Abstract
Toxoplasmin skin test survey showed 51% incidence in 2 cottages at Gracewood Training School for Mental Defectives, Gracewood, Georgia. The cottages of high incidence included patients assisting in care of farm animals. Two large animal herds maintained for food at the Training School showed 83:3% incidence in cattle and 68.3% in swine (1:16 or more titer with methylene blue dye test). High incidence of toxoplasmosis in 2 cottages was related here to association with infected animals, not to consumption of infected meat. The localized endemic area of toxoplasmosis provided a means of investigating epidemiology of this infection under natural conditions.
