Changes in the blood glucose and liver glycogen contents of healthy and trypanosome infected fish, Clarias batrachus, following intramuscular injection of glucose solution.

Changes in the blood glucose and liver glycogen contents in healthy and trypanosome infected fish Clarias following the intramuscular injection of glucose solution showed a rise in both the parameters within an hour. Peak levels were obtained almost simultaneously by the 2 groups in both the tissues. However, there was a rapid rise and an equally rapid decline of increased carbohydrate contents in the trypanosome infected fishes. This is attributed to the rapid consumption of sugars by the trypanosomes in diseased fish, besides replenishment of sugar reserves of various body tissues from the liver via blood.
