In a survey of intestinal canine zoonotic helminths in Nairobi, 156 do
gs were autopsied. Of these, 10% were infected with Echinococcus granu
losus, 88% with Ancylostoma caninum, 415% with Dipylidium caninum and
3% with Toxocara canis. All the infected dogs with E. granulosus origi
nated from around abottoirs in Dagoretti. The risk of infection in man
with hydatid disease is considered to be high around Dagoretti and co
ntrol measures are recommended.
