Identification and possible role of D-mannitol and 2-O-methyl-chiro-inositol (quebrachitol) in Eimeria tenella.
Analysis of polyol extracts from various stages of Eimeria tenella has revealed the presence of mannitol and 2-O-methyl-chiro-inositol (quebrachitol). Previously, both compounds had been found almost exclusively in plants, and in the case of mannitol in a few species of bacteria. Identification was achieved by various analytical techniques including nuclear magnetic resonance (NMR), capillary gas-liquid chromatography (GLC), and GLC-mass spectrometry. Unsporulated oocysts contain a high level of mannitol (300 mM) which diminished during sporulation to 10 mM in sporulated oocysts.
