Eiras,Jorge C.; Monteiro,Cassandra M.; Brasil-Sato,Marilia C.Myxobolus franciscoi sp. nov. (Myxozoa: Myxosporea: Myxobolidae) is described from the "curimatá-pacú" fish, Prochilodus argenteus Spix & Agassiz, 1829 (Actinopterygii: Prochilodontidae) from the Upper São Francisco River, Brazil. This parasite forms whitish plasmodia (about 1 x 1 mm) that develop in the connective tissue of fins. The spores are more or less round in frontal view and ellipsoidal in lateral ...
Habitat selection and maturation of Saccocoelioides nanii (Digenea: Haploporida...
Monteiro,Cassandra M.; Brasil-Sato,Marilia C.This work examined the possible preference of Saccocoelioides nanii Szidat, 1954 for the three major intestinal portions of Prochilodus argenteus Agassiz, 1829 and statistically evaluated whether the river water level dynamic interfered in the parasite's ecological parameters and in its transmission to the definitive host. One-hundred-fifty specimens of P. argenteus were collected in July, 2003 (dry season) and...
Ecological parameters of the endohelminths in relation to size and sex of Proch...
Monteiro,Cassandra M.; Santos,Michelle D.; Zuchi,Nágila A.; Brasil-Sato,Marilia C.This research aimed to investigate the ecological indexes of the helminths of the digestive system and coelom of Prochilodus argenteus Spix & Agassiz, 1829. A total of 150 specimens (53 males and 97 females) taken from the upper reaches of the São Francisco River in the municipality of Três Marias (18º12'32"S, 45º15'41"W), State of Minas Gerais, Brazil, were examined. The specimens were collected in July, 2...

Monteiro,Cassandra M.; Amato,José F. R.; Amato,Suzana B.A new species of the genus Andracantha Schmidt, 1975, parasite of Neotropical cormorants, Phalacrocorax brasilianus (Gmelin, 1789), is described and compared to the other six species currently placed in the genus. The new species differs from the previously known species of Andracantha by having two inflations in the anterior region of the trunk and by having the testes in tandem in the central region of the bo...
Primeiro registro de Syncuaria squamata (Linstow) (Nematoda, Acuariidae) em big...
Monteiro,Cassandra M.; Amato,José F. R.; Amato,Suzana B.Os nematóides do gênero Syncuaria Gilbert, 1927 são parasitos de aves das ordens Pelecaniformes, Ciconiiformes e Podicipediformes. Onze espécies são consideradas válidas neste gênero, no entanto, somente duas, Syncuaria buckleyi (Ali, 1957) Wong, Anderson & Bartlett, 1986 e Syncuaria squamata (Linstow, 1883) Wong, Anderson & Bartlett, 1986 parasitam aves do gênero Phalacrocorax Brisson, 1760. Entre 1999...
Contracaecum rudolphii Hartwich (Nematoda, Anisakidae) from the Neotropical Cor...
Amato,José F. R.; Monteiro,Cassandra M.; Amato,Suzana B.The present report is part of a larger study on the helminth fauna of Neotropical Cormorants, Phalacrocorax brasilianus (Gmelin, 1789) in Brazil, particularly, in the southernmost State of Rio Grande do Sul. The nematodes which were found loose in the proventriculus/ventriculus or in groups of adults of different ages and of L3 and L4 larval stages, forming eosinophylic granulomas had a prevalence of 100% in 47...
