RESUMO
Antibodies to Neospora caninum were analyzed by an indirect fluorescent antibody test (IFAT), in stray and domiciled dogs from urban, periurban and rural areas from Curitiba, Paraná State, Brazil. Of the total of 556 dogs, 18.17 percent (101) were positive for N. caninum (titer 50). Frequency of antibody was 12.71 in urban, 15.73 in periurban, and 25.38 percent in rural dogs. Rural dogs had a significantly higher frequency of antibodies than urban dogs (P< 0.05). There were no significant differences between the frequencies of antibodies in urban and periurban dogs (P>0.05), and between dogs from periurban and rural areas (P>0.05). Antibodies to N. caninum were detected in 34 of 233 domiciled dogs (14.59 percent) and in 17 of 126 stray dogs (13.49 percent). No statistical differences were observed considering life-style and geographic location of origin (P>0.05). Neospora caninum is widespread among dogs from urban, periurban and rural areas of the municipal district of Curitiba, Paraná, Brazil.
Anticorpos anti-Neospora caninum foram detectados pela reação de imunofluorescência indireta (RIFI), em cães errantes e domiciliados das áreas urbana, periurbana e rurais de Curitiba, estado do Paraná, Brasil. Do total de 556 cães, 18,17 por cento (101) foram soropositivos para N. caninum (título de 1:50). A frequência de anticorpos foi de 12,71 por cento nos cães urbanos, de 15,73 por cento nos periurbanos e de 25,38 por cento nos cães rurais. Nos cães rurais a frequência de anticorpos foi maior do que nos cães urbanos (P<0.05). Não houve diferença significativa entre as frequências de anticorpos dos cães urbanos e periurbanos (P>0,05), e dos periurbanos e rurais (P>0,05). Os anticorpos anti N. caninum foram detectados em 34 de 233 cães domiciliados (14,59 por cento) e em 17 de 126 cães errantes (13,49 por cento). Não houve diferença estatística significativa entre o tipo de criação e a origem (P>0,05). Neospora caninum está presente nos cães urbanos e periurbanos de Curitiba e nas áreas rurais do Estado do Paraná.

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.
