Helminth parasitism in the Neotropical cormorant, Phalacrocorax brasilianus, in Southern Brazil: effect of host size, weight, sex, and maturity state
TLDR
The present work records the richest helminth fauna for any bird of the genus Phalacrocorax and is the first study to evaluate the influence of length, weight, sex, and maturity state on parasitism. Expand
Myxobolus franciscoi sp. nov. (Myxozoa: Myxosporea: Myxobolidae), a parasite of Prochilodus argenteus (Actinopterygii: Prochilodontidae) from the Upper São Francisco River, Brazil, with a revision of
TLDR
Thorough comparisons with the remaining species of Myxobolus Butschli, 1882 described from South American fish, as well as with almost all species of Herbarium described so far, are provided. Expand
Neotropical Monogenoidea. 55. Dactylogyrids parasitising the pintado-amarelo Pimelodus maculatus Lacépède (Actinopterygii: Pimelodidae) from the Rio São Francisco, Brazil
Eight species of Dactylogyridae were collected from the gills of the pintado-amarelo Pimelodus maculatus Lacépède in the Rio São Francisco in Brazil: Ameloblastella paranaensis (França, Isaac,Expand
Neotropical Monogenoidea. 56. New species of Anacanthorus (Dactylogyridae) from the gills of matrinchã, Brycon orthotaenia (Characiformes: Characidae), in the Rio São Francisco, Brazil.
TLDR
The gills of the matrinchã, Brycon orthotaenia Günther, from the Rio São Francisco in Brazil are described from the gills and Anacanthorus brevicirrus resembles A. franciscanus, A. kruidenieri and A. elegans but is differentiated from these species by its short straight male copulatory organ.

Metazoan parasites of Geophagus brasiliensis (Perciformes: Cichlidae) in Patos Lagoon, extreme south of Brazil.
TLDR
Pearl cichlids are registered as a new host for the trematodes Lobatostoma sp. Expand
Digenea of Hoplias intermedius and Hoplias malabaricus (Actinopterygii, Erythrinidae) from upper São Francisco River, Brazil.
TLDR
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
Ecological parameters of the endohelminths in relation to size and sex of Prochilodus argenteus (Actinopterygii: Prochilodontidae) from the Upper São Francisco River, Minas Gerais, Brazil
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 97Expand
New species and reports of dactylogyrids (Monogenoidea) from Salminus franciscanus (Actinopterygii: Bryconidae) from the upper São Francisco River, Brazil.
TLDR
Six species of dactylogyrid monogenoideans were collected at the upper São Francisco River, State of Minas Gerais, Brazil, from the gills of Salminus franciscanus, a new host record and a new locality record for Anacanthorus daulometrus, Annulotrematoides glossophallus, Jainus iocensis and Tereancistrum arcuatus.

Contracaecum rudolphii Hartwich (Nematoda, Hartwich (Nematoda,
TLDR
The morphology of the labia/interlabia, the distribu- tion pattern of the caudal papillae in males examined under scanning electron microscopy (SEM), and the tips of the spicules allowed determination of the species as Contracaecum rudolphii Hartwich, 1964 sensu lato (s. l.). Expand
