Jejunal perforation caused by morphologically abnormal Taenia saginata saginata infection.

ABSTRACT

We report a case of jejunal perforation caused by infection with taeniid tapeworm possessing unusual morphology that has not been previously described. Among five cestodes recovered during operation, one exhibited a bifurcation at the posterior end and the other harbored a lateral branching of immature segments from the main strobila. By sequence analysis of the mitochondrial cytochrome c oxidase I gene and the 28S rRNA gene has confirmed them to be Taenia saginata saginata.
