Abstract According to the World Health Organization, snakebites are considered neglected diseases. Bothrops, the genus most frequently implicated in envenomations in Brazil, includes the species B. marajoensis Hoge, 1966, part of the complex B. atrox, which is found in the savannas of Marajó Island, Pará state, Brazil, a region that presents scarce epidemiological data. This work reports the first case of hemorrhagic stroke in a child, attributed to delayed medical care after snakebite envenoming by Bothrops marajoensis in Anajás city, Marajó Island, Pará, Brazil, which led to permanent hemiplegia as a sequela. |

A short inventory of the mammalian fauna occurring in an area of the Marajó Island was performed during the rainy season. In addition to captures by using Sherman and Tomahawk traps, and mist-nets, indirect evidence was considered, e.g. finding of body fragments of specimens, vocalization, and testimonies from local people. A total of 57 species (22 families) was recorded. None of them is presently considered as critically endangered according to the IUCN criteria. First confirmed record for the fruit-eating bat Platyrrhinus brachycephalus (Rouk & Carter, 1972) in the Marajó archipelago. Additional surveys conducted in both wet and dry seasons are required for improving the profile of richness and diversity of mammal species in that region. |

Studies suggest that the Marajó Island has experienced neotectonic activity during its latest evolution. However, there are no data demonstrating the presence of tectonic structures in its shallow subsurface. This work integrates vertical electric sounding, morphostructural lineaments, and geological data aiming to show fault control on the Late Pleistocene-Holocene sedimentation of this area. Resistivity values were related to mud (< 90 Ωm), clayey sand (90 and 200 Ωm), sand (200 and 500 Ωm), as well as Fe-bearing sand and laterite (> 500 Ωm). The latest values were related to the unconformity with lateritic paleosol at the top of the Barreiras Formation. Despite the values ≤ 500 Ωm of both the Barreiras Formation and the Late Pleistocene-Holocene... |

Marajó Island shows an abundance of paleochannels easily mapped in its eastern portion, where vegetation consists mostly of savannas. SRTM data make possible to recognize paleochannels also in western Marajó, even considering the dense forest cover. A well preserved paleodrainage network from the adjacency of the town of Breves (southwestern Marajó Island) was investigated in this work combining remote sensing and sedimentological studies. The palimpsest drainage system consists of a large meander connected to narrower tributaries. Sedimentological studies revealed mostly sharp-based, fining upward sands for the channelized features, and interbedded muds and sands for floodplain areas. The sedimentary structures and facies successions are in perfect... |

A total of 40 specimens of the teleost fish Gobioides grahamae Palmer & Wheeler, 1955 were obtained from the municipality of Salvaterra on Marajó Island in the Brazilian state of Pará. Their livers were removed and processed for light microscopy. Overall, 90% of the specimens presented some degree of steatosis of the liver, which was invariably associated with the presence of Microsporidium sp. The present study confirms the occurrence of steatosis in G. grahamae associated with parasitic infections by Microsporidium. The findings indicate that the condition of otherwise healthy fishes in their natural environment may be affected negatively by parasites. |

ABSTRACT: Two outbreaks of trypanosomiasis by Trypanosoma evansi in horses in the municipality of Chaves, Marajó Island, Pará State, Brazil are reported. The first outbreak occurred in April 2011 in a farm with 147 horses; of these, 47 (31.97%) got sick, and 40 (27.21%) died. The second outbreak occurred in May 2012 and involved nine properties. Of a total of 679 horses, 209 (30.07%) got sick, and 183 (26.97%) died. The main clinical signs observed in these horses were weight loss, abdominal edema, toe dragging, and pelvic muscle atrophy. Necropsy was performed in two horses, one from each outbreak. Macroscopic alterations were not seen in the horse from the first outbreak; however, the horse from the second outbreak exhibited emaciation, pallor and... |
