Resumo: | 17.993 bovine sera from Minas Gerais state were analized through microscopic agglutination test to check the prevalence of antiLeptospira interogans agglutinins in three groups of animals from 1998-2002. To recognize the forms of animal production in different municipalities it was used the indicators wich reflect the demographic systems between steer/cow ratio and caracterized the risks areas of infecction by L. interrogans. The most frequently observed serovars were hadjo (Norma) (22.66%), hardjo (OMS) (18.26%), hardjo (hardjoboivis) (13,79%) and wolffi (9,73%). Analysing the frequency of anti Leptospira interrogans agglutinins according to the types of exploration it is ended the relation between those frequencies and forms of production starter reasing (calves), re-criate, complete cycle and fattening (termination). The most of higher risk counties of infection by hardjo (OMS), hardjo (Norma), wolffi and pomona are dedicated of re-criate and fattening (termination). The most of lesser risk counties of infectionof the same sorotypes are in the starter reasing (calves). |
