title: Phylogenetic relationships among Linguatula serrata isolates from Iran based on 18S rRNA and mitochondrial cox1 gene sequences.
abstract: The phylogenetic relationships among seven Linguatula serrata (L. serrata) isolates collected from cattle, goats, sheep, dogs and camels in different geographical locations of Iran were investigated using partial 18S ribosomal RNA (rRNA) and partial mitochondrial cytochrome c oxidase subunit 1 (cox1) gene sequences. The nucleotide sequences were analysed in order to determine the phylogenetic relationships between the isolates. Higher sequence diversity and intraspecies variation was observed in the cox1 gene compared to 18S rRNA sequences. Phylogenetic analysis of the cox1 gene placed all L. serrata isolates in a sister clade to L. arctica. The Mantel regression analysis revealed no association between genetic variations and host species or geographical location, perhaps due to the small sample size. However, genetic variations between L. serrata isolates in Iran and those isolated in other parts of the world may exist and could reveal possible evolutionary relationships.
