Cladorchis pyriformis (Diesing, 1838) (Digenea, Cladorchiidae): new rodent host and geographic records in Argentina

“…Until now, C. pyriformis has not been found in either of these two hosts (Tapirs and marsh rats) that currently share area in the province of Formosa. Prudhoe (1949) reported C. pyriformis in D. leporina, finding several morphological differences between the specimens found and those of the original description, which was explained as due to the host size. Dasyprocta leporina has a frugivorous diet and inhabits patches of forests within the savannahs and Atlantic lowland forests.…”

“…Cladorchis pyriformis is distinguished from the only other species of the genus, Cladorchis asper (Diesing, 1838), a parasite of Tapir, Tapirus terrestris (Linnaeus, 1758), from Brazil by the absence of papillae on the external surface of the posterior sucker (Prudhoe 1949). It is interesting to note that since 1901, these are the only two species found within this genus, which were reported in Tapiridae, Cricetidae, and Dasyproctidae (Table 2).…”

“…It is interesting to note that since 1901, these are the only two species found within this genus, which were reported in Tapiridae, Cricetidae, and Dasyproctidae (Table 2). In addition, C. pyriformis was reported parasitizing to Agouti, Dasyprocta leporina (Linnaeus, 1758), from Surinam (Prudhoe 1949), Tapirs from Brazil (Travassos et al 1969), and marsh rats, H. vulpinus, from Uruguay and Argentina (Buenos Aires province) (Sutton and Lunaschi 1990). According to Esteban et al (2011), in the life cycle of species of the family Cladorchiidae, cercarial encystment takes place on aquatic vegetation, on the water surface, or even on snail shells.…”

Histological characterization of Sticholecitha serpentis Prudhoe, 1949 (digenea, bieriidae, sticholecithinae), parasite of Bothrops moojeni Hoge, 1966 (serpentes, viperidae)

“…The S. serpentis species was described by Prudhoe (9). In an important systematic review, Skrjabin (14) (4).…”

“…Its occurrence has been reported only in Chironius carinatus Linnaeus, 1758 (9), Xenodon severus Linnaeus, 1758 (5) and Bothrops moojeni Hoge, 1966 (4). This helminth presents a dorsal longitudinal keel that hinders the observation of the internal structures after compression.…”
