First Record of Ixodes arboricola (Ixodida: Ixodidae) from Turkey with Presence of Candidatus Rickettsia vini (Rickettsiales: Rickettsiaceae)

Abstract

Birds are the specific hosts of many tick species and may contribute to the dissemination of ticks and tick-borne pathogens throughout the world. Determination of ticks infesting birds and their pathogens are important for the detection of natural foci of human pathogens. Unfortunately, there is very limited information about the occurrence of ticks on birds and associated pathogens in Turkey. We performed a tick survey on three passerine bird species; Parus major, Sylvia atricapilla, and Turdus merula. Ticks collected from these birds were identified to species and tested for the presence of Borrelia, Ehrlichia, and Rickettsia species. Ixodes arboricola Schulze & Schlottke, Ixodes frontalis Panzer, and Ixodes ricinus L. were found on the birds. This is the first study reporting the presence of I. frontalis and I. arboricola on S. atricapilla and P. major, respectively, in Turkey. In addition, the results of polymerase chain reaction (PCR) with primers specific for gltA and ompA genes and DNA sequence analysis of positive PCR products indicated the presence of Candidatus Rickettsia vini in I. arboricola ticks. In conclusion, this is the first record of both I. arboricola and Candidatus Rickettsia vini in Turkey. Therefore, future studies needed to be conducted on the ticks infesting birds and their pathogens to elucidate the role of birds in the dispersal of tick species and tick-borne pathogens in Turkey. © 2014 Entomological Society of America.
