Abstract

In this study, naturally infected by Gallid Herpesvirus type-1 in laying hens to be diagnosed by pathological and PCR methods. Sixty pieces of hens were collected in coops from Central Anatolia region. After necropsy, routine pathological processes were applied to the trachea/larynx, sinuses, lungs and air sacs. All organs were also stained by immunoperoxidase method, and PCR methods were applied to formalin fixed paraffin embedded (FFPE) tissues. Immunohistochemically, the positivities were seen in trachea/larynx (78.3%), sinuses (61.6%), lungs (45%) and air sacs (50%). Positive reactions were observed, in mucous and gland epithelia especially located at intracytoplasmic and rarely intranuclear. PCR positivity was observed in the trachea/larynx in 15 (25%) cases, in infraorbital sinus in 11 (18.3%) cases, in lungs in 8 (13.3%) cases and in air sacs in 6 (10%) cases following the tests performed. Following these results, it is easily concluded that histopathology and immunoperoxidase method can usable for diagnosing of the ILT. However, PCR results made by FFPE tissues showed that this method is not adequate to diagnose the ILT alone

Özet

Bu çalışmada Gallid Herpesvirus tip-1 ile doğal enfekte yumurta tavuklarında patolojik yöntemlerle teşhis konularak immunohistokimyasal ve PCR yöntemlerinin teşhiste kullanılabilirliği araştırıldı. Bu amaçla Orta Anadolu'da bulunan bazı illerdeki kümeslerden toplam 60 adet enfekte tavuk toplandı. Yapılan nekropsilerin sonrasında trake, larinks, infraorbital sinus, akciğer ve hava kesesi parçaları alınarak rutin patolojik işlemler uygulandı. Alınan tüm organlar ayrıca indirekt immunperoksidaz yöntemi ile boyandı ve organlara ait formolle fikse edilmiş parafine gömülü (FFPG) dokulara PZR testi yapıldı. İmmunohistokimyasal boyamalar sonucu trake/larinkste %78.3, sinuslarda %61.6, akciğerlerde %45 ve hava keselerinde %50 oranında pozitiflik gözlendi. Pozitif boyanmalar özellikle mukoza ve bez epitellerinde intrasitoplazmik nadiren de intranüklear olarak gözlendi. Aynı zamanda lümene dökülmüş eksudattaki hücre ve sinsityal dev hücrelerinin sitoplazmalarında da boyanmalar tipikti. Yapılan PCR testlerinin ardından trake/larinkste %25, infraorbital sinuslarda %18.3, akciğerlerde %13.3, hava keselerinde %10 oranında pozitiflik gözlendi. Bu sonuçların ardından hastalığın teşhisinde histopatolojik ve immunperoksidaz yönteminin rahatlıkla kullanılabileceği ortaya konmuştur. Ancak, FFPG dokulardan yapılan PCR yönteminin tek başına İLT'yi teşhis etmek için yeterli olmadığı gösterildi
