Abstract

Leptospirosis, brucellosis and toxoplasmosis are widely-distributed zoonosis, being the man an accidental participant of their epidemiological chains. The aim of this paper was to make a seroepidemiological report and identify occupational and environmental variables related to these illnesses in 150 workers in a slaughterhouse in the Northern region of Paraná. For the diagnosis of leptospirosis a microscopical seroagglutination test was applied; for brucellosis, the tamponated acidified antigen test and the 2-mercaptoetanol tests were used, and for toxoplasmosis the indirect immunofluorescence reaction test. For each employee an epidemiological survey was filled, which investigated occupational and environmental variables which could be associated with these infections. Positive results for leptospirosis were found in 4.00% of the samples, for brucellosis in 0.66% of samples and toxoplasmosis in 70.00%. From the three diseases researched, only the results for leptospirosis suggest occupational infection.<br>A leptospirose, brucelose e a toxoplasmose são zoonoses de ampla distribuição, sendo o homem participante acidental das suas cadeias epidemiológicas. O objetivo deste trabalho foi realizar levantamento soroepidemiológico e identificar variáveis ocupacionais e ambientais relacionadas a estas enfermidades em 150 trabalhadores de um frigorífico da região Norte do Paraná. Para o diagnóstico de leptospirose foi realizada a prova de soroaglutinação microscópica; para a brucelose, a prova do antígeno acidificado tamponado e do 2-mercaptoetanol e para toxoplasmose, a reação de imunofluorescência indireta. Para cada funcionário foi preenchido um questionário epidemiológico que investigou variáveis ocupacionais e ambientais que poderiam estar associadas a estas infecções. Resultados positivos para leptospirose foram encontrados em 4,00% das amostras, para brucelose em 0,66% das amostras e para toxoplasmose 70,00%. Das três enfermidades pesquisadas, somente os resultados obtidos para leptospirose sugerem infecção de modo ocupacional
