ABSTRACT
Effect of both cumin black seed Nigella sativa and Cinchona species aqueous extracts
on both the cestode Polyonchobothrium clarias and the nematode Paracamallanus
cyathopharynx were investigated in vitro. Results showed that cumin black seed extract
changes in morphology of the anterior region of worms, immature and gravid proglottids
beside their eggs. After 3 hours of treatment by black seed extract the adult cestode and
nematode were died. In conclusion, this study recommends by using cumin black seed as a
new antihelminthic medicament against these worms of fish while Cinchona species
affected only on the larvae of nematode worms.
