Intestinal cestodes of stray dogs in Jordan

Five species of cestodes namely Echinococcus granulosus, Taenia hydatigena, Taenia pisiformis, Taenia ovis and Dipylidium caninum were recovered post mortem from 120 out of 173 stray dogs collected from the 5 governorates of Jordan during the period June 1979 to November 1980. Twenty-five of the examined dogs (14%) were found to be infected with E. granulosus, 79 (46%) with T. hydatigena, 14 (8%) with T. pisiformis and 5 (3%) with T. ovis. Dipylidium caninum was encountered in 33 (19%) of the examined dogs and infection with this parasite was significantly higher in males than in females. The parasites, except for D. caninum which was encountered in the ileum, were almost exclusively recovered from the duodenum and the jejunum. Single, double and triple infections with those cestodes were recorded.
