ANDRES GEOVANNY, Zuluaga León. RISK FACTORS ASSOCIATED TO LEPTOSPIROSIS IN BOVINE CATTLE RANCHES IN PEREIRA BETWEEN THE YEARS 2002 AND 2005. Investig. andina [online]. 2009, vol.11, n.19, pp.109-117. ISSN 0124-8146.

Introduction: the serological prevalence of the bovine leptospirosis disease was analyzed in the rural area of the municipality of Pereira, State of Risaralda, Colombia, in order to find out its actual situation. Methods: during this period, 1789 heads of cattle in 158 cattle estates, coming from 88 different farms, were evaluated through a technique of microscopic agglutination of live antigens, Results: the results show a global prevalence of leptospirosis of 16.4% in animals and 32.5% in estates. The predominant serovar was hardjo with 45.7% and the antibody titles found were at very low levels between 1:50 (51.5%) - 1:100 (45.3%). Discussion: the risk factors that were found are the presence of rodents, the proximity to garbage disposal areas, areas with humid climates and presence of wetlands in pastures, poor management of disinfection in the property and the presence of other animal species close to cattle in the farm.
