This note describes the first occurrence of Hapalotrema postorchis Rao, 1976 in the heart of Hawksbill sea turtle Eretmochelys imbricata Linnaeus, 1758, from Espírito Santo State, Brazil. This parasite has previously been reported only in Chelonia mydas from India, Australia, the United States, Costa Rica, and Taiwan. The note constitutes the first documented occurrence of this parasite in sea turtles from the western South Atlantic Ocean. © The Helminthological Society of Washington.

This paper describes the first occurrence of Rhytidodoides similis Price, 1939, parasitizing a juvenile green turtle (Chelonia mydas Linnaeus, 1758) found on the coast of Brazil. This parasite is known only from C. mydas, with previous reports of occurrences in the liver and gall bladder of green sea turtles found in the United States, Panama, and Costa Rica. In this case, no gross or microscopic lesions were found on the liver associated with R. similis. However, microscopic analysis of the liver revealed granulomas of trematode eggs consistent with spirorchiids. © 2015 The Helminthological Society of Washington.

The parasitic fauna of cetaceans is an important tool for ecological studies, including analyses on the causes of death. Halocercus brasiliensis is a nematode frequently found in the bronchi and bronchioles of some cetaceans, and it is commonly associated with focal inflammation of the respiratory tract leading to bacterial pneumonia and septicemia and, sometimes, to death. The objective of this study was to report infections by H. brasiliensis in the respiratory tract of Delphinidae stranded on the northern seaside of Bahia, Sergipe, and south of Alagoas, all states in the northeast region of Brazil. A total of 30 individuals, 1 Feresa attenuate (pygmy killer whale), 9 Stenella clymene (Clymene dolphin), and 20 Sotalia guianensis (Guiana dolphin) were studied. In 16 of them, the presence of H. brasiliensis was observed with a mean intensity of 3.5 ± 0.6 (range 1-9) in the hosts. Macroscopically, parasitic calcified nodules, lung congestion, edema, and emphysema were observed. Histopathological examination showed interstitial and granulomatous pneumonia with multifocal infiltrates, discrete to moderate edema, congestion, diffuse hemorrhage, and foci of calcification. We conclude that parasitic pneumonia in the sampled individuals may have directly contributed to stranding and death of the animals. © American Society of Parasitologists 2015.

Here we present the occurrence of Pyelosomum cochlear Looss 1899 in the urinary bladder of an olive ridley sea turtle Lepidochelys olivacea (Eschscholtz, 1829) from Brazil. This parasite species has previously been reported only from Chelonia mydas from Egypt, the United States (including Puerto Rico), Panama, and Costa Rica. This paper reports the first occurrence of P. cochlear parasitizing L. olivacea and the first occurrence of this parasite in the western South Atlantic. © 2015 The Helminthological Society of Washington.

We report the occurrence of Neospirorchis schistosomatoides Price 1934 in a juvenile green turtle (Chelonia mydas L.1758) from the Brazilian coast. This species has been reported only in green turtles from the USA, Bermuda and Australia. Only two entire specimens and parts of six worms were found in the host's heart. The collection, identification and morphometric data of intact specimens of N. schistosomatoides are rare and restricted to the original description. This paper presents the first report of N. schistosomatoides in green turtles from the western South Atlantic Ocean. © 2016 Institute of Parasitology, SAS, Košice 2016.

Journal of Parasitology | Year: 2015

The present study offers a parasitological analysis of juvenile individuals of the green turtle (Chelonia mydas) found on the Brazilian coast between 2004 and 2011. Helminths were found in 90 out of 136 individuals (66.2%, CI = 57.7-74.0). In total, 29,411 helminths were collected, belonging to the families Brachycoeliidae, Cladorchiidae, Microscaphidiidae, Pronocephalidae, Rhytidodidae, and Spirorchiidae. Mean species richness was 4.74 (CI = 4.03-5.46), the mean intensity was 327 (CI = 223-489), and the mean abundance was 216 (CI = 146-339). This study also reports new geographical records for: Angiodictyum longum, Angiodictyum parallelum, Rameshwarotrema uterocrescens, Pyelosomum cochlear, Schizamphistomum scleroporum, Cymatocarpus solearis, and Neospirorchis sp. This is the first analysis of helminth composition in juveniles of green turtles. © American Society of Parasitologists 2015.

The helminth fauna of 31 juvenile specimens of Eretmochelys imbricata from the Brazilian coast was examined. Seventeen individuals were infected with helminths (54.8%). The helminths found were: Diaschistorchis pandus, Cricocephalus albus, Metacetabulum invaginatum, Pronocephalus obliquus (Pronocephalidae), Cymatocarpus solearis (Brachycoeliidae), Styphlotrema solitaria (Styphlotrematidae), Carettacola stunkardi, Amphiorchis caborojoensis (Spirorchiidae), Orchidasma amphiorchis (Telorchiidae), and Anisakis nematode larvae. This report is the first analysis of parasite communities in this host.

The growth of human population and deficient pollution control measures pose significant challenge to the environment. Despite conservation efforts, all sea turtle species are at some risk of extinction. The present study investigated the effect of marine debris on the gastrointestinal tract of green turtles in southeastern Brazil. Of the 777 animals evaluated, 290 showed marine debris in one segment of the gastrointestinal tract. The presence of these materials in the gastrointestinal tract may be harmful, independent of the segment involved, and increases the risk of impaction. Marine debris has become a significant hazard to Chelonia mydas in the region surveyed, causing perforation, rupture, or fecal impaction that, when not treated, is potentially fatal, exposing the intestine to bacterial infection.
