Abstract

Background: A combined morphological and molecular survey was performed to determine the agent of human linear dermatitis Paederus Fabricius, 1775 (Coleoptera: Staphylinidae, Paederinae) species composition in Mazandaran Province in the Caspian Sea coast in northern Iran, where most of linear dermatitis cases of the country occurred. Methods: Altogether, 397 Paederus specimens were collected from May to August 2021 and classified using morphological characters and ITS2-rDNA sequence analysis. Results: Morphological investigation revealed that all the specimens were Paederus fuscipes. ITS2 polymerase chain reaction (PCR) direct-sequences and the profiles of restriction fragment length polymorphism (RFLP) derived from digestion of PCR products by HinfI, HpaII, and SalI enzymes were identical confirming the morphological results, implying that all specimens belonged to a single taxon. Conclusion: Paederus fuscipes (Fabricius, 1775) is considered the dominant taxon and responsible for linear dermatitis in Mazandaran Province. To our knowledge, we have provided the first molecular typing of Paederus beetles at the species level, suggesting that ITS2-rDNA characterization is an alternative tool for species discrimination of Paederus spp. Copyright © 2023 The Authors.
