[Intestinal helminths in Bangkok stray dogs and their role in public health (author's tranls)].

Feces examination of 107 stray dogs in Bangkok, Thailand, on intestinal helminths showed the following rates: hookworms 100%, Trichuris vulpis 54.2%, Toxocara canis 6.5%, Gnathostoma spinigerum 2.8%, Spirocerca lupi 17.8%, Diphyllobothrium mansoni 1.9%, and Opisthorchis viverrini 1.9%. Out of these species hockworms (especially A. braziliense), T. canis, G. spinigerum, and D. mansoni are important sources of human cutaneous or visceral larva migrans, the latter two being special parasites of the Far East. Also O. viverrini is limited in its distribution to the Southeast Asian region; it is typical liver fluke of man in Thailand. The infection rates with these helminths show, that dogs may play a significant role as parasite reservoirs in this country.
