Molecular characterization of Anopheles fluviatilis species complex in the Islamic Republic of Iran

Abstract

A species-specific polymerase chain reaction (PCR) assay was used to identify the species composition of the Anopheles fluviatilis complex in the Islamic Republic of Iran. All the amplified DNA samples from specimens collected from different areas yielded a fragment of 450 bp size, a PCR product corresponding to that of the species denoted as Y. The sequence data from 21 ITS2 [second internal transcribed spacer] regions were compared with those publicly available in the GenBank database and confirmed that the specimens were 100% identical to species Y of India. Species Y is presumably the same as species T that has no role in transmission of malaria in India, whereas An. fluviatilis is known as a secondary vector of malaria in the Islamic Republic of Iran.
