RESUMEN
Brucellosis is a zoonotic disease that exists worldwide. Several studies were conducted in different governorates, e.g. Menofia, Dakahlia, Giza, Assiut, to estimate the prevalence of brucellosis, but little is known about the problem in Sohag Governorate. The aim was to estimate the frequency of brucellosis in farm workers in Sohag Governorate using ELISA test and to treat positive cases. This study involved 141 persons [91 persons from three farms in Sohag Governorate [high risk group] and 50 persons, who have no contact to animals [control]]. Through this study complete clinical examination, ultrasound examination and complete blood count and ELISA test for brucellosis were done to all persons. The results revealed that the frequency of seropositivity to brucellosis was found to be 12% in the three farms as a whole [13.5% in Faculty of Agriculture Farm, 13% in El-Dyabat Farm and 0% in Shandaweel]. It was concluded that brucellosis is not uncommon among farm workers in Sohag Governorate. Animal vaccination and regular examination for detection of diseased animals was recommended. Health education of workers is of great importance to minimize the transmission of the disease
