[Killing Effect of Carpesium abrotanoides on Taenia asiatica Cysticercus]

The cysticerci of Taenia asiatica were cultured in vitro with different concentrations of water decoction of Carpesium abrotanoides (20, 40, and 60 mg/ml). The killing effect of C. abrotanoides on T. asiatica and the morphological change of cysticerci were observed under microscope 24 hours post-culture. The water decoction of C. abrotanoides showed significant killing effect on the cysticerci. The mortality of the parasites(95.0%, 57/60) was highest in 60 mg/ml group. The dead body of cysticercus shows shrunken with the enlarged scolex, and sucker tissue degenerated.
