Abstract
We studied the activities both of digestive enzymes in the small intestine of the herring gull (Larus argentatus) and a tapeworm Diphyllobothrium dendriticum (Cestoda: Diphyllobothriidae) residing in the intestine. It was found that D. dendriticum infects the medial section of the small intestine of the herring gull. Such localization of D. dendriticum is caused by the maximal activity of proteases and glycosidases and by the high rate of membrane and cavitary digestion in this section. The activity of protease and glycosidase in gulls infected with D. dendriticum is decreased. The activity of proteases in the fractions desorbed from the tegument surface of D. dendriticum is significantly higher than that of glycosidases.
