ABSTRACTObjective. To determine seroprevalence and risk factors associated to Neospora caninum in non-vaccinated dairy cattle against infectious agents of reproductive syndrome in the municipality of Pasto, Colombia. Materials and methods. Farms over 2527 meters over sea level were selected, a total of 238 serum samples of Holstein cows were collected and analyzed using the indirect ELISA test to determine N. caninum seropositivity. An epidemiological survey was realized in each herd which included variables related to health and management measures of cattle. A multivariate analysis of binary logistic regression was used with a confidence interval of 95% (p<0.05) using SPSS19® program. Results. The estimated prevalence of N. caninum was 76.9%. The risk factors associated to neosporosis infection in the analyzed farms are as follows: residues of abortions generally left outdoors and not buried (OR 3.81, 95% CI 1.5 - 9.6); dogs fed with leftovers (OR 15.44 IC 95% 1.94-123.22) and bulls allowed to mate with cows (OR 19.68, 95% CI 2.34 - 165.52). Conclusions. The high prevalence of N. caninum and the low abortion rate in dairy herds of the municipality of Pasto corroborated no existence of the disease in all animals serologically positive, but it did suggest that at some point in their lives they were exposed to N. caninum. From the identified risk factors in this study, recommendations can be provided for an effective control of reproductive diseases like Neosporosis present in this region.

The objective of this study was to conduct a seroepidemiological survey of Chlamydia abortus infection in dairy cattle herds. A total of 303 blood serum samples were collected from 24 property in Vale do Ipanema microregion in the state of Pernambuco, Brazil. For the diagnosis of C. abortus infection, a commercial enzyme immunoassay kit (ELISA) was used. A prevalence of 34.0% (103/303; 95% CI: 28.7%-39.7%) of infected animals was identified. In 79.8% (19/24) of the properties, at least one infected animal was detected. The risk factors identified were: semi-intensive system (OR = 3.47, p ≤ 0.000), extensive system (OR = 8.14; p ≤ 0.000), supply of water in troughs and directly at the fountain (OR = 2.29, p = 0.002), pasture rent (OR = 1.72, p = 0.041), use of artificial insemination (AI) (OR = 3.07, p = 0.002), and use of AI associated with natural mount (OR = 2.22, p = 0.003). The occurrence of C. abortus infection in dairy cattle in the state of Pernambuco, Brazil, was recorded for the first time. It is concluded that the infection by this agent is present in the analyzed herds and that hygienic and sanitary management measures based on the identified risk factors should be implemented to avoid reproductive losses and losses to the producers.
