Echinococcosis granulosus in stray dogs and Echino-IHAT in the hunters in Cairo, Egypt.

A total of fifty stray dogs of both sex and of different ages were examined for natural infection with Echinococcus granulosus after post-mortem. Three main intestinal helminthes were recovered. These were in descending order of abundance Dipylidium caninum, Toxocara canis and E. granulosus. The latter worm was demonstrated in eight of them (16%). The sera of three out of 21 dog-hunters (14.3%) showed positive Echino-IHAT. Two of the hunters suffered Enterobius vermicularis and one of them had Taenia saginata as well. But, the abdominal X-ray of the two hunters was more or less normal and did not show any hydatid cyst.
