Occurrence of Amphiorchis indicus Mehrotra, 1973 (Digenea, Spirorchiidae) infecting green turtle Chelonia mydas Linnaeus, 1758 (Testudines, Cheloniidae) in Brazil.

First report of Monticellius indicum Mehra, 1939 (Digenea: Spirorchiidae) infecting Chelonia mydas Linnaeus, 1758 (Testudines: Chelonidae) from Brazil.

The family Spirorchiidae includes trematodes of freshwater and marine chelonian blood vessels. Up to now, Learedius learedi Price, 1934 has been the only species of this family described in Brazil (Werneck et al., 2006). The present study reports for the first time the occurrence of Monticellius indicum Mehra, 1939 in Brazilian waters. Specimens of M. indicum were collected from the heart of tw...

Flow cytometry as a tool in the evaluation of blood leukocyte function in Chelonia mydas (Linnaeus, 1758) (Testudines, Cheloniidae).

Chelonia mydas is a sea turtle that feeds and nests on the Brazilian coast and a disease called fibropapillomatosis is a threat to this species. Because of this, it is extremely necessary to determine a methodology that would enable the analysis of blood leukocyte function in these sea turtles. In order to achieve this aim, blood samples were collected from C. mydas with or without fibropapillo...

Mercury in the sea turtle Chelonia mydas (Linnaeus, 1958) from Ceará coast, NE Brazil.

Mercury concentrations in carapace fragments of the green turtle Chelonia mydas from the Ceará coast in NE Brazil are reported. Concentrations varied from <0.34 to 856.6 ng.g(-1) d.w., and were highest (average of 154.8 ng.g(-1) d.w.) in juveniles (n = 22), whereas lowest concentrations (average of 2.5 ng.g(-1) d.w.) were observed in adult/sub-adult animals (n = 3). There was a significant nega...
