ECHINOCOCCOSIS IN LIBYA .3. FURTHER-STUDIES ON THE PREVALENCE OF ECHINOCOCCUS-GRANULOSUS IN DOGS

Of 92 dogs examined for Echinococcus granulosus at five sites in Libya from April 1985 to September 1988 33 (35.9%) were infected, the prevalences ranging from 60% (Zawiyah) and 52.0% (Tripoli) in the north-west, to 28.6% (Benghazi) and 28.5% (Darna) in the north-east. None of eight dogs at Al-Kufra, in the south-eastern desert, were infected. Twenty dogs each had two to 200 worms, nine had 201-1000 worms and four each had over 1000 worms (one dog in Tripoli had 17 120 worms). Most infections were seen in dogs aged three to four years; 45.4% of bitches and 35.4% of males were infected.
