Detection of anti-Neospora caninum antibodies in dairy cattle in municipality Tiros, Minas Gerais

Abstract

Neosporosis is considered one of the main diseases causing abortion in dairy farming worldwide. Neospora caninum is identified as a causal of reproductive problems and neurological disorders. The goal was to detect anti-Neospora caninum antibodies in cow, in the municipality of Tiros, MG, besides establish the possible risk factors involved. A total of 100 serum samples were collected from cow in 20 different rural properties with diagnosis based on serology by Enzyme-Linked Immunosorbent Assay (ELISA). Descriptive statistical analysis (absolute and relative frequencies) and determination of risk factors by the non-parametric Odds Ratio test for two independent samples was performed, considering a significance level of 5%. The detected occurrence was 36% (36/100). The risk factor identified was the lack of assistance from the veterinarian (P < 0.0451). All properties (100%, 20/20) evaluated had a recent history of reproductive changes, such as abortion, repetition of heat and / or retention of fetal attachments, therefore, epidemiological studies are needed to identify the possible etiological agents involved to minimize possible economic impacts, as well as the permanent and vigorous performance of the veterinarian in the rural properties of the municipality
