Some Aspects of Carbohydrate Metabolism in the Cercariae of SCHISTOSOMA MANSONI Sambon, 1907

Abstract

dc:description.abstract

<p>Cercariac of <em>Schistosoma mansoni</em> were studied for glycogen utilization, uptake of glucose from solution, lactic acid production, and respiration.</p> <p>Using the anthrone method of determination of carbohydrate, the amount of glycogen used by a single cercaria in 4 hours is determined as 43.2 x 10<sup>-4</sup> μg ± 6.6 x 10<sup>-4</sup> μg.</p> <p>Glucose was not observed to have been used from solution under the conditions of the experiment, even in the presence of trehalose. The determinations were made by the Glucostat method.</p> <p>After deproteinization and desugarization, aliquots of supernatant from cercarial suspensions were analyzed for lactic acid using p-phenylphenol and sulfuric acid. The production of significant amounts of lactic acid by the cercariae was not observed.</p> <p>Respiration was measured on a Warburg constant volume respirometer. The amount of oxygen used by a single cercaria in 4 hours is determined as 29.0 x 10 <sup>-4</sup> μl ± 3.4 x 10<sup>-4</sup> μl. The amount of carbon dioxide produced by a single cercaria in 4 hours is determined as 34.6 x 10 <sup>-4</sup> μl ± 4.6 x 10 <sup>-4</sup> μl. A respiratory quotient of 1.9 ± 0.08 was obtained.</p>
