| Abstrakt: | Objective: Determining Leptospira spp . antibody seroprevalence in an apparently healthy population and in groups at risk plus their associated factors in the town of Villavicencio in the Meta department of Colombia Materials and Methods: A cross-sectional epidemiological model was used (subjects being selected by convenience sampling). Blood-samples were obtained by cubital puncture from (n: 503) people, consisting of 230 first semester students from different programmes at the Universidad de los Llanos and 273 people corresponding to 8 groups at risk. Information regarding risk factor was obtained from interviewing the 503 people. A commercial indirect ELISA kit (Pambio) was used for determining IgM antibodies. Results: Seroprevalence was 5,2 % in the low risk group. There was 19 % seroprevalence for groups at risk, 7 % for the group of people working in slaughterhouses, 17 % for vets and small animal clinic assistants, 17 % for students in their last year of Veterinary Medicine and Zootechnia, 21 % for people milking cows on dual-purpose farms, 23 % for people working in rice-fields, 35 % for people working on pig-farms and 48 % for those working on fish-farms. Three factors were found to be associated: rural social level, having a pet dog and coming into contact with rodents in the workplace. Conclusions: A high seroprevalence for Leptospira spp was found in the groups at risk, people working on pig-farms and fish-farms being those most affected. There was a 1,86 relative risk in both groups indicated as having a greater risk of contagion amongst the population suffering occupational exposure. |
