Analisa Flow Cytometry pada Subpopulasi Sel T-Limfosit Bursa Fabricius Ayam Pedaging Pasca Infeksi Salmonella typhimurium dan Pemberian Pakan Tambahan Polyscias obtusa
Abstract
Tujuan penelitian ini adalah mengetahui adanya aktivitas imunomodulator daun Polyscias obtusa pada organ bursa fabricius ayam pedaging yang terinfeksi bakteri Salmonella typhimurium, serta mengetahui dosis optimum penambahan daun Polyscias obtusa dalam mempengaruhi jumlah subpopulasi T-limfosit pada organ bursa fabricius ayam pedaging yang terinfeksi Salmonella typhimurium. Prosedur kerja yang dilakukan adalah konfirmasi isolat bakteri Salmonella typhimurium, pemberian daun Polyscias obtusa, infeksi bakteri Salmonella typhimurium, pembedahan, isolasi sel, analisis Flow Cytometri, analisis data. Hasil penelitian menunjukkan bahwa Pemberian pakan alami dengan tambahan daun Polyscias obtusa dengan variasi dosis 0,08%, 0,16%, tidak memberikan pengaruh terhadap jumlah relatif CD8+ dan B220+ pada Bursa fabricius. Sehingga, tidak ada perbedaan yang signifikan antara pakan pabrik dan pakan alami dengan tambahan daun Polyscias obtusa.. Namun, pada dosis 0,26 % fase finisher terlihat peningkatan jumlah relatif sel CD4+ yang siginifikan dibandingkan fase starter. Dapat disimpulkan bahwa, dosis 0,26% merupakan dosis optimum dalam meningkatkan proses proliferasi jumlah sel CD4+ sebagai agen imunomodulator pada bursa fabricius ayam pedaging.
