| prevalence of two species of litomosoides (nematoda: filarioidea) parasites of akodon cursor (rodentia: muridae) from southeastern brazil. | two species of filariids, litomosoides silvai and litomosoides chagasfilhoi, were collected from the thoracic and abdominal cavities, respectively, of akodon cursor, from catimbau grande, rio bonito, rio de janeiro, brazil. fifty-eight rodents were necropsied and 15 (25.9%) were parasitized. four of the 15 infected rodents (26.7%) presented concurrent infections, but each species had separate and specific sites of infection. this is the first report of a rodent species parasitized with naturally ... | 1997 | 9440357 |
| the first description of eggs in the male reproductive system of physaloptera bispiculata (nematoda: spiruroidaea). | physaloptera bispiculata (nematoda: spiruroidaea) is a parasite of nectomys squamipes (rodentia: cricetidae), a water rat that only occurs in brazil. naturally infected rodents were captured in the municipality of rio bonito, rio de janeiro, brazil. adult p. bispiculata worms were collected, prepared and analysed by light and scanning electron microscopy. under scanning electron microscopy, several eggs were seen glued by cement to the cloacal aperture. light microscopy revealed that some male w ... | 2010 | 20653989 |
| some digenea parasites of tunny from the coast of rio de janeiro state, brazil. | rhipidocotyle pentagonum (ozaki, 1924) is reported for the first time in south america parasitizing auxis thazard and in a new host katsuwonus pelamis. tergestia laticollis (rudolphi, 1819) is reported for the first time in south america and in thunnus albacares, representing a new host record. copiatestes filiferus (leuckart, in sars, 1885) is recorded for the first time in brazil and in thunnus albacares, another new host record. tetrochetus coryphaenae (yamaguti, 1934) is presented for the fi ... | 2002 | 12530181 |
| thraulodes bonito sp. nov. (ephemeroptera: leptophlebiidae) from rio de janeiro state, southeastern brazil. | a new species of thraulodes ulmer, 1920 is described from rio de janeiro. the species resembles the recently published thraulodespelicanus mariano and froehlich, 2011 (in mariano et al. 2011) due to the length and width of the penes. however, thraulodes bonito sp. nov. differs from this and all other species of the genus by the wide penes, the triangular shape of the styliger plate with median projection short and apex rounded, the abdominal color pattern and the presence of 1-3 weakly marked cr ... | 2013 | 26312330 |
| mapping of the environmental contamination of toxoplasma gondii by georeferencing isolates from chickens in an endemic area in southeast rio de janeiro state, brazil. | the environmental contamination of toxoplasma gondii in an endemic area in brazil was mapped by georeferencing isolates from chickens in farms in the southeast of the state of rio de janeiro. tissue samples obtained from 153 adult chickens were analyzed by the mouse bioassay for t. gondii infection. these animals were reared free-range on 51 farms in the municipalities of rio bonito and maricá. the arcgis kernel density estimator based on the frequency of t. gondii-positive chickens was used to ... | 2015 | 26054514 |
| new morphological data of litomosoides chagasfilhoi (nematoda: filarioidea) parasitizing nectomys squamipes in rio de janeiro, brazil. | litomosoides chagasfilhoi, originally described by moraes neto, lanfredi & de souza (1997) parasitizing the abdominal cavity of the wild rodent, akodon cursor (winge, 1887), was found in the abdominal cavity of nectomys squamipes (brants, 1827), from the municipality of rio bonito, rio de janeiro state, brazil. this study led to addition of new morphological data and a new geographical distribution for this filarioid in brazil. several characters were detailed and emended to previous records of ... | 2016 | 27925058 |
