Following in vitro culture of female worms, increasing levels of dietary pectin were associated with increasing release of eggs. This inactivation step significantly reduced the release of water-soluble and oxalate-soluble pectins (data not shown). Species variability in boron requirement is correlated with cell wall pectin. All regression lines were statistically significant for pectin but none were statistically significant for cellulose (see text for details). However, an analysis of pectin and pectin methyl esters in developing and maturing soybean seeds has not been reported. In vitro egg production increased linearly whereas in vivo per capita egg production increased then declined with increasing concentrations of pectin. Two classes of fibre exist : cellulose and lignins comprise the insoluble fraction while pectin, guar gum and hemicellulose form the soluble fraction. Water-soluble fibre (pectin) or water-insoluble fibre (cellulose) was added to the diet separately at 5, 10 and 20 % levels. We suggest that pectin promoted parasite establishment through effects on bile sequestration in the lumen. Site specific changes in pectin esterification may facilitate cell wall folding during desiccation. Yet this pattern was not observed in vivo, where per capita egg production peaked at the 10 % pectin concentration, but was very low in mice fed 20 % pectin. Thus, increasing concentrations of pectin and cellulose could also be advantageous to the survival and reproduction of the parasite if intestinal morphology responds similarly in infected mice. Effects of differing purified cellulose, pectin and hemicellulose fiber diets on mucosal morphology in the rat small and large intestine. Parasite establishment was elevated in mice fed 20 % pectin, but was unaffected by cellulose concentration. These examples are from corpora and from sources on the web.
