Observations on the Morphology and Biology of <i>Echinococcus grantdosus</i> (Batsch, 1786) of Goat-Dog Origin

Abstract

In the present goat-dog material great individual variation was observed in the rostellar hooks. The strobila had either 3 or 4 segments in the gravid worms. The position of the genital pore was near the middle in the mature segments and posterior to the middle in the gravid segments. There were more testes anterior (average 27) than posterior (average 18) to the genital pore but they usually extended even behind the vitellaria. The cirrus sac was either elongated or pear shaped. The ovary was bilobed and uterus sacculated.
