The prevalence of
Strongyloides stercora/is
infection was studied in the rural and urban popu-
lations of 19 provinces of Northeastern Thailand. A total of 1233 fecal samples was collected from July
to September 2002 and examined using agar plate culture method. The overall prevalence of
S. sterco-
ra/is
was 23.5 per cent with the highest infection rate in Kalasin Province (61.0%), predominantly
among 60 year olds and older (28.0%), and in males (32.8%). The factors associated with
Strongyloides
infection were sex (males) and age (the over 19 year-old age group).
Conclusion :
S. stercora/is
infection remains highly prevalent among the population of north-
eastern Thailand as confirmed by the agar plate culture method. The authors recommend that a pro-
gram for effective strongyloidiasis control should have a justifiable priority.
Key word :
Strongyloides stercora/is,
Northeastern Thailand, Agar Plate Culture
