brazilian spotted fever in cart horses in a non-endemic area in southern brazil.brazilian spotted fever (bsf) is an often fatal zoonosis caused by the obligate intracellular bacterium rickettsia rickettsii. the disease is generally transmitted to humans by amblyomma spp. ticks. serological evidence of past infection by r. rickettsii has been reported in horses, but the pathogenicity of r. rickettsii in horses remains unknown. cart horses are still widely used in urban and urban fringe areas in brazil, and these animals may constitute suitable sentinels for bsf human in thes ...201020624353
serological survey of rickettsia sp. in horses and dogs in a non-endemic area in brazil.brazilian spotted fever (bsf) is a lethal rickettsiosis in humans caused by the bacteria rickettsia rickettsii, and is endemic in some areas of brazil. horses and dogs are part of the disease's life cycle and they may also serve as sentinel animals in epidemiological studies. the first human bsf case in the state of paraná was reported in 2005. the present study was conducted in the municipality of almirante tamandaré, where no previous case of bsf was reported. serum samples were collected from ...201021184695
serosurvey of antibodies against spotted fever group rickettsia spp. in horse farms in northern paraná, brazil.brazilian spotted fever (bsf) is an emerging disease most likely caused by rickettsia rickettsii. the objective of the present study was to estimate the seroprevalence of bsf rickettsia infections in equines from six horse farms located in londrina county, paraná, southern brazil. six owners of horse farms situated in cambé, santa fé, guaraci and londrina municipalities participated in the study. all farms were located in areas where bsf has not been reported. a total of 273 horses were sampled ...201021184706
investigation of neospora sp. and toxoplasma gondii antibodies in mares and in precolostral foals from parana state, southern brazil.antibodies to neospora sp. and toxoplasma gondii were measured in mares and precolostral foals from a farm in parana state, brazil. an indirect fluorescent antibody test (ifat) was used to determine specific antibodies. three sampling points, 2003, 2004 and at parturition were included in the study, but not all horses are represented at a parturition time point. in 2003, antibodies to neospora were detected in 17 mares (47%) at 1:50 dilution and in 5 mares (13.8%) at 1:100 dilution. in 2004, ant ...200616289863
trends of fumonisin contamination and animal intoxication through monitoring 1991 to 1997 corn crop in the state of paraná, brazil.eleven feed samples associated with six animal (horse and poultry) intoxication outbreaks (1991) in the state of paraná, brazil, were evaluated for fungal and fumonisin contamination. in order to estimate the trend of livestock intoxication, fumonisin contamination was monitored in corn produced both at the commercial level (1991, 1995 crop), and in an experimental field at a local agronomy institute (1997 crop). the total mould count in the feed samples ranged from 2.9 x 10(3) to 1.9 x 10(7) cf ...200415630554
