title: [Activity of digestive enzymes of thick-billed murre (Uria lomvia) and common murre (U. aalga) invaded by cestodes].
abstract: Activities of digestive enzymes (proteases, carbohydrases, acid and alkaline phosphatases) are determined in intestinal mucosa of the thick-billed and common murres Comparative analysis of the obtained results is performed for non-infected and for birds infested by cestodes. It has been established that at invasion by cestode Alcataenia armillaris (Cestoda: Tetrabothriidae), activities of carbohydrase and alkaline phosphatase in intestinal mucosa of the thick-billed murre decreases. Parasitizing of cestodes Tetrabothrius jaegerskieldi (Cestoda: Tetrabothriidae) in intestine of the common murre induces a decrease of saccharase activity. There is studied kinetics of desorption of enzymes from digestive-transport surfaces of the bird intestine. Peculiarities of firmness of enzyme fixation are established on the surface of intestinal mucosa of invaded murres. According to the obtained data, a decrease of the carbohydrase activities in intestine of infested murres is likely to be due to absorption of a part of enzymes hydrolyzing carbohydrates on the surface of cestodes.
