Abstract

In the present study, the pathological changes of intestines from tench (Tinca tinca), naturally infected with Pomphorhynchus laevis, were investigated. The parasites were found both in host's alimentary canal and extra-intestinal position. P. laevis were found between 1 and 15 infected fish. On histological examination, it was noticed that all layers of the host intestine were disrupted at the attachment site of acanthocephalan. The response of tench at the attachment site of P. laevis was thickening of lamina propria and cellular infiltration. Although extension of the fibroblasts around P. laevis penetration was observed, it was not completely capsule formation.
