RESUMO
Examination of fecal samples, collected after treatment with praziquantel, of the persons positive with opisthorchioid eggs residing in the northern provinces of Thailand, was carried out. Five adults Centrocestus were recovered in one sample from Doi Saket, Chiang Mai and one adult was found in another fecal sample from Wiang Pa Pao, Chiang Rai. The worms had 26-30 spines arranging in two rows around the oral sucker which agreed with the character of C. caninus. This is the first record of natural human infection with Centrocestus in Thailand.

Twenty-two yellow tree monitors (Varanus bengalensis) were trapped and transported from 5 provinces, namely Lampang, Phitsanulok, Kamphaeng Phet, Tak and Prachin Buri to look for the infective larvae stage of Angiostrongylus cantonensis. In 4 provinces all of the yellow tree monitors were infected with the infective stage larvae of A. cantonensis altogether. Twenty-one of the 22 yellow tree monitors (95.5%) in the five provinces were infected. Our results of this study extend our knowledge of natural prevalence of A. cantonensis in yellow tree monitors. The snail eating habit of the yellow tree monitor might possibly be the source of the larvae.
