/s0022149x12000661","type":"journal-article","created":{"date-parts":[[2012,10,17]],"date-time":"2012-10-17T09:18:55Z","timestamp":1350465535000},"page":"489-493","source":"Crossref","is-referenced-by-count":14,"title":["Co-infections
