“lazy”. Since there is plenty of glucose and oxygen available, they rely solely on glycolysis to the stage of<br />

pyruvate for their energy supply [12]. Their glycolysis proceeds at an amazing rate, which is about fifty<br />

times faster than in the cells of the human host [43]. This fast rate is a necessity because only two<br />

molecules of ATP are generated per molecule of glucose instead of the thirty-six produced <strong>by</strong> complete<br />

oxidation. These findings led to the proposal that inhibitors of trypanosomal glycolysis might be turned<br />

into drugs. Support for this idea comes from in vitro experiments where salicylhydroxamic acid (SHAM)<br />

was used to bring the parasite under anaerobic conditions, after which glycolysis was<br />
