Innate immune defence mechanisms of tench, Tinca tinca (L.), naturally infected with the tapeworm Monobothrium wageneri

Summary A histochemical and ultrastructural investigation of the cellular inflammatory response within the intestines of tench Tinca tinca L. naturally infected with the caryophyllidean cestode Monobothrium wageneri was conducted and the data obtained compared to those in uninfected counterparts.

Description
Summary:Summary A histochemical and ultrastructural investigation of the cellular inflammatory response within the intestines of tench Tinca tinca L. naturally infected with the caryophyllidean cestode Monobothrium wageneri was conducted and the data obtained compared to those in uninfected counterparts. Cestode infections within the intestines were evident through the appearance of raised inflammatory swellings induced by the deep penetration of their scolices into the intestinal wall. Cestodes typically attached in tight clusters, inducing a massive hyperplastic granulocyte response of mast cells and neutrophils, which were significantly more numerous (P
