[Toxoplasmosis in agriculture workers exposed to the risk of contamination].

Five-hundred-and-eighty-eight cattle and agricultural workers were surveyed. One-hundred-and-fifty of them were randomly selected, and they underwent leukograms and absolute eosinophil counts for enabling the study of their hematologic state. A 55% positivity rate was obtained among patients studied through the toxoplasmin intradermoreaction technique from Czechoslovakia. Historical and morphologic aspects, biological characteristics, evolutive cycle, pathologic characteristics, clinical manifestations, as well as the epidemiology of Toxoplasma gondii are reviewed.
