RESUMO
Recently attention in human medicine has been drawn to encephalitozoonoses. Increased liability to develop the infection is found in particular in people with an impaired immunobiological condition. Evidence of this are more numerous infections in AIDS patients. However, the impact of encephalitozoonoses cannot be ruled out in other groups of patients. This calls however for specific aimed investigations. The authors examined 98 sera of employees of a slaughterhouse for encephalitozoonosis. Five sera (5.1%) were positive. Sera of 92 forestry workers, 22 dog breeders and 150 blood donors were negative. In future it will be necessary to focus attention on seropositive subjects in conjunction with the possible transmission of the disease from animals to man.
