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.

Salmonella Dublin is a causative agent of a gastrointestinal bacterial infection prevalent in many cattle herds worldwide. Hence, the goal of this research was to evaluate the prevalence of Salmonella Dublin carriage in fecal and milk samples from dairy cattle from Algeria, and to investigate potential risk factors associated with the presence of S. Dublin antibodies. A total of 307 cows from 39 farms were analyzed in this study. Bacteriological and immunological methods were used to isolate and detect S. Dublin antibodies in feces and cow’s milk. Antimicrobial susceptibility testing was performed using the disc diffusion method. Logistic regression was used to study risk factors associated with S. Dublin antibodies. The bacteriological results showed the absence of S. Dublin and a prevalence of 0.97 % (3/307) (IC 95% 0 - 2.08)for S. Mbandaka. The immunological analysis of milk by the ELISA technique showed a prevalence of 36.33% (95% CI 30.44 - 42.22) for S. Dublin. Final multivariate regression models showed that the breed, the region and introduction of purchased cattle were associated with the presence of S. Dublin antibodies. This study is the first that reports the seroprevalence and risk factors associated with S. Dublin infection in Algeria and could be considered as a comparison point for further studies in Algeria.

<p>The objective of this study was to determine the prevalence of antibodies against <em>Leptospira </em>spp and their geographic distribution and to identify the risk factors associated with this disease in cattle herds with reproductive activity in the state of Paraná. A total of 14 163 females aged ?24 months originating from 1 926 herds that were not vaccinated against <em>Leptospira </em>spp were evaluated. To detect the <em>Leptospira </em>spp antibodies, all serum samples were submitted for a microscopic serum-agglutination test (MAT). An epidemiological questionnaire was performed at each farm visited to characterize the management practices and study the risk factors associated with the presence or absence of <em>Leptospira </em>spp. To perform geoprocessing, the geographical coordinates of each farm were recorded with a Global Positioning System (GPS), which were then used to create a map. The apparent prevalence of bovine leptospirosis in the herds was the parameter used to generate the final risk map. The apparent prevalences of seropositivity in the herds and animals in Paraná state were 54.28%(95%CI:52.05- 56.51) and 37.70%(95%CI:34.54-40.86), respectively. Multiple logistic regression analysis revealed that the risk factors associated with leptospirosis due to any serovar were the rental of grazing areas [OR=1.91(1.36-2.68)], presence of horses [OR=1.59(1.28-1.97)], presence of &gt; 20 females ? 24 months of age [OR=2.25(1.46-3.49)], presence of &gt; 49 bovines [OR=2.78(1.82-4.26)], purchase of animals for reproduction [OR=1.96(1.59-2.41)] and presence of calving pens [OR=1.32(1.04-1.68)]. Risk factors for leptospirosis due specifically to serovar Hardjo were the presence of &gt; 49 bovines [OR=3.05(1.94-4.80)], presence of &gt; 20 females ? 24 months [OR=2.38(1.50-3.79)], presence of horses [OR=1.87(1.45-2.43)], purchase of animals for reproduction [OR=2.14(1.68-2.72)] and rental of grazing areas [OR=2.22(1.54-3.21)]. Geographically, seropositivity to <em>Leptospira </em>spp by MAT identified the regions North/Northwest and Southwest in the state as the areas with a higher risk of disease occurrence.</p>
