Intestinal uptake of nutrients in normal and malnourished animals infected with Giardia lamblia

The effect of malnutrition on the uptake of nutrients was studied in Swiss albino mice infected with Giardia lamblia. The moderate deficiency (8% protein-deficient diet) was observed to enhance the uptake of nutrients like glucose and alanine, whereas in severely malnourished (3% protein-deficient diet) animals the uptake was significantly decreased (p less than 0.001). G. lamblia infection in mice decreased the uptake of nutrients and this recovered slightly with the recovery of infection. The combined effect of moderate protein deficiency and infection lowered the enhanced uptake observed in moderately malnourished animals to a significant level (p less than 0.001). In severely malnourished animals, infection with G. lamblia showed further deleterious effects on the uptake of nutrients.
