Abstract

Q fever is one of the important zoonotic infections which is seen in many parts of the world. Because the isolation of the agent is difficult and time consuming as well as the isolation and identification of the agent requires to be done under biosafety level-3 (BSL-3) conditions, the diagnosis of the disease is largely based on molecular and serological techniques. The aim of this study was to detect Coxiella burnetii accurately and quickly for routine diagnosis of the disease from the clinical samples by using real time PCR and to detect the presence of the C. burnetii in Şanlıurfa District. A total of 202 abortus materials kept at -80°C and previously brought to Harran University Faculty of Veterinary Medicine Department of Microbiology for diagnosis and 25 aborted materials brought to our lab during this study period were tested by Real-Time PCR. For Real-Time PCR analysis, a commercial C. burnetii Real-Time PCR kit was used including positive controls. Besides, a classical PCR was performed by using a pair of primers which amplifies a 74-bp fragment of the com 1 gene of C. burnetii, which is highly conserved region in the genom of agent and amplicons were visualized in the 4% agarose gel. Four out of 227 test samples (1.8%) samples were found positive by both Real-Time and classical PCR test. In the end of the study, it was concluded that this important zoonotic agent could be determined fast and reliable and contribute to take necessary preventive measures on time.

Özet

Q fever dünyanın birçok ülkesinde görülen önemli zoonotik infeksiyonlardan biridir. Etkenin kültürünün zor ve uzun zaman alıcı olmasının yanında Biyogüvenlik seviyesi-3 (Biosafety level-3) BSL-3 koşullarında gerçekleştirilmesi gerekliliği, hastalığın teşhisinin geniş oranda moleküler ve serolojik olmasını sağlamıştır. Bu çalışmada, ruminantlarda abortusa neden olan bu önemli patojenin rutin teşhiste Real-Time PCR ile hızlı ve doğru bir şekilde saptanması ve Şanlıurfa yöresinde hastalığın varlığının belirlenmesi amaçlandı. Çalışmada Harran Üniversitesi Veteriner Fakültesi Mikrobiyoloji Anabilim Dalına teşhis amaçlı getirilmiş olan ve -80 ºC’de saklanan toplam 202 adet sığır, keçi ve koyun atık materyali ve çalışma döneminde gelen 25 atık materyali Real-Time PCR tekniği ile incelendi. Bu amaçla içinde pozitif kontrol içeren Coxiella burnetii Real-Time PCR kiti kullanıldı. Ayrıca test edilen C. burnetii suşları arasında son derece korumalı bir bölge olan C. burnetii com 1 geninin74-bp lik bir fragmentini amplifiye eden primer çiftleri kullanılarak klasik PCR yapıldı ve elde edilen amplikonlar agaroz jelde görüntülendi. Çalışmada incelenen toplam 227 adet atık materyalinden 4 adedi (%1,8) hem Real-Time PCR hem de klasik PCR ile pozitif bulundu. Çalışmanın sonucunda önemli bir zoonoz olan bu ajanın hızlı ve güvenli bir şekilde tespit edilebildiği ve gerekli kontrol önlemlerinin alınmasına katkıda bulunacağı kanaatine varıldı.
