Abstract

Amaç: Bu çalışma, Bangladeş Nilphamari’de infeksiyöz bursal hastalığı (IBD)’nın sebep olduğu prevalans, mortalite, morbidite ve makroskopik patolojik değişikliklerin oranını belirlemek amacıyla yapıldı. Gereç ve Yöntem: Nilphamari Bölgesinde IBD yönünden şüpheli 50 broyler çiftliği belirlendi. Çalışma 9 Mayıs - 17 Haziran 2010 tarihleri arasında yapıldı. Çalışmada rastlanan en önemli patolojik lezyonlar; bacak ve göğüs kaslarında kanamalar, böbreklerde şişkinlik, Bursa fabriciinin yangılı, ödematöz, hiperemik, kanamalı ve atrofik durumları idi. Bulgular: Toplam prevalans, mortalite ve morbidite oranları sırası ile %8.42, %6.38 ve %1.37 olarak belirlendi. Dört haftalık broylerlerin IBD’ye oldukça (%44) duyarlı oldukları, 3 (%26) ve 5 (%24) haftalıkların ise daha az duyarlılık gösterdikleri tespit edildi. Yaşları iki haftaya kadar olanlarda klinik IBD’ye yönelik hiç bir bulguya rastlanmadı. Öneri: Bu çalışmanın, IBD’nin Bangladeş’te Nilphamari Bölgesindeki mevcudiyetine ve seyrine araştırmacıların dikkatini çekeceği ve hastalığın bölgedeki formuna ışık tutacağı
düşünülmektedir.

Status of infectious bursal disease in broilers

Abstract

Aim: The present study was conducted to determine prevalence, mortality, morbidity and pathological changes of infectious bursal disease (IBD) in broilers in Nilphamari district of Bangladesh.Materials and Methods: Fifty broiler farms of Nilphamari district were suspected for IBD. Study was carried out during the period of May 9 to June 17, 2010. The major macroscopic pathological lesions observed in this study were hemorrhages on thigh and breast muscles, kidneys were found swollen and principal lesions were in the bursa of Fabricious which appeared inflamed, edematous, hyperemic and finally hemorrhagic and atrophied. Results: Total prevalence, mortality and morbidity rates were 8.42, 6.38% and 1.37%, respectively. Four weeks old broilers were highly susceptible to IBD (44%) followed by 3rd week (26%) and 5th week (24%) and no clinical case was found positive for IBD in first two weeks of age. Conclusion: This study will stimulate our interest and throw new light on the level of disease episodes prevailing at present in the Nilphamari district of Bangladesh.
