PREVALENCE AND SPECIES OF Fasciolopsis buski IN VIETNAM

PERPOSE : To report prevalence and species of Fasciolopsis buski in Vietnam. METHOD : Stool examination by Kato - Katz technique for detection prevalence of fasciolopsiasis, and identification species by morphology and molecular method. RESULT: On 10,540 stool samples were examined in 14 provinces and adult worms of Fasciolopsis collected from patients in other 3 provinces . The result showed that 13/14 provinces have been patients infected Fasciolopsis . However, fasciolopsiasis was determined distribute in 16 provinces with prevalence of 1.23% in average (from 0.16% to 3.82%). Adult worms were identified as Fasciolopsis bus ki by morphology and confirmed by molecular analysis using of 1950 bp - 18S ribosomal RN A(18S rRNA) as genetic marker.
