Abstract

A male patient with taeniasis was admitted Tarim University hospital in June 2020. The patient complained that there were milky white peristaltic worm fragments in the feces and the patient reported a history of taeniasis. After administration of areca nuts and pumpkin seeds, one milky tapeworm was expelled. Morphological observation of the expelled worm was carried out under stereo microscope. Combined with epidemiological data and patient’s dietary habits, the sample was preliminarily identified as Taenia saginata infection. The gene amplification results based on the nad1 and rrnS loci of the tapeworm mitochondrion showed that fragments of 529 bp and 357 bp were successfully amplified by PCR. BLAST analysis showed that the gene sequences of the nad1 and rrnS loci had 100% and 99.7% homology to T. saginata collected from human in Kenya (GenBank access number AM503345) and Japan (GenBank access number AB031355). Therefore this tapeworm was identified as T. saginata. The patients were followed up after 3 and 6 months, respectively. The patients were in good health and no tapeworm was expelled.
