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 c...
متن کاملMorphological 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 seq...
متن کاملMitochondrial DNA sequence-based phylogenetic relationship of Trichiurus lepturus (Perciformes: Trichiuridae) from the Persian Gulf
In this study, mitochondrial DNA analysis using 16S ribosomal DNA (rDNA) was performed to investigate the phylogeny relationship of Trichiurus lepturus in the Persian Gulf compared to the other investigated area. The amplification of 16S rDNA resulted in a product of 600 bp in all samples. The results showed that the isolated strain belongs to T. lepturus showing 42 divergence sites among the s...
متن کاملSeasonal variation of hepatitis A virus infection in the city of Rio de Janeiro, Brazil.
Hepatitis A virus (HAV) infection constitutes a major public health problem in Brazil. The transmission of HAV is primarily by fecal-oral route so the water is an important vehicle of HAV dissemination. There is a great incidence of acute cases of hepatitis A in some areas of Brazil however the seasonal variation of these cases was not documented. The aim of this study was to determine the seas...
متن کاملSeasonal variation of food intake of adults from Niterói, Rio de Janeiro, Brazil.
The measurement of usual food intake (FI) is necessary to accurately establish the relationship between diet and disease. In most studies data are collected at one particular time of the year, which may influence the interpretation of the results. The purpose of this study was to investigate the effect of seasonality on FI in a sample of adults from Niterói, RJ, Brazil. A total of 102 healthy s...
