Feeding selenium (Se) activated adult worm expulsion and reduced worm ATP levels. Mice fed a Se-adequate or Se-deficient diet were reinoculated with H. bakeri infective larvae, and one set of infected Se-deficient mice were fed a Se-adequate diet at 10 days after reinoculation and sacrificed 4 days later. (A) The number of adult worms recovered from the small intestine was determined. Bars with different letters show significantly different results; P < 0.001. (B) The ATP levels of adult worms recovered were significantly reduced when mice were fed a Se-adequate diet; *, P < 0.001. Data are expressed as the means ± SD (n = 5). ND, not determined.
