| morphological and molecular diagnosis of anisakid nematode larvae from cutlassfish (trichiurus lepturus) off the coast of rio de janeiro, brazil. | anisakid nematode larvae from trichiurus lepturus off coast of rio de janeiro were studied using light, laser confocal and scanning electron microscopy, in addition to a molecular approach. mitochondrial cytochrome c-oxidase subunit 2 (mtdna cox-2), partial 28s (lsu) and internal transcribed spacers (its-1, 5.8s, its-2) of ribosomal dna were amplified using the polymerase chain reaction and sequenced to evaluate the phylogenetic relationships between the nematode taxa. the morphological and gene ... | 2012 | 22792329 |
| [occurrence of neobenedenia melleni (monogenea: capsalidae) in trichiurus lepturus (perciformes: trichiuridae), naturally infested of coastal zone of rio de janeiro, brazil]. | neobenedenia melleni (maccallum, 1927) is a widely spread pathogen in teleost maricultures with a very low host specificity. between july of 2006 to june of 2007, 120 specimens of trichiurus lepturus linnaeus, 1758 were acquired of local fishermen in the guanabara bay (22 degrees 57' s and 42 degrees 41' w), state of rio de janeiro, brazil, to the study of the parasite fauna. the surface of the host body was scraped and the monogeneans obtained were identified as n. melleni, which showed prevale ... | 2009 | 20040197 |
| total mercury in carnivorous fish from brazilian southeast. | total mercury concentrations were determined by atomic absorption spectrometry in muscle tissue of two commercially important species of carnivorous fishes croaker (micropogonias furnieri) and cutlassfish (trichiurus lepturus) caught in itaipu estuary, rio de janeiro. in this study, whitemouth croaker presented more mercury than atlantic cutlassfish. bioaccumulation differences can be explained by the biological behavior of juveniles whitemouth croaker, that remain in the estuary up to maturity, ... | 2015 | 25666565 |
| seasonal variation in metazoan parasites of trichiurus lepturus (perciformes: trichiuridae) of rio de janeiro, brazil. | this work aimed to study the temporal variation of metazoan parasites of trichiurus lepturus from the coastal zone of rio de janeiro, brazil. between july 2006 and june 2007, there were four seasonal quarterly samples of 30 specimens of t. lepturus. in addition to a group composed of anisakid larvae, we collected a total of 14 species of metazoan parasites: five digenean; five monogenean, two cestode larvae, one acanthocephalan larvae; and one copepod. with the exception of lecithochirium micros ... | 2011 | 21881803 |
