Batı Karadeniz B ölgesinde yabani küçük memelilerde Bartonella türleri

Bartonella genusundaki türler insanlarda ve hayvanlarda uzun süreli bakteriyemiye neden olan hücre içi bakterilerdir. Bu çalışmada Batı Karadeniz Bölgesi’nde yakalanan Apodemus flavicollis , A. witherbyi, A. uralensis, A. mystacinus , Myodes glareolus, Crocidura suaveolens , Rattus rattus ve Rattus norvegicus türlerinin dahil olduğu 173 küçük memelide, kan kültürü ve moleküler yöntemlerle Bartonella türleri araştırıldı. Bartonella pozitifliği küçük memelilerde kan kültürü ile %63.6 (110/173) bulundu. Kültürde izole edilen Bartonella suşlarının, sitrat sentez gen bölgesi (gltA) DNA dizi analizi ile tür tanımlamaları yapıldı. İzolatlar Bartonella taylorii, B. birtlesii, B. coopersplainsensis ve zoonotik bir tür olan B. grahamii olarak tanımlandı.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 norvegicus 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

INVESTIGATION OF HANTAVIRUS INFECTIONS AMONG CCHFV NEGATIVE CASES IN THE WESTERN BLACK SEA REGION OF TURKEY

Objective: The Hantaviruses and Crimean Congo hemorrhagic fever virus (CCHFV) are members of the Bunyaviridae family. Hantavirus infections causes two main febrile diseases: hemorrhagic fever with renal syndrome (HFRS) and hantavirus cardiopulmonary syndrome (HCPS). Hantaviruses are transmitted by rodents. In 2009, a hantavirus outbreak occurred in the Western Black Sea region of Turkey. For the last 10 years, the prevalence of CCHFV has also been high in this region

Molecular identification of viral agents associated with acute conjunctivitis: a prospective controlled study

Background: Viral conjunctivitis are the most frequent infections in ophthalmology clinics. The diagnosis is usually relying on clinical findings and medical history. However, topical antibiotics are often used unnecessarily addition to symptomatic treatment because of unsure agents. We aimed to detect the Adenovirus, Coxsackievirus and Enterovirus from conjunctiva and pharyngeal samples of patients. Methods: The conjunctiva and pharyngeal samples of the patients with conjunctivitis were taken by Virocult transport media and kept at −80 ̊C up to study day. Adenovirus spp, Enterovirus 70 and Enterovirus 71, Coxsackie A24 and Coxsackie A16 were detected by real-time PCR. Samples from healthy health care workers of ophthalmology clinic were used for control group. Results: A total of 176 samples (conjunctival and pharyngeal samples of 62 patient and 26 healthy subjects) were included. The mean age of 34 (55.7%) male and 27 (44.3%) female patients was 34 ± 17. Twenty five (40.3%) of the patients were receiving antibiotic drops at first visit. The main etiologic agent in conjunctival samples was found to be Adenovirus (46/62, 74.2%) followed by Enterovirus 70 (4/62, 6.4%) and Enterovirus 71 (4/62, 6.4%). Coxsackievirus 16 and 24 were also found in 2 patients (1/62 each, 1.6%). Pharyngeal samples were also positive for Adenovirus (20/62, 32.3%), Enterovirus 70 and 71 (7/62, 11.3% and 5/62, 8.1% respectively), Coxsackievirus 16 and 24 (2/62, 3.2% and 1/61, 1.6%). Conclusions: It is very difficult in viral conjunctivitis to make clinical differentiation caused by different agents because of common clinical signs and symptoms. In routine clinical work, the viral conjunctivitis usually related with Adenovirus. But almost one fourth of the patients’ conjunctivitis were not related to Adenovirus, which shows the importance of the laboratory diagnostics. True diagnosis plays an important role on prevention of contamination and unnecessary use of antibiotics in viral conjunctivitis. Keywords: Adenovirus, Conjunctivitis, Viral, PC
