Molecular detection and prevalence of chlamydophila psittaci in the blood, liver and muscle tissue of Urban pigeons (Columba livia domestica) in Iran
Chlamydophila psittaci (C. psittaci) güvercinlerde yaygın olarak bulunan patojen bir bakteridir. Bu hayvanlar çoğunlukla klinik belirti göstermeksizin enfektedirler. Güvercinler muhtemelen en çok Klamidya ile enfekte olan kanatlı türleridir. Enfekte kuşlardan Klamidyaların yayılımı sıklıkla rapor edilmiştir. Bu çalışma ile konvensiyonel polimeraz zincir reaksiyonu kullanılarak İranda şehir güvercinlerinin kan, karaciğer ve kas dokularında C. psittacinin belirlenerek prevalansının ortaya konulması amaçlanmaktadır. Çalışmada İranda değişik satış yerlerinden elde edilen 90 güvercin kullanıldı. Klinik belirtilere dayanarak klamidiyozis şüpheli olan bu güvercinlerin 26sı dişi ve 64ü erkekti. Her hayvanın kan, karaciğer ve kas dokularını içeren toplam 270 örnek hayvanlardan elde edildi. C. psittaci 16 (%17.78) kan örneğinde, 14 (%15.56) karaciğer örneğinde ve 5 (%5.56) kas dokusunda tespit edildi. Bu çalışma güvercinlerin C. psittaci için taşıyıcı olarak görev yaptığı bilgisini desteklemektedir. Bu nedenle sürekli takip ve kontrolün yapılması Klamidya ile enfekte güvercinlerin yaygınlığı ve buna ilişkin risklerin anlaşılması için uzun süreli devam ettirilmelidir. Böyle bir uygulama aynı zamanda insanlara enfeksiyonun yayılmasını kontrol altına almada da yararlı olacaktır.
İranda Şehir Güvercinlerinde (Columba livia domestica) kan, karaciğer ve kas dokularında chlamydophila psittacinin moleküler metotlarla belirlenmesi ve prevalansı
Chlamydophila psittaci (C. psittaci) is a widespread pathogenic bacterium in pigeons. These animals are mostly infected without any clinical signs. Pigeons are probably the most commonly reported chlamydia-infected avian species. Shedding of Chlamydia from infected birds has been widely reported. This study was conducted to detect and to determine the prevalence of C. psittaci in the blood, liver and muscle tissue of urban pigeons in Iran using conventional polymerase chain reaction. In this study, authors used 90 pigeons from diferent retail shops across Iran. The study was including 26 female and 64 male pigeons with suspected Chlamydiosis based on clinical signs. During examination of the corpses we took 270 samples in total, including blood, liver and muscle tissue from each animal. C. psittaci was detected in 16 (17.78%) blood samples, 14 (15.56%) liver samples and 5 (5.56%) samples of muscle tissue. This study supports the fact that pigeons serve as carriers of C. psittaci. Therefore, continuous surveillance of this bacterium will go along way in understanding the distribution and risks associated with Chlamydia infected pigeons. This will be beneficial in prevention and control risks of infection in humans.
