Selenium (Se) deficiency did not affect the tissue stage but delayed clearance of H. bakeri infection in mice. Mice fed either a Se-adequate or Se-deficient diet were primed and reinoculated with 200 H. bakeri infective larvae. (A) At days 4 and 7 after reinoculation, mice were killed and worms recovered and counted. Results are means ± SEM (n = 5). *, results for Se-deficient group are significantly different from results for Se-adequate group; P < 0.05. (B) At days 12 and 21 after reinoculation, mice were killed and adult worms recovered and counted. Results are means ± SD (n = 5). *, results for Se-deficient group were significantly different from results for Se-adequate control group; P < 0.05. nd, no adult worms detected.
