Abstract
Salts of cadmium, lead, mercury, and nickel given orally to mice increased encephalomyocarditis virus-induced mortality rates. Although lead was the least toxic of the 4 metals, it enhanced the mortality the most. Concentrations of mercuric chloride as low as 0.01 ppm intensified the mortality; a minimal concentration that resulted in no effect was not ascertained. Zinc deficiency caused pronounced retardation of growth in young mice, but it did not influence mortality due to encephalomyocarditis virus.
