| genetic characterization of hantaviruses associated with sigmodontine rodents in an endemic area for hantavirus pulmonary syndrome in southern brazil. | an ecological assessment of reservoir species was conducted in a rural area (jaborá) in the mid-west of the state of santa catarina in southern brazil, where hantavirus pulmonary syndrome is endemic, to evaluate the prevalence of hantavirus infection in wild rodents. blood and tissue samples were collected from 507 rodents during seven field trips from march 2004 to april 2006. some of the animals were karyotyped to confirm morphological identification. phylogenetic reconstructions of rodent spe ... | 2010 | 21138380 |
| besnoitia sp. (protozoa:toxoplasmatinae) from akodon montensis (rodentia:cricetidae) in santa catarina state, brazil. | tissue cysts of besnoitia sp. were found in muscles and several organs from a naturally infected akodon montensis captured in the rural area of the municipality of timbó, santa catarina state, in southern brazil. indirect fluorescence and enzyme-linked immunosorbent assays carried out with sera from mice chronically infected with toxoplasma gondii and besnoitia sp. showed, as expected, a stronger reaction against homologous than heterologous antigens. no cross-protection was observed in mice imm ... | 1997 | 9105318 |
| noteworthy records of ixodes schulzei (acari: ixodidae) on rodents from the state of parana, southern brazil. | ixodes schulzei aragão & fonseca is an endemic tick to brazil and has already been reported in the northern (state of rondonia), southeastern (states of minas gerais, rio de janeiro and sao paulo) and southern (state of santa catarina) regions, always found in association with the water rat nectomys squamipes (brandt). this communication records the first occurrence of this tick species in the state of parana, southern region of brazil, and it constitutes its first report on akodon montensis (th ... | 2013 | 24252964 |
| ecological study of hantavirus infection in wild rodents in an endemic area in brazil. | a 3-year ecological study of small mammals was carried out in an endemic area for hantavirus pulmonary syndrome in the state of santa catarina in southern brazil. a total of 994 rodents of 14 different species corresponding to the subfamilies of sigmodontinae, murinae, eumysopinae, and caviinae were captured during 2004-2006. oligoryzomys nigripes and akodon montensis were the most abundant species and showed a clear seasonal pattern with higher population sizes during the winter. rodent populat ... | 2014 | 24291677 |
| detection of the first incidence of akodon paranaensis naturally infected with the jabora virus strain (hantavirus) in brazil. | we characterised hantaviruses circulating in different akodon rodent species collected in midwestern santa catarina (sc), southern brazil, where the jabora hantavirus (jabv) strain was first identified in akodon montensis. genetic and phylogenetic analyses based on a partial s segment indicated that, in sc, akodon paranaensis and a. montensis carried the same type of hantavirus. additionally, we conducted the first genomic characterisation of the complete s segment from the brazilian jabv strain ... | 2012 | 22510841 |
| differences in richness and composition of gastrointestinal parasites of small rodents (cricetidae, rodentia) in a continental and insular area of the atlantic forest in santa catarina state, brazil. | the first and only study on gastrointestinal parasites of wild rodents in the island of santa catarina was done in 1987. the aim of this study was to identify intestinal parasites from wild rodents in santo amaro da imperatriz and santa catariana island, and to compare the richness and composition of the gastrointestinal parasite community of both areas. rodents were captured with live traps, and feces were screened using the sedimentation method and optical microscopy. the following species of ... | 2012 | 22990827 |
