Zmiany w jelicie karpi (Cyprinus carpio L.) spowodowane obecnością Cysticercus dilepidis campylancistrotae (Aubert)

Changes occurring in the intestine of Cyprinus carpio L. are described as a result of the attachement of Cysticercus dilepidis campylancistrotae (Aubert) both to the mucous membrane and beneath its surface. In the latter case, histologic method were used for examination. It had been found that the parasite is not enclosed by the connective capsule and does not give rise to any appreciable cell infiltrate, but it leads to marked congestion and mechanical damage to blood vessels; single nodules contained occasionally 2-3 parasites: mostly, they were separated by the host tissues. The authors believe that the described intestinal changes have no seizable adverse influence on the condition and body weight increase of fishes.
