Abstract: The aim of this study was to determine the frequency of anti-Neospora caninum antibodies and risk factors associated with seropositivity in 240 dogs from rural areas of the Lavras, Belo Horizonte and Nanuque regions, state of Minas Gerais, Brazil. The indirect fluorescence antibody test (IFAT) with a cutoff of 50 was used to assess the frequency of seropositive dogs. The risk factor analysis was performed using the Chi-square test (χ 2 ) and multiple logistic regression. The frequency of seropositivity for N. … Show more

“…In 28 (44.44%) of 63 farms were observed at least one seropositive dog, but there was no association between the presence of seropositive dairy cows and the presence of dogs or the presence of dogs positive for N. caninum on farms. Similarly, Guimarães et al (2004) and Bruhn et al (2012) reported frequencies of seropositive, respectively, among dogs in rural areas of Paraná (21.6%), and Minas Gerais (29.9%). Aguiar et al (2006) detected (also with a cutoff value of 1:50), among 172 dogs from rural area of Monte Negro, Rondônia lower percentage (12.6%) and, as reported in our study, did not also observed the presence of farm dogs as a risk factor for seropositivity among cattle.…”

“…This study observed that dogs that had contact with cattle were 15.25 times more likely to present with anti-N. caninum antibodies. Bruhn et al (2012) demonstrated that the conviviality of dogs with cattle was associated with the positivity of the protozoan (P = 0.053; odds ratio = 4.3). The result of this work can be attributed to acess to external parts of the property, increasing the chances of contact with tissues infected with the protozoan or even with intermediary hosts of the parasite, such as birds and wild animals.…”
