Overview

The aim of this study was to compare the disease seroprevalence in two different dairy cattle and our goal was to identify risk factors and their impact in disease prevalence.[...]the questions were address regarding the mixing with other species, the presence of dogs, irrigation and drainage systems, the presence of swamps, topographical location, age, implementation of the rat control program, vaccination program against leptospirosis.A Chi-square test was conduct to investigate the association between the exposure to most important risk factors and the disease outcome [2].The serological titres have approximately normal distribution in both farms, however there is a significant difference between the two farms, in the R04 farm the number of positive individuals ranged from 2 ± 1.58 (mean ± standard deviations) while for the second farm they ranged 5.7 ± 2.8 animals.[...]we are 95% confident that the odds ratio in the population (from where the sample was obtained) would be between 2.83 and 12.21.Since the odds ratio confidence interval does not include the null value (i.e. 1), and the p-value (<0.001) is less than 0.05, the conventionally used criterion to evaluate p-values, the association between exposure and outcome is statistically significant at 5% level of significance [1, 2].
