Abstract
Sparganosis is a parasitic disease in humans and animals caused by plerocercoid larvae (spargana) of the genus Spirometra. Spirometra erinaceieuropaei is the major causative agent of the disease in Asian countries. However, molecular evidence of the causative parasite species in animals remains lacking. A total of 19 spargana specimens were obtained from frogs, Hoplobatrachus rugulosus, collected from Myanmar and snakes, Ptyas korros, from Lao PDR and Thailand. A partial sequence of mitochondrial cytochrome c oxidase subunit1 gene (cox1) was amplified, sequenced, and the phylogenetic relationship was constructed using maximum likelihood method. Results revealed that the level of nucleotide variations in the partial cox1 sequence (429 bp) among the spargana ranged 0-3.5%, with 15 variable sites. Phylogenetic analysis indicated that all spargana specimens were S. erinaceieuropaei. This is the first report of S. erinaceieuropaei in P. korros, from Lao PDR and Thailand and H. rugulosus from Myanmar. The results emphasize the need for prevention and control of sparganosis in these regions.
