VIEIRA, Y. R.; PORTILHO, M. M.; OLIVEIRA, F. F.; GUTERRES, A.; SANTOS, D. R. L dos; VILLAR, l. M.; MIRAZO, S.; ARBIZA, J.; DIMACHE, L. A. G.The origin of the hepatitis B virus is a subject of wide deliberation among researchers. As a result, increasing academic interest has focused on the spread of the virus in different animal species. However, the sources of viral infection for many of these animals are unknown since transmission may occur from animal to animal, human to human, animal to human, and human to animal. The aim of this study was to ev...
Risk of exposure of farms and subsistence nurseries to contact with wild boar i...
BRAZ, P. H.; OLIVEIRA, M. R.; SILVA, V. S.; TOMAS, W. M.; JULIANO, R. S.; MOREIRA, T. A.; ZIMMERMANN, N. P.; PELLEGRIN, A. O.Abstract: With the advancement of wild boar distribution in the rural environment, its impacts are not limited to health in the pig sector, but the requirements for monitoring and control of the species are requirements laid down by the OIE for the recognition of classical swine fever free zone status. The construction of ecological models of favorability or suitability for the occurrence of pest species are ne...
Wildlife species, Ixodid fauna and new host records for ticks in an Amazon fore...
ZIMMERMANN, N. P.; AGUIRRE, A. de A. R.; RODRIGUES, V. da S.; GARCIA, M. V.; MEDEIROS, J. F.; BLECHA, I. M. Z.; DUARTE, P. O.; CRUZ, B. C.; CUNHA, R. C.The objective of this work was to evaluate the diversity of ticks associated with free-living animals and to investigate new host records for ticks. Ticks were collected from animals rescued during the flood of the Jamari River in the municipality of Ariquemes, state of Rondônia, North Region of Brazil. A total of 39 animals were captured, out of which 10 were amphibians, 19 were reptiles and 10 were mammals. A...
Ticks on Didelphis albiventris from a Cerrado area in the Midwestern Brazil.
DE SÁ, E. F. G. G.; RODRIGUES, V. DA S.; GARCIA, M. V.; ZIMMERMANN, N. P.; RAMOS, V. Do N.; BLECHA, I. M. Z.; DUARTE, P. De O.; MARTINS, T. F.This experiment studied tick fauna associated to Didelphis albiventris Lund 1840 from a Cerrado area (Mato Grosso do Sul State, non-adjoining to Pantanal) inserted in a pasture and agricultural activities matrix, with few natural preserved forest patches. Authors also summarized data on ticks parasitizing Didelphis spp. in Brazil, and discussed infestation patterns in different biomes and locations. Study took ...

RODRIGUES, V. da S.; GARCIA, M. V.; CRUZ, B. C.; MACIEL, W. G.; ZIMMERMANN, N. P.; KOLLER, W. W.; BARROS, J. C.; ANDREOTTI, R.The objective of this study was to evaluate the life cycle and parasitic competence of Dermacentor nitens(Neumann, 1897) on different animal species. Experimental infestations were induced in five specimenseach of seven species of possible hosts: rabbits, horses, sheep, cows, guinea pigs, birds and dogs. Rabbitswere infested in the ear using artificial feeding chambers, and the horses, sheep, cows and dogs were...
