Title: rDNA-ITS2 based species-diagnostic polymerase chain reaction assay for identification of sibling species of Anopheles fluviatilis in Iran.
Abstract: A species-specific polymerase chain reaction (PCR) assay using primers already designed, based on differences in the nucleotides of the second internal transcribed spacer (ITS2), was used to identify the species composition of the Anopheles fluviatilis complex in Iran. All the amplified DNA samples obtained from specimens collected from different areas using different collection methods yielded to a fragment of 450 bp size, a PCR product corresponding to the species denoted as Y. Some 21 ITS2 region of Iranian specimens were sequenced and compared with the already published sequence data of species Y from India. The sequence data of the Iranian specimens were 100% identical to that of the Indian specimens, and hence confirmed the PCR assay results. Species Y is presumably species T in India, which has no role in the transmission of malaria, whereas mosquitos of An. fluviatilis are known as a secondary vector in Iran. This conflict will remain to be solved by further biological and molecular studies.
