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… Expand
Ithyoclinostomum Dimorphum Diesing, 1850 (Digenea, Clinostomidae) in Hoplias Malabaricus (Erythrinidae) with the First Report of Infection of the Eyes
This was the first report of I. dimorphum in the eyes of Hoplias malabaricus, a secondary intermediate host for this endoparasite and the low parasitism did not affect the condition factor (Kn) of the parasitized fish. Expand
Biodiversity of parasites found in the trahira, Hoplias malabaricus (Bloch, 1794), collected in the Batalha River, Tietê-Batalha drainage basin, SP, Brazil.
The findings from this study represent new records of occurrence of H. malabaricus, as well as of Urocleidoides margolisi, Scleroductus sp. Expand
Digenea of Hoplias intermedius and Hoplias malabaricus (Actinopterygii, Erythrinidae) from upper São Francisco River, Brazil.
The presence of metacercariae and adult digeneans indicate that they act as intermediate and definitive hosts, respectively, in their biological cycles, as a result of piscivorous feeding habits of these adult erythrinids from the upper São Francisco River. Expand
Morphological and molecular characterization of an enigmatic clinostomid trematode (Digenea: Clinostomidae) parasitic as metacercariae in the body cavity of freshwater fishes (Cichlidae) across Middle America.
The family Clinostomidae Lühe, 1901 contains 29 species allocated to seven genera, of which Clinostomum Leidy, 1856 is the most diverse, with c. 14 valid species. The diversity of Clinostomum hasExpand

This study compared the parasite communities of Hoplias malabaricus and Hoplerythrinus unitaeniatus from Amazon river system and found that both communities were characterized by low species diversity, low evenness and low richness, and by a high prevalence of ectoparasites. Expand
Ithyoclinostomum yamagutii n. sp. (Digenea: Clinostomidae) in the great blue heron Ardea herodias L. (Aves: Ardeidae) from Mississippi, USA
Using morphological and molecular data these adult specimens were confirmed as conspecific with the larval metacercariae previously described from Central America and Mexico and represent the novel species, Ithyoclinostomum yamagutii n. Expand
Topography Of The Metacercaria Of Edible Fish Channa Punctatus (Bloch) From Ramganga River Moradabad, U.P, India.
In this investigation the liver of host was found highly infected with eggs of trematode and unidentified DTM which is characterized by a complicated morphology of its integument, body and suckers which may be helpful in taxonomical study of parasite. Expand


The life cycle of Clinostomum complanatum Rudolphi, 1814 (Digenea, Clinostomidae) on the floodplain of the high Paraná river, Brazil
The floodplain of the high Paraná river has suitable conditions for the maintenance of the life cycle of C. complanatum, and the high prevalences in birds, especially in A. cocoi, suggest some kind of mechanism facilitating the predation of infected fish. Expand
Nematodes in Hoplerytrinus unitaeniatus, Hoplias malabaricus and Pygocentrus nattereri (pisces characiformes) in Marajó Island, Brazil.
Nematodes with zoonotic potential that were found with high prevalence, shows the importance of actions by the health authorities. Expand
Ecology of Clinostomum complanatum Rudolphi, 1814 (Trematoda: Clinostomidae) infecting fish from the floodplain of the high Paraná River, Brazil
A cumulative effect of repeated infections is observed; for the two other species, the highest parasitised fish may have higher predation mortality rates, and while H. littorale is the preferred item in birds’ diet, L. platymetopon is the most abundant fish species and has the highest C. complanatum prevalence.

Structure and diversity of endoparasitic infracommunities and the trophic level of Pseudoplatystoma corruscans and Schizodon borelli (Osteichthyes) of the high Paraná River.
Independence of diversity values in relation to sex of P. corruscans and S. borelli evidences that the ecological relationships are similar between males and females in these species, indicating that each one presents homogeneity in alimentary behaviour during all its life time. Expand
Revision of the Neotropical trahiras of the Hoplias lacerdae species-group (Ostariophysi: Characiformes: Erythrinidae) with descriptions of two new species
The Hoplias lacerdae group is defined as containing generally large trahiras with the medial margins of dentaries running parallel to each other and lacking teeth on the basihyal compared to the H. malabaricus group in which the medial margin of the dentaries converge towards the mandibular symphysis.

Scanning electron microscopy of Ithyoclinostomum dimorphum (Trematoda: Clinostomidae), a parasite of Ardea cocoi (Aves: Ardeidae)
Scanning electron microscopy is used for the first time to study the surface topography of Ithyoclinostomum dimorphum (Diesing, 1850), collected from Ardea cocoi Linnaeus, 1766 on the floodplain of the upper Paraná River Basin, Brazil, and speculate on the functional significance of some of the findings.

Metazoários parasitos de seis espécies de peixes do Reservatório de Lajes, Estado do Rio de Janeiro, Brasil
The parasite communities of the studied fishes showed scarcity of significant correlations of parasitic abundance, species richness and diversity with the size of the host, and could be originated by the oligotrophic characteristics of the Lajes Reservoir. Expand
Prevalence and pathology of helminths of ciconiiform birds from the Brazilian swamplands.
The prevalence of helminths recovered from 108 birds representing eight species of Ciconiiformes from the Brazilian west-central region are presented and reports of accidental human infections, with severe clinical signs induced by these parasites, indicate the necessity of a proper evaluation of the pathogenicity of helmineths of aquatic birds. Expand
The objectives of the survey were to determine the preferably location of the parasite in the host, relate the season with the higher prevalence and identify them at the level of genus and when possible indicate the species. Expand
New host and geographical records for helminths parasites of Ardeidae (Aves, Ciconiiformes) in Brazil
One thousand two-hundred-four helminth samples recovered from Brazilian Ardeidae birds during 54 years were studied, and 49 new host and three new geographical distribution records were established. Expand
