Genetic characterization of Dactylogyroides longicirrus (Tripathi, 1959) Gussev, 1976 by nuclear 28S segment of ribosomal DNA with a morphological redescription.

Abstract

Present communication deals with the redescription of Dactylogyroides longicirrus (Tripathi, 1959) Gussev, 1976 from Puntius sophore at Hastinapur, Meerut U.P., India. The redescription is based on the fresh materials collected by the author. Besides describing detailed morphological features, nuclear ribosomal DNA (rDNA) has also been used to establish the phylogenetic position and genetic diversity of the parasite. Phylogenetic analysis using the neighbor joining (NJ) and maximum parsimony (MP) methods was performed. This study suggests that morphological characters along with molecular identification are essential for validating and identifying species. This is the first published sequence of a species from the genus Dactylogyroides Gussev, 1963.
