| Abstract: | The respiration of miracidia of Schistosoma mansoni and the Japanese, Philippine, and Formosan strains of S. japonicum was measured in the presence and absence of 0.001 m glucose at 1 and 5 hr after hatching. Aging increased the oxygen consumption of miracidia of S. mansoni and the Japanese and Formosan strains of S. japonicum when respiration was measured in buffer without glucose. However, aging did not affect the Philippine strain. The Formosan strain utilized more oxygen in the presence of glucose than did the other three schistosomes studied. In the presence of glucose the Philippine strain used less oxygen than did the Japanese strain or S. mansoni miracidia. |
