The protozoan parasite Neospora caninum is a major cause of abortion in cattle worldwide. The aim of the present study was to determine and to compare the presence of anti-Neospora caninum antibodies in cattle, as well as in farm dogs, and the relationship among them. The research was conducted in different mesoregions of Paraná state, Southern Brazil. Sera from 1.263 cattle, from 77 farms were tested for antibodies to N. caninum by ELISA. Sera from 129 dogs, from 35 farms were tested for antibodies to N. caninum by indirect fluorescent antibody test (IFAT). Antibodies to N. caninum were found in 423 of 1.263 bovines (33%), and in 32 of 129 dogs (25%). The seroprevalence of antibodies for N.caninum in cattle was not significantly higher in farms with seropositive dogs when compared to farms with no seropositive dogs. Thus, these results suggest that seropositive dogs to N. caninum did not contribute for the seroprevalence in cattle. Neospora caninum is widespread among cattle and dogs from rural areas of all mesoregions of Paraná, Brazil.
原生动物寄生虫犬新孢子虫是全球范围内牛流产的主要原因。本研究的目的是确定并比较牛以及农场犬中抗犬新孢子虫抗体的存在情况，以及它们之间的关系。该研究在巴西南部巴拉那州的不同中区域进行。通过酶联免疫吸附测定法（ELISA）对来自77个农场的1263头牛的血清进行犬新孢子虫抗体检测。通过间接荧光抗体试验（IFAT）对来自35个农场的129只犬的血清进行犬新孢子虫抗体检测。在1263头奶牛中有423头（33%）检测到犬新孢子虫抗体，在129只犬中有32只（25%）检测到该抗体。与没有血清阳性犬的农场相比，有血清阳性犬的农场中牛的犬新孢子虫抗体血清阳性率并无显著更高。因此，这些结果表明，血清阳性犬对牛的血清阳性率并无影响。犬新孢子虫在巴西巴拉那州所有中区域农村地区的牛和犬中广泛存在。
