Resumen
Leptospirosis is an endemic disease recognized in Mexico since 1920; in Jalisco State there is no reference on the incidence of this suffering. This work studies the seroprevalence to leptospirosis in 112 workers of two groups of risk of Guadalajara City: 77 of them from the slaughterhouse, and 36 of water supply and sewage system. Was taken to them 5 ml of blood, which was processed by microagglutination for degree of antibodies against leptospiras selected by random procedures. It was investigated seroprevalence to leptospiras, mainly serotypes, age and time in the work. Results: in the workers of the water supply and sewage system the prevalence was 36.1% and for those in the slaugterhouse, 24.7%. L.canicola and L. Pomona were the serovares that predominated. The found prevalence rates in this study are higher to the considered ones for urban population in Mexico City, than occurs between 2 at 4% and for other study in similar groups of risk in other countries. Finally it concludes that in Jalisco State leptospiras circulates in these groups of risk and is a good example of its presence. We need programs of specific protection through the immunization against the suffering, as well as the observance of the measures of protection are required suggested by the Mexican official norm.
