title: [Eco-epidemiology of visceral and cutaneous leishmaniasis in the Arab Republic of Yemen. II. A survey using intradermal reaction to leishmanin in a zone of mixed infestation with Leishmania tropica, L. donovani and L. infantum].
abstract: Frequency distribution of leishmanin test survey in Dhamran valley around Taez (Yemen Arab Republic) is reported. It was carried out on 174 school children from 6 to 12 years old. Three schools located at 950 m, 1,100 m and 1,430 m of altitude were visited. The maximum of positivity is observed in the lower range where L. tropica, L. donovani and L. infantum are rife. In the upper valley, where cutaneous leishmaniasis is rare and visceral leishmaniasis absent, the rate of positivity is a little bit lower. The conjugated influence of the three parasites is suggested.
