| Toxoplasma gondii is a worldwide parasite recognized as one of the main zoonosis in human beings. The present study aimed to evaluate serology of T. gondii from dairy cows slaughtered in an abattoir for human consume. Serum samples from 120 dairy cows (60 pregnant and 60 non-pregnant) were collected, and indirect fluorescent antibody test (IFAT) was performed to detect anti-T. gondii antibodies by considering positive animals with titers ≥50. Serologic results from cows showed 29.1% (35/120), which 29 (48.3%) e 6 (10,0%) were from pregnant and non-pregnant cows, respectively. This revealed a risk 8.4 times-higher of positively in pregnant than non-pregnant cows (OR=8.4, 2.91<OR<25.6, P<0.0001). There was a statistical difference in the anti-T.... |

| ABSTRACT: The presence of anti-Neospora caninum antibodies in beef cattle slaughtered in the northern region of the state of Paraná, Brazil, was evaluated. A total of 401 blood samples were collected; 281 samples from the municipality of Rolândia and 120 from the municipality of Borrazópolis, between April 2015 and November 2016. Of the total samples, 289 were from females and 112 from males, aged one and a half to eight years. Indirect fluorescent antibody test (IFAT) was performed, using a cut-off of 1:100. Variables were tabulated for statistical analyses (Fisher’s exact test and chi-square tests, p≤0.05). The analysis showed that of the 401 samples, 37 were positive for N. caninum, indicating a prevalence of 9.2 %, and observed titers were 1:100 (16),... |
