The aim of the present study was to provide a current survey of the species of parasites found in the Upper Paraná River floodplain, as well as to investigate which strategies and mechanisms used by parasites, are favored and which environmental factors influence the parasite community in the studied environments. During a seven-year period from February(More)
We examined 44 specimens of Metynnis lippincottianus (Cope, 1870) (Characidae), collected in the Upper Paraná River floodplain, Brazil, from March 2006 to December 2007. Of the total number of fishes, 32 (72.7 %) were infected by at least one species of helminth (endoparasites). One digenean, Dadayus pacupeva, and four nematode species, Spinoxyuris(More)
In order to examine the ecological relationships of metazoan parasites and their hosts, 63 specimens of Steindachnerina brevipinna have been collected from April to September 2006, in the rivers Guairacá and Corvo, tributaries of the low Paranapanema River. Five different parasite species have been found (Paranaella sp., Sphicterodiplostomum musculosum,(More)
Austrodiplostomum compactum (Platyhelminthes, Digenea) eye flukes of several species of fishes. The presence of this parasite, in extreme cases, can cause swelling of the eyelids, displacement of the retina, opacity of the crystalline lens and blindness or even death. The present study it registers new occurrences of this metacercariae infecting the eyes of(More)
The study analyzed 84 specimens of Metynnis lippincottianus (Cope, 1870) (Characidae) from two environments with different degrees of impact due to a hydroeletric plant; 44 hosts from the upper Parana river floodplain (low degree of impact) and 40 from Paranapanema tributaries (Corvo and Guairacá rivers, high degree of impact). The prevalence found, among(More)
Paranaella luquei is a monogenean from family Microcotylidae, which was found parasitizing the gills of Steindachnerina brevipinna (Eigenmann & Eigenmann, 1889), collected in two different tributaries of Paranapanema River, Paraná, Brazil. This parasite was the first species of Microcotylidae described parasitizing freshwater fishes (Hypostomus sp.,(More)
