Öğe Bacterial and protozoal pathogens found in ticks collected from humans in Corum province of Turkey(Public Library of Science, 2018) Karasartova, Djursun; Güreser, Ayşe Semra; Gökçe, Tuncay; Çelebi, Bekir; Yapar, Derya; Keskin, Adem; Çelik, Selim; Ece, Yasemin; Erenler, Ali Kemal; Usluca, Selma; Mumcuoğlu, Kosta Yani; Taylan Özkan, Hikmet AyşegülBackground: Tick-borne diseases are increasing all over the word, including Turkey. The aim of this study was to determine the bacterial and protozoan vector-borne pathogens in ticks infesting humans in the Corum province of Turkey. Methodology/Principal findings: From March to November 2014 a total of 322 ticks were collected from patients who attended the local hospitals with tick bites. Ticks were screened by real time-PCR and PCR, and obtained amplicons were sequenced. The dedected tick was belonging to the genus Hyalomma, Haemaphysalis, Rhipicephalus, Dermacentor and Ixodes. A total of 17 microorganism species were identified in ticks. The most prevalent Rickettsia spp. were: R. aeschlimannii (19.5%), R. slovaca (4.5%), R. raoultii (2.2%), R. hoogstraalii (1.9%), R. sibirica subsp. mongolitimonae (1.2%), R. monacensis (0.31%), and Rickettsia spp. (1.2%). In addition, the following pathogens were identified: Borrelia afzelii (0.31%), Anaplasma spp. (0.31%), Ehrlichia spp. (0.93%), Babesia microti (0.93%), Babesia ovis (0.31%), Babesia occultans (3.4%), Theileria spp. (1.6%), Hepatozoon felis (0.31%), Hepatozoon canis (0.31%), and Hemolivia mauritanica (2.1%). All samples were negative for Francisella tularensis, Coxiella burnetii, Bartonella spp., Toxoplasma gondii and Leishmania spp. Conclusions/Significance: Ticks in Corum carry a large variety of human and zoonotic pathogens that were detected not only in known vectors, but showed a wider vector diversity. There is an increase in the prevalence of ticks infected with the spotted fever group and lymphangitis-associated rickettsiosis, while Ehrlichia spp. and Anaplasma spp. were reported for the first time from this region. B. microti was detected for the first time in Hyalomma marginatum infesting humans. The detection of B. occultans, B. ovis, Hepatozoon spp., Theileria spp. and Hemolivia mauritanica indicate the importance of these ticks as vectors of pathogens of veterinary importance, therefore patients with a tick infestation should be followed for a variety of pathogens with medical importance. © 2018 Karasartova et al.Öğe Bacterial and protozoan agents found in Hyalomma aegyptium (L., 1758) (Ixodida: Ixodidae) collected from Testudo graeca L., 1758 (Reptilia: Testudines) in Corum Province of Turkey(Elsevier Gmbh, 2020) Arslan Akveran, Gönül; Karasartova, Djursun; Keskin, Adem; Comba, Arzu; Çelebi, Bekir; Mumcuoğlu, Kosta Yani; Taylan Özkan, Hikmet AyşegülHyalomma aegyptium (L., 1758) (Ixodida: Ixodidae) is a hard tick and the main host for adults are Palearctic tortoises of the genus Testudo, while larvae and nymphs are less host-specific and nymphs also attach to humans. In the present study, a total of 261 H. aegyptium ticks were removed from 26 Testudo graeca L., 1758 in Corum Province of Turkey. The most prevalent pathogens identified molecularly in the ticks were Hemolivia mauritanica (51.9 %), followed by Rickettsia aeschlimannii (32.6 %), Ehrlichia spp. (30.2 %), and Bartonella bovis (0.8 %). All samples were negative for Coxiella burnetii, Francisella tularensis, Anaplasma phagocytophilum, Babesia spp., Hepatozoon spp. and Theileria spp. Overall, 97.4 % of the examined adult ticks and 26.3 % of nymphs were infected with at least one pathogen, while 40.9 % of all ticks were infected with only one pathogen, 27.4 % with two pathogens, and 9.9 % with three pathogens, concomitantly. Overall, 80.8 % of the examined blood smears of tortoises were H. mauritanica-positive, and the mean intensity of parasitemia was 4.8 % (1-21). As a conclusion, since the examined tortoises were sampled in gardens and vineyards close to human habitation, and as a rela-tively large percentage of them were infested with ticks carrying pathogenic agents affecting also humans, the importance of tortoises, their ticks and pathogens in terms of the public health should be farther examined.Öğe Çorum ilinde sokak köpeklerini enfeste eden kene türlerinin belirlenmesi(Refik Saydam National Public Health Agency (RSNPHA), 2020) Arslan Akveran, Gönül; Karasartova, Djursun; Comba, Arzu; Comba, Bahat; Keskin, Adem; Taylan Özkan, Hikmet AyşegülObjective: The Province of Çorum is an endemic area for tick-borne diseases such as the Crimean Congo hemorrhagic fever. The aim of this study was to identify the tick species infesting stray dogs found in the surrounding of human habitations. Methods: Hundred stray dogs kept in the Animal Nursing Home of the Veterinary Service of the province were randomly selected during the period of April 2018 and March 2019. Ticks were removed with the help of forceps and placed in 96% ethyl alcohol and stored at +4°C until they were taxonomically identified. Results: The following tick species were found: Ixodes kaiseri, Hyalomma spp., Rhipicephalus sanguineus, Rhipicephalus turanicus and Haemaphysalis parva. The infestation prevalence was 20%, the infestation density 3.3 (1-7) and the abundance was 0.7. The highest numbers of tick were recorded in June and August, while the lowest in April and May. Conclusion: The number of ticks collected from dogs in this study was relatively low, showing that the efforts of the Veterinary Services to control ticks infesting dogs, is successful. This should lower the possibilities of tick-borne diseases and zoonoses which could be transmitted by stray dogs in the region. © 2020. Turk Hijyen ve Deneysel Biyoloji Dergisi. All rights reserved.
