    (ANKARA UNIV PRESS, 2015) Celebi, Bekir; Karagoz, Alper; Oktem, Mehmet Ali; Carhan, Ahmet; Matur, Ferhat; Ozkazanc, Nuri Kaan; Durmaz, Riza
    The species within the genus Bartonella are intracellular bacteria causing long-lasting bacteremia in humans and animals. In this study, Bartonella spp. in 173 small mammals, which were Apodemus flavicollis, A. witherbyi, A. uralensis, A. mystacinus, Myodes glareolus, Crocidura suaveolens, Rattus rattus and Rattus norvegims species captured from Western Black Sea Region of Turkey, were investigated by blood culture and molecular methods. The positivity of Bartonella was 63.6% (110/173) by blood culture of small mammalian. The gltA gene regions for the isolated strains were identified by DNA sequencing analysis. Isolates were identified as Bartonella taylorii, B. birtlesii, B. coopersplainsensis and a zoonotic B. grahamii.

    Borrelia miyamotoi in wild rodents from four different regions of Turkey
    (Elsevier Gmbh, 2023) Celebi, Bekir; Yeni, Derya Karatas; Yilmaz, Yusuf; Matur, Ferhat; Babur, Cahit; Oktem, Mehmet Ali; Sozen, Mustafa
    Borrelia miyamotoi is a tick-borne zoonotic agent that causes hard tick-borne relapsing fever, an emerging disease in humans. Some small mammalian and bird species are reported to be reservoirs of B. miyamotoi. This study aims to examine Borrelia species present in rodents captured from rural areas of Turkey. Blood samples of rodents were initially screened with Borrelia 16S rRNA qPCR. The Borrelia flaB gene was subsequently amplified by conventional PCR, after which all positive samples were sequenced. Borrelia miyamotoi was observed in nine out of 536 blood samples (1.7%) collected from wild rodents. Phylogenetic analysis showed that all positive samples belonged to the European genotype clade of B. miyamotoi. PCR positivity was 5.3%, 3.7%, and 1.8% in Apodemus uralensis, Apodemus flavicollis, and Myodes glareolus, respectively. Borrelia burgdorferi sensu lato that causes Lyme borreliosis in humans could not be detected in the rodents. In this study, presence of B. miyamotoi DNA is reported for the first time in rodents in Turkey.

    Characterization of Bartonella taylorii Strains in Small Mammals of the Turkish Thrace
    (Springer, 2020) Polat, Ceylan; Celebi, Bekir; Irmak, Sercan; Karatas, Ahmet; Colak, Faruk; Matur, Ferhat; Sozen, Mustafa
    Rodents play role as a reservoir for some Bartonella species which cause different clinical manifestations in humans. Bartonella spp. existence in rodents of Turkish Thrace has been detected for the first time, and the risky habitat types were evaluated for the infection. Ninety individuals belonging to three small rodent species were screened by PCR, and the overall prevalence of Bartonella infection was 22.2%. The strains were characterized molecularly based on the phylogenetic analyses of two housekeeping genes, rpoB and gltA. They clustered with B. taylorii. The significant effects of habitat types and rodent species on Bartonella infections were observed. It was detected that B. taylorii prevalence was the highest in the swamp forest habitat and A. flavicollis species. The present study demonstrates that A. flavicollis is the reservoir of B. taylorii in the European part of Turkey.

    Molecular Survey of Babesia microti (Aconoidasida: Piroplasmida) in Wild Rodents in Turkey
    (Oxford Univ Press Inc, 2019) Usluca, Selma; Celebi, Bekir; Karasartova, Djursun; Gureser, A. Semra; Matur, Ferhat; Oktem, M. Ali; Sozen, Mustafa
    Babesia microti (Aconoidasida: Piroplasmida) (Franca, 1910) is an important tick-borne zoonotic parasite with rodents serving as reservoir hosts. In the present study, 536 rodents were captured from Burdur, Bartin, Giresun, and Yozgat provinces of Turkey between the years 2010 and 2012, and blood samples were examined for the presence of Babesia spp. using conventional PCR which targeted the 18S rRNA gene. The sequence analysis of PCR amplicons was tested for B. microti as well as for Hepatozoon spp., and Sarcocystis spp. Overall, 5.8% of the rodents were positive for B. microti: 41% in Myodes glareolus, 7.7% in Chionomys roberti, and 2% in Apodemus spp., whereas no Babesia DNA was detected in Mus macedonicus and Microtus spp. Six rodents were positive for Hepatozoon spp. and one rodent was positive for Sarcocystis spp. Overall, 14.9 and 4.5% of rodents captured from Bartin and Giresun provinces, respectively, were PCR positive for B. microti, whereas none of rodents captured in Burdur and Yozgat were positive for Babesia spp. The sequence data of B. microti from rodents revealed that all sequences belonged to the zoonotic genotype. Sequences of B. microti obtained from rodents of the Bartin province were genotypically closer to European isolates, whereas those obtained from rodents of the Giresun province were closer to Russian and Mongolian isolates.

    Seroprevalence of Coxiella burnetii in Stray Cats in Central Anatolia
    (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2008) Kilic, Selcuk; Komiya, Tomoyoshi; Celebi, Bekir; Aydin, Nejat; Saito, Junko; Toriniwa, Hiroko; Babuer, Cahit
    Coxiella burnetii causes Q fever (Coxiellosis) in humans and animals worldwide. The present study was carried out to determine the seroprevalence of Q fever among stray cats in 3 providences (Ankara, Nigde, and Kayseri) in Central Anatolia, Turkey. A total of 143 sera from stray cats were examined for the presence of IgG against C. burnetii phase II antigen by indirect fluorescent antibody test (IFAT). Seven out of the 143 (4.9%) stray cats were seropositive for Q fever, with titers of 1:64 to 1:256. Seroprevalences in Ankara, Nigde, and Kayseri provinces were 1.6%, 7.4%, and 8.3%, respectively. This is the first report of the presence of C. burnetii in cats in Turkey.
