Recientemente, se han presentado datos sobre lista de verificación de los platelmintos parásitos de los seres humanos depositados en Helminthological Colección del Instituto Oswaldo Cruz (CHIOC), Rio de Janeiro, Brasil. El presente estudio se relaciona con la lista de verificación de los nematodos parásitos de humanos. Existen varios tipos de helmintos depositados en la CHIOC, incluidos los parásitos de importancia médica y veterinaria. Las muestras están depositadas como material líquido o montaje final. Para obtener el conocimiento de los nematodos que parasitan al hombre depositados en CHIOC, se realizo un estudio de sus muestras en su base de datos informatizada y sus fichas de catálogo. Se analizaron un total de 169 fichas de catálogo con 176 muestras depositadas con 15 especies. Una lista de estos helmintos se generó a partir del número de depósito de las muestras ana...

Contiene especies representativas de diversos biomas, testimonios de la biodiversidad brasileña y de otros países. Existen varios tipos de helmintos depositados en la misma, incluidos los parásitos de importancia médica y veterinaria. Las muestras están depositadas como material líquido o montaje final. Para obtener el conocimiento de los platelmintos que parasitan al hombre depositados en CHIOC, se realizó un estudio de sus muestras en su base de datos informatizada y sus fichas de catálogo. Se analizaron un total de 113 fichas de catálogo con 236 muestras depositadas en la CHIOC. Una lista de estos helmintos se generó a partir del número de depósito de las muest...

The present findings update of previously published results on the nematodes parasitizing Brazilian mammals, with the inclusion of other genera, species and hosts. Measurements and illustrations are only related to the nematodes representing new taxa, and to those that were either redescribed or reported in Brazil occurring in mammals since 1997: Ancylostoma pluridentatum (Alessandrini, 1905), Angiostrongylus lenzii Souza, Simões, Thiengo, Lima, Mota, Rodrigues-Silva, Lanfredi, Maldonado Jr, 2009, Anisakis physeteris Baylis, 1923, A. simplex (Rudolphi, 1808) Dujardin, 1845, A. typica (Diesing, 1860), Anisakis sp., Ascaris elongata (Rudolphi, 1819), Avellaria intermedia Durette- Desset, Gonçalves & Pinto, 2006, Cheiropteronema globocephala Sandground, 1929, Contracaecum sp., Dentostomella translucida Schulz & Krepkorgorskaya, 1932, Freitastrongylus angelae Gonçalves, Pinto &...

During studies of fish helminths, deposited in the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC), some samples of nematodes were studied and identified as Rhabdochona uruyeni Diaz-Ungria, 1968. The present status of the species occurring in South America is discussed and updated. To facilitate further accesses, a worldwide bibliographical survey related to systematic, taxonomic, morphological, biological, cladistical and ecological approaches to the genus, covering a period of 165 years is presented. To date, Rhabdochona (Rhabdochona) acuminata is referred in Argentina, Brazil, and Ecuador, together with Rhabdochona (Filochona) fabianae in Argentina and Rhabdochona (Rhabdochona) uruyeni in Venezuela and now in Brazil, for the first time and in a new host. Also, Rhabdochona spp. are cited in Argentina, Brazil and Peru. Rhabdochona colossomi Diaz-Ungria, 1968 is conside...

Between October 2006 and March 2008, 60 specimens of Paralichthys isosceles were captured in the littoral of the State of Rio de Janeiro, Brazil, to be investigated for anisakid nematodes, due to their zoonotic relevance. Five species of larval anisakid were present, in a total amount of 1,900 worms. One thousand eighty hundred and twenty larvae of Hysterothylacium sp., 71 of Raphidascaris sp., four of Terranova sp., three of Anisakis simplex and two of Contracaecum sp. were recovered. Parasites were found infecting the abdominal cavity, mesentery, intestine, liver, stomach mucosa, stomach, ovaries, abdominal musculature, and serosas of the heart, spleen, stomach, kidneys and ovaries. Hysterothylacium sp. appeared with a prevalence (P) of 100%, mean intensity (MI) of 30.3, range of infection (RI) of 1 to 596 and mean abundance (MA) of 30.3; Raphidascaris sp. with P = 36.7%, MI = 3.2, RI ...

De julio a diciembre de 2013, fueron comprados 30 ejemplares de Priacanthus arenatus (Cuvier, 1829) comercializados en los municipios de Niterói y Rio de Janeiro, Estado de Rio de Janeiro, Brasil. Alos peces se les practicó la autopsia y se filetearon para investigar la presencia de larvas de cestodos. Tres peces fueron parasitados con trypanorhyncha y fueron identificados como Callitetrarhynchus speciosus (Linton, 1897) Carvajal & Rego, 1985 basado en caracteres morfológicos y morfométricos. Los índices parasitarios de prevalencia, abundancia media, la intensidad media y los sitios de infección son presentados. Los plerocercos se encontraron en el mesenterio, y serosas del ovario y del intestino. Estos parásitos se estudiaron por su importancia para la inspección sanitaria de los peces, teniendo en cuenta el daño que el aspecto repulsivo de los peces infectados impulsa a los co...

In January 2002, were caught 11 Makaira nigricansLacepède, 1802 (Istiophoridae) and two Acanthocybium solandri(Cuvier, 1832) (Scombridae) off Cabo Frio municipality, Rio de Janeiro State, Brazil. We collected digenetic trematodes from the stomach of some of these fishes. We studied these trematodes with optical and scanning electron microscopy and identified them as Hirudinella ventricosa(Pallas, 1774) Baird, 1835. This is the first report of this species in A. solandriin the Brazilian coast, and in M. nigricansin South America.

From October 2006 to March 2008, sixty specimens of Paralichthys isosceles, were captured in the littoral of the State of Rio de Janeiro Brazil. The present study deals with the taxonomic identification of the cestodes parasitizing this fish species, as well with the analysis of parasitological indexes, sites of infection, taking into account the hygienic-sanitary importance of the host in Brazilian and foreign markets. Fifty-six (93.3%) out of the collected fishes were infected with at least one specimen of metacestodes. Diphyllobothriidea were represented by plerocercoids of two species: Diphyllobothrium sp. 1 (similar to D. latum) in stomach, stomach mucosa and mesentery and Diphyllobothrium sp. 2 (similar to D. dendriticum) in intestine, liver, ovary and abdominal cavity. Trypanorhyncha, were represented by Grillotia carvajalregorum, in stomach, intestine, liver, mesentery, abdominal...
