Abstract
Taenia solium, T. saginata, and T. asiatica are cestode pathogens causing
taeniasis in humans. Houseflies can transfer Taenia eggs to food. However,
houseflies are thought to carry only small numbers of Taenia eggs, sometimes
fewer than 10. Although several PCR-based methods have been developed to
detect Taenia DNA, these require more than 10 eggs for adequate detection. We
developed a multiplex PCR method with high specificity for the discrimination
among the eggs of the three Taenia species, T. solium, T. saginata, and T. asiatica,
using 18S ribosomal DNA (rDNA) as a genetic marker. This technique was found
to be highly sensitive, capable of identifying the Taenia species from only one egg.
This multiplex PCR technique using 18S rDNA specific primers should be suitable
to diagnose Taenia eggs.
