Abstract

The complement fixation and indirect immunofluorescence tests for antibody to Toxoplasma gondii were applied to 347 sera taken from 54 veterinarians and their assistants, 90 slaughtermen and 208 blood-donors employed in commerce and industry. The incidence of antibody among blood-donors (23-25 per cent.) was similar to that in veterinary workers (22 per cent.) and was no greater than levels recorded in populations elsewhere. The incidence of antibody among slaughtermen, however, was significantly higher (47 per cent.) than among the other two groups. The serum tests were also applied to 50 dogs and 66 cats from 51 households in which one or more cases of toxoplasmosis had been diagnosed in humans, and to 113 sera from stray cats. Antibody was detected in 12 per cent. of the dogs, 11 per cent. of the domestic cats and 19 per cent. of stray cats. In no instance was it possible to conclude firmly that infection of humans had followed infection of pets. Examination of 37 cat stool specimens failed to reveal the oocysts of Toxoplasma gondii. The significance of the findings are discussed in relation to the known epidemiology of the disease and simple control measures advocated elsewhere are reiterated.
