background: the phylogenetic location of chinese spirometra sparganum isolates remains unclear. the aim of this study was to explore the phylogenetic location of the spirometra sparganum isolates from china. methods: the 28s ribosomal dna (rdna) d1 sequences of 14 spirometra sparganum isolates collected from thirteen locations in china were analyzed by using neighbor-joining (nj), maximum parsi...

The present study was performed to compare the mitochondrial genomes between 2 Spirometra tapeworms, Spirometra erinaceieuropaei and Spirometra decipiens (Cestoidea: Diphyllobothriidae), which larval stages are important etiological agents of sparganosis in humans. For each species, the full mitochondrial genome was amplified in 8 overlapping fragments using total genomic DNA purified from a si...

Tapeworms of the genus Spirometra are pseudophyllidean cestodes endemic in Korea. At present, it is unclear which Spirometra species are responsible for causing human infections, and little information is available on the epidemiological profiles of Spirometra species infecting humans in Korea. Between 1979 and 2009, a total of 50 spargana from human patients and 2 adult specimens obtained from...

The genus Spirometra belongs to the family Diphyllobothriidae and order Pseudophyllidea, and includes intestinal parasites of cats and dogs. In this study, a plerocercoid labeled as Spirometra mansonoides from the USA was examined for species identification and phylogenetic analysis using 2 complete mitochondrial genes, cytochrome c oxidase I (cox1) and NADH dehydrogenase subunit 3 (nad3). The ...

Sparganosis, an infection due to the plerocercoid of Spirometra erinacei, are found worldwide but the majority of cases occur in East Asia including Korea. This report is on a recurred case of sparganosis in the subcutaneous tissue of the right lower leg 1 year after a surgical removal of a worm from a similar region. At admission, ultrasonography (USG) of the lesion strongly suggested spargano...

Human sparganosis which was first reported by Patrick Manson in 1882 (Beaver, 1984) is a rare parasitic infection caused by the migrating plero­ cercoid larva or sparganum of a certain group of pseudophyllidean cestodes, namely in the genus Spirometra Mueller, 1937. The adults of these tapeworms are generally found in the intestinal lumen of domestic, feral, or wild canids and felids (Daly, 198...
