[Epidemiological investigation of Taenia saginata asiatica in Duyun, Guizhou and detection of amino acids and elements of adult worms].
OBJECTIVE
To study epidemiological factors of taeniasis and to detect amino acid and element components of adult worms in Duyun of Guizhou Province.


METHODS
1. Traditional methods were used for epidemiological investigation. 2. Automatic amino acid analyzer and bioassay were applied for the detection.


RESULTS
Among 70 persons with clinical symptoms, 25 patients (24 men and 1 woman) were found to have adult taenia worms in their faeces after taking Areca catechu L. and other drugs. Sixteen amino acids and 12 elements were determined in adult worms.


CONCLUSIONS
Duyun area in Guizhou is a highly endemic area of taeniasis. The pathogenic parasite is identified as Taenia saginata asiatica. Its clinical symptoms are similar to that of Taenia saginata saginata.
