Dynamika inwazji Cysticercus dilepidis campylancistrotae (Aubert) u karpi hodowanych (Cyprinus carpio L.)

The invasion was observed in fish ponds of Chojnów region (Lower Silesia). The material obtained prompts an assumption that fishes may be infested by the parasites as early as in the first months of life this being indicated, in authors' opinion, by the presence of small-sized parasites in the gallbladders of examined fishes, beginning from July. The authors found the gravity point of invasion, in the time of summer to autumn, to shift from the gallbladder to the intestine and admitted the possibility of parasite transmission from one organ to the other, stressing, however, that the former is the main environment of Cystrcercus dilepidis campylancistrotae in carp.
