Survival days of BALB/c mice either infected with T. gondii or treated orally with dexamethasone. Each group contained 10 mice. The Dexa-treated group of BALB/c mice were treated with 10 mg/L of dexamethasone in drinking water, 4~8 weeks after the beginning of the experiment. The Toxo-infected group of BALB/c mice were orally infected with 25 cysts of a 76K strain of T. gondii, and then evaluated for 8 weeks. The Toxo/Dexa-treated group, consisting of Toxoplasma-infected BALB/c mice, was treated with 10 mg/L of dexamethasone in drinking water for 4-8 weeks, beginning at 4 weeks PI. The data are representative of 1 of 2 separate experiments.
