| spotted fever group rickettsia in small rodents from areas of low endemicity for brazilian spotted fever in the eastern region of minas gerais state, brazil. | we investigated the humoral immune response against different species of rickettsia in serum samples from small rodents collected in two areas of a silent focus for brazilian spotted fever in the eastern region of minas gerais state, brazil. sera samples were analyzed by indirect immunofluorescence assay using antigens from rickettsia species of the spotted fever, ancestral, and transition groups. titers ≥ 1:64 were considered positive. in santa cruz do escalvado, 94% (30 of 32) of the samples c ... | 2013 | 23509125 |
| detection of leishmania spp in silvatic mammals and isolation of leishmania (viannia) braziliensis from rattus rattus in an endemic area for leishmaniasis in minas gerais state, brazil. | knowledge of potential reservoirs of leishmania spp. in an anthropic environment is important so that surveillance and control measures can be implemented. the aim of this study was to investigate the infection by leishmania in small mammals in an area located in minas gerais, brazil, that undergoes changes in its natural environment and presents autochthonous human cases of cutaneous leishmaniasis (cl) and visceral leishmaniasis (vl). for the capture of the animals, sherman and tomahawk traps w ... | 2017 | 29176902 |
| leishmania (viannia) braziliensis infection in wild small mammals in ecotourism area of brazil. | leishmaniases are parasitic diseases transmitted to mammalian hosts by sand fly vectors (diptera: psychodidae). despite the increasing occurrence of visceral and cutaneous leishmaniasis cases in urban centers, their transmission still occur primarily in wild environments and may be associated with professional activities and recreation, such as ecotourism. the reserva particular do patrimônio natural santuário do caraça (rppnsc) is one of the largest ecotourism attractions in the state of minas ... | 2017 | 29284049 |
| composition and abundance of small mammal communities in forest fragments and vegetation corridors in southern minas gerais, brazil. | habitat fragmentation leads to isolation and reduce habitat areas, in addition to a series of negative effects on natural populations, affecting richness, abundance and distribution of animal species. in such a context, habitat corridors serve as an alternative for connectivity in fragmented landscapes, minimizing the effects of structural isolation of different habitat areas. this study evaluated the richness, composition and abundance of small mammal communities in forest fragments and in the ... | 2012 | 23025102 |
| a small mammal community in a forest fragment, vegetation corridor and coffee matrix system in the brazilian atlantic forest. | the objective of our work was to verify the value of the vegetation corridor in the conservation of small mammals in fragmented tropical landscapes, using a model system in the southeastern minas gerais. we evaluated and compared the composition and structure of small mammals in a vegetation corridor, forest fragments and a coffee matrix. a total of 15 species were recorded, and the highest species richness was observed in the vegetation corridor (13 species), followed by the forest fragments (1 ... | 2011 | 21912591 |
| pcr-based diagnosis for detection of leishmania in skin and blood of rodents from an endemic area of cutaneous and visceral leishmaniasis in brazil. | the technique of polymerase chain reaction (pcr) associated to hybridization was used to screen 123 samples collected from wild and synanthropic rodents captured in a cutaneous and visceral leishmaniasis endemic area in the state of minas gerais, brazil. the detection of leishmania spp in naturally infected rodents is of fundamental importance for incriminating them as possible reservoir hosts of the diseases in minas gerais. a total of 62 specimens belonging to wild (thrichomys apereoides, oryz ... | 2005 | 15845276 |
