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.

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.

This note reports the occurrence of Hapalotrema postorchis Rao 1976 collected from an aortic aneurysm in a green turtle (Chelonia mydas Linnaeus 1758) found on the coast of Brazil. Besides the vascular lesion, granulomatous reactions with foreign - body giant cells were found surrounding the parasite eggs in the heart, intestines, liver, pancreas, spleen, brain and kidneys. This paper presents the first report of H. postorchis and accompanying lesions in a green sea turtle from the western South Atlantic Ocean. © 2015 Institute of Parasitology, SAS, Košice.

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.

This note reports the first occurrence of Monticellius indicum Mehra, 1939, in the heart of the Hawksbill turtle, Eretmochelys imbricata Linnaeus, 1766, in the state of Espírito Santo, Brazil. This parasite has only previously been reported, to our knowledge, in Chelonia mydas from India, Brazil, and Costa Rica. © 2015 The Helminthological Society of Washington.
