| ecology of the parasitic endohelminth community of pseudoplatystoma fasciatum (linnaeus, 1776) (siluriformes: pimelodidae) from the aquidauana river, pantanal, state of mato grosso do sul, brazil. | this study investigated the structure and diversity of the endohelminth community and its interactions with pseudoplatystoma fasciatum, caught in the aquidauana river, in the state of mato grosso do sul, brazil. ten helminth species were represented in 1,228 specimens of parasites found in the intestine and mesentery of 33 specimens of p. fasciatum. cestodes were observed in the intestine, while nematodes cucullanus sp. in the mesentery. contracaecum sp. type 1, spatulifer rugosa and choanoscole ... | 2009 | 19347150 |
| metazoan endoparasites diversity of pseudoplatystoma corruscans (siluriformes: pimelodidae) as an indicator of environmental alterations on a tropical aquatic system. | the aim of the present study was to detect the alterations of pseudoplatystoma corruscans parasite infracommunity structure, after the construction of the porto primavera dam on the high paraná river floodplain. the execution of this research was based on 119 host specimens collected between march 2011 and september 2012, and the results were compared to studies performed on periods before the reservoir's construction, when 110 fishes were collected between march 1992 and february 1993. five par ... | 2014 | 25119352 |
| harriscolex nathaliae n. sp. (cestoda: proteocephalidea) from pseudoplatystoma corruscans (siluriformes: pimelodidae) in the paraná river basin, argentina. | the proteocephalidean cestode harriscolex nathaliae n. sp. (proteocephalidae: zygobothriinae) is described from the intestine of the spotted sorubim pseudoplatystoma corruscans (spix and agassiz) (siluriformes: pimelodidae) from the paraná river basin in argentina. this new species differs from the only species of the genus, harriscolex kaparari (woodland, 1935), which is a parasite of pseudoplatystoma tigrinum (linnaeus) from the amazon river in brazil, by its larger scolex (width of 450-750 μm ... | 2013 | 23146094 |
