    Abstract:
    Excretory end-products of adult Schistosoma japonicum, fed D-[13C6]glucose in vitro under aerobic and anaerobic conditions, were studied using 1H- and 13C-nuclear magnetic resonance (NMR) spectroscopy. The glucose in the medium is degraded to produce lactate and alanine aerobically and succinate and acetate as well as lactate and alanine anaerobically. Succinate and acetate have not been previously recorded as excretory products resulting from the metabolism of glucose for schistosomes. The presence of [13C3] and [2,3-13C2]lactate, and [1,2,2'-13C3] and [2,2'-13C2]succinate as end-products suggests that a partial reversed tricarboxylic acid (TCA) cycle is active in adult Schistosoma japonicum under anaerobic conditions. The physiological role of this pathway in adult schistosomes remains obscure.
