“…Thus, these two species may overlap during the flood season. Paraspidodera uncinata is a parasite of the large intestine of Cavia porcellus, C. aperea and C. fulgida and has been found infecting caviomorph rodents of the families Cavidae and Agoutidae (Travassos & Freitas, 1948;Pinto et al, 2002). Moreover, it has also been reported infecting lagomorphs (Vicente et al, 1997), demonstrating that it has little vertebrate host specificity.…”

Variation in the helminth community structure ofThrichomys pachyurus(Rodentia: Echimyidae) in two sub-regions of the Brazilian Pantanal: the effects of land use and seasonality

et al. 2009

The Pantanal is a large ecosystem located in South America. This preserved area is seasonally flooded due to abundant rainfall during the summer and the subsequent overflow of the Paraguai River. In this paper, we examine the helminth community structure in the wild rodent Thrichomys pachyurus during the wet and dry seasons in two locations of the preserved and cattle ranching areas in the Southern Pantanal. We identified 12 species of helminth, and, although we did not find any differences in species richness between locations within the Pantanal, we found that richness was higher during the wet season. Helminth species were largely aggregated in both farm locations and during seasons. The most common helminth species were more abundant during the dry season than during the wet season, which may have been due to the increased habitat availability and rodent population increase. The intensity of the infection also followed the same pattern for most helminths. The trichostrongylids (Heligmostrongylus crucifer, H. almeidai and Pudica cercomysi) were dominant at both farm locations. The land use of each area was not correlated with helminth diversity. However, species composition of the helminth community of T. pachyurus differed between locations and may be correlated with environmental differences between the habitats. The seasonality of the Pantanal was highly correlated with helminth parasitism in T. pachyurus.

Species of fish of Marajó Island, State of Pará, Brazil, were examined to identify the trematodes parasitizing 102 Hoplerytrinus unitaeniatus (gold wolf fish) and 104 Hoplias malabaricus (thraira). Metacercariae of two species of trematodes, 170 specimens of Clinostomatopsis sorbens and 10 Ithyoclinostomum dimorphum were found and identified. The parasitary indices of C. sorbens from H. unitaeniatus and H. malabaricus, were 43.14% and 30.77% for prevalence, 2.52 and 1.84 for mean intensity, 1.09 and 0.57 for mean abundance and 1 to 9 and 1 to 7 for range of infection, respectively, on both fish the site of infection was the mesentery. The parasitary indices of I. dimorphum from H. unitaeniatus were 2.94% for prevalence, 2.66 for mean intensity, 0.08 for mean abundance, 1 to 4 for range of infection, and the sites of infection were the mesentery and the muscle. Metacercariae of I. dimorphum were collected in muscles of a specimen of H. malabaricus, with 0.96% of prevalence, intensity of infection of 2 parasites and 0.02 of abundance. New morphological data of external and internal structures are presented. This is the first record of metacercariae of C. sorbens and I. dimorphum in Amazonian fish.

“…by TRAVASSOS (1945) in D. leporina, from the Rio Itaúnas valley, State of Espírito Santo and by TRAVASSOS & FREITAS (1948), in D. leporina and A. paca from Sooretama, State of Espírito Santo, Brazil. Nevertheless, the only available morphometric data on the species are those of HALL (1916) and LÓPEZ-NEYRA (1951) that reproduced data after MOLIN (1859) when P. mediospiralis was described as Spiroptera mediospiralis; the length of males was of 26-36 long, 0.4 wide and that of females 40-46 long, 0.5 wide.…”
