title: Altered distribution of 109cadmium in mice during viral infection.
abstract: The distribution of the toxic heavy metal cadmium (Cd) was studied in Coxsackie virus B3 (CB3)-infected Balb/c mice by whole-body autoradiography and gamma-counting. The distribution of 109Cd was studied 4 days post CB3-inoculation and 10 min after intravenous injection of 0.21 microgram of Cd/kg body weight. Whole-body autoradiography results showed that the distribution of 109Cd is greatly changed during this viral infection. This newly discovered distribution was mainly visible as a greatly increased accumulation in the renal and adrenal cortices. After impulse counting of selected organs it was found that the normal accumulation of 109Cd in the kidneys (184,354 +/- 30,961 c.p.m.) was increased by 47% (P less than 0.05) during CB3 infection (270,503 +/- 54,780 c.p.m.). In contrast to healthy animals, some infected mice showed accumulation of 109Cd in the spleen. These results show for the first time that an invading micro-organism can change the distribution of an environmental pollutant.
