The relation between liver vitamin content and the duration of Schistosoma mansoni infection in mice.

To study some changes that take place in the liver after schistosomal infection, the level of five vitamins of the B-complex group was estimated in non-infected mice and in 8, 16 and 20 weeks after the exposure of mice to cercariae of Schisostoma mansoni. Schistosomiasis caused a decrease in the level of thiamine, pantothenic acid, and niacin, but did not affect the concentration of riboflavin and pyridoxine in the liver.
