Molecular identification and phylogenetic analysis of human parasitic Taenia sp samples isolated in Vietnam

ABSTRACT

A portion of 652bp of mitochondrial-encoded cob gene was amplified by polymerase chain reaction (PCR) from different Taenia sp samples (tspVN1-10) of different forms of adult, cysticercus isolated in Vietnam. The nucleotide and amino acid sequences of Vietnamese Taenia sp samples were comparatively aligned with the known corresponding sequences of other Taenia species in GenBank. Results showed that TspVN1-3 is Taenia asiatica, TspVn4-6 is Taenia saginata, and TspVN7-10 is Taenia solium. The Vietnamese T.solium is clustered with the Asian T.solium species, while the Vietnamese T.asiatica is clustered with Taiwanese and T.saginata together with the Chinese T.saginata isolate
