Reversibility of the effect of 2,2-dipyridyl on <i>L. (V.) braziliensis</i> proliferation.

<p>Parasites were incubated with 100 µM iron chelator and resuspended in Schneider's fresh medium after 24 h or 48 h of treatment. Cell density was determined daily for eight days by counting with a hemocytometer. Proliferation of parasites cultivated in the control medium as well as the growth of parasites continually cultured in the presence of 100 µM 2,2-dipyridyl were also monitored. Bars represent means and standard errors obtained from three independent experiments.
