The parasites were found both in host's alimentary canal and extraintestinal position. R laevis were found between I 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 R laevis penetration was observed, it was not completely capsule formation.eninfo:eu-repo/semantics/closedAccessAcanthocephalaPomphorhynchus laevispathologytenchTinca tincaArticle155271732-s2.0-1642460615N/AWOS:000220918200002Q4
