title: 1H- and 13C-NMR spectroscopic study of glucose metabolism in eggs of Angiostrongylus cantonensis during their development.
abstract: 1H- and 13C-nuclear magnetic resonance (NMR) spectroscopy was used to study aerobic glucose metabolism in eggs of Angiostrongylus cantonensis in an NCTC-109 medium supplemented with fetal calf serum. Without any pretreatment of the spent medium, we were able to identify and quantitate, by NMR, the end-products of glucose metabolism in eggs after cultivation for 2, 4, and 8 days. We demonstrated that A. cantonensis eggs took up glucose rapidly; among the major end products were found lactic acid, acetic acid and alanine. The eggs are parasitic in a sense that the energy metabolism in them is dependent mainly upon the energy source present in outer medium.
