Genetic evidence for conspecificity between Dermacentor marginatus and Dermacentor niveus.

摘要: Ticks are hematophagous arthropods transmitting several harmful human and animal pathogens like viruses, Rickettsia, bacteria, protozoa. The identification speciation of ticks were normally performed in Iran using key Arthur (1960) Kaiser Hoogstraal (J Parasitol 49:130–139, 1963) or on the basis morphological characteristic keys recommended by Walker et al. (2003). Although these well prepared, but there some cases due to strong overlapping characteristics between species Dermacentor marginatus niveus accompanied with serious problems. D. have been intermittently used synonymously is no a generally agreement specification species. To find out more about two species, we analyzed complete nucleotide sequence ITS-2 region. Interestingly, found indeed homology 99% region niveus. Since has 98% other GenBank registered marginatus, both examined showed minimal differences, therefore believe that could belong same 1% differences can be understand as an intra-species polymorphism. rRNA gene from under accession no.
