[Influence of Eimeria acervulina duodenal coccidiosis on intestinal absorption of lysine and on the movement of water and electrolytes].
The absorption rate of 14C L-lysine and net flux of water and mineral ions (Na+, K+) were studied in 4-week-old male chickens infected with Eimeria acervulina (10(6) sporulated oocysts/chicken). Intestinal coccidiosis significantly decreased absorption rate of 14C-lysine. This effect was particularly pronounced in the jejunum. Net flux of water was also modified: its absorption was decreased in the middle and distal small intestine. In the duodenum a net absorption of water was converted to a net excretion. These effects were accompanied by an increase in tissue water content and in secretion rate of Na+ and K+.
