DNA analysis has recently become possible which overcomes the problems of differentiating human taeniid cestodes morphologically. In the present study, we evaluated PCR coupled to restriction fragment length polymorphism to differentiate Taenia solium from Taenia saginata eggs present in fecal samples from naturally infected patients. A different Dral-RFLP pattern: a two-band pattern (421 and 100 bp) for T saginata and a three-band pattern (234, 188, and 99 bp) for T solium was observed allowing the two species to be separated.. The lower detection limit of the PCR-RFLP using a non-infected fecal sample prepared with a given number of T saginata eggs was 34 eggs in 2 g stool sediment. The 521 bp mtDNA fragment was detected in 8 out of 12 Taenia sp. carriers (66.6%). of these, three showed a T solium pattern and five a T saginata pattern. (c) 2005 Elsevier B.V.
