Abstract

Bursa Fabricius (BF), the primary lymphoid organ of poultry, is responsible for humoral immunity. Inpoultry, it is very important for BF to complete its embryonic development and reach to a certainmaturity in terms of maintaining a healthy life of the animal. In this study, BF development and itsmorphometric measurements were investigated in chick embryos. BF was taken from 24 Babcockwhite Leghorn chick embryos on the 10th, 13th, 16th and 21st days of incubation. The average BFweight was 0.006±0.001 g on the 10th day, while this value was 0.037±0.007 g on the 21st day.Average cranio-caudal diameter was different according to the determined incubation days,statistically. While this value was 2.39±0.10 mm on the 10th day, it was 7.55±0.66 mm on the 21stday. The average latero-lateral diameter was ranged from 1.94±0.15 mm to 4.71±0.96 mm, whilethe average dorso-ventral diameter was in the range of 1.48±0.28 mm and 2.29±0.42 mm.Histologically, a central lumen and plica development were observed on the 10th day of incubationin the bursal sections. 13-day-old embryos were found to have epithelial buddings, two differentepithelial structures and three layers of wall in the BF. On the 21st day, we were observed thathistologic development of BF was completed. In conclusion, obtained these data concluded that BFis an important lymphoid organ in terms of maintaining a healthy life of the poultry. It is alsobelieved that the obtained morphometric measurements can be used as reference data for furtherstudies on this organ.

Özet

Kanatlı hayvanların primer lenfoid organı olan Bursa Fabricius (BF) humoral bağışıklıktan sorumludur. Kanatlılarda, BF’nin embriyonik gelişimini tamamlaması ve hayvanın sağlıklı bir yaşamını sürdürmesi açısından belirli bir olgunluğa ulaşması çok önemlidir. Bu çalışmada, civciv embriyolarında BF gelişimi ve morfometrik ölçümleri araştırılmıştır. BF, inkübasyonun 10, 13, 16 ve 21. günlerinde 24 Babcock beyaz Leghorn civciv embriyosundan alındı. Bu çalışmada ortalama BF ağırlığı 10. günde 0.006±0.001 g iken, bu değer 21. günde 0.037±0.007 g idi. Ortalama kraniyokaudal çap belirlenen inkübasyon günlerine göre istatistiksel olarak farklıydı. Bu değer 10. günde 2.39±0.10 mm iken, 21. günde 7.55±0.66 mm idi. Ortalama latero-lateral çap 1.94±0.15 mm ile 4.71±0.96 mm arasında değişirken, ortalama dorso-ventral çap 1.48±0.28 mm ve 2.29±0.42 mm arasındaydı. Histolojik olarak bursal kesitlerde inkübasyonun 10. gününde merkezi bir lümen ve plika gelişimi gözlendi. 13 günlük embriyoların BF’lerinde epitelyal tomurcuklanmalar, iki farklı epitel yapısı ve üç katmanlı duvar tabakasının olduğu bulundu. 21. günde BF’nin histolojik gelişiminin tamamlandığı gözlemlendi. Sonuçta, elde edilen bu veriler BF’nin kümes hayvanlarının sağlıklı yaşamını sürdürmesi açısından önemli bir lenfoid organ olduğu sonucuna varıldı. Ayrıca elde edilen morfometrik ölçümlerin bu organ üzerinde yapılabilecek çalışmalar için referans veriler olarak kullanılabileceği düşünülmektedir.
