Abstract

Abstrak Tujuan dari penelitian ini untuk melaporkan kasus penyakit infeksi saluran pernafasan yang disebabkan oleh bakteri Ornithobacterium rhinotracheale. Pengamatan meliputi patologi anatomi dan hasil isolasi identifikasi bakteri. Unggas dilakukan nekropsi, diamati perubahan pada organ, sampel trachea diambil secara aseptis kemudian dilakukan isolasi pada media Blood Agar, Chocholate Agar, MCA, pemeriksaan mikroskopis dan uji biokimia antara lain TSIA, SIM, SCA, Katalase, Urease, MR. Hasil pemeriksaan menunjukkan keberadaan bakteri Ornithobacterium rhinotracheale, pemeriksaan makroskopis menunjukkan koloni yang kecil, berwarna keabuan. Pemeriksaan mikroskopis, bakteri berbentuk batang pleomorfik gram negatif. Bakteri tidak tumbuh pada MCA, tidak ada perubahan pada media TSIA, Bakteri non motil, hasil uji indol, SCA, MR dan urease negatif. Kempat jenis unggas menunjukkan perubahan patologi antara lain hemorragi pada trachea dan paru-paru, namun air sac normal dan tidak menunjukkan adanya lesi spesifik, hanya sampel bebek dengan kode I-11 yang terjadi perubahan pada air sac. Berdasarkan hasil isolasi dan identifikasi bakteri dapat disimpulkan keberadaan bakteri Ornithobacterium rhinotracheale dari beberapa jenis unggas yang berbeda antara lain, ayam layer, ayam broiler, ayam hias lokal dan bebek. Kata kunci: Ornithobacterium rhinotracheale, unggas, penyakit saluran pernafasan Abstract The aim of this study was to report cases of respiratory tract infection caused by the bacterium Ornithobacterium rhinotracheale. Observations included anatomical pathology and bacterial isolation results. Poultry was necropsed, observed changes in organs, trachea samples were taken aseptically then isolated on Blood Agar, Chocholate Agar, MCA, microscopic examination and biochemical tests, including TSIA, SIM, SCA, Catalase, Urease, MR. The results of the examination showed the presence of Ornithobacterium rhinotracheale bacteria, macroscopic examination showed small, grayish colored colonies. Microscopic examination, gram-negative pleomorphic rod-shaped bacteria. Bacteria did not grow on MCA, there was no change in TSIA media, non-motile bacteria, the results of the indole test, SCA, MR and urease were negative. All four types of birds showed pathological changes, including hemorrhage in the trachea and lungs, but the air sacs were normal and did not show any specific lesions, only duck samples with code I-11 had changes in the air sacs. Based on the results of isolation and bacteria, it can detect the presence of Ornithobacterium rhinotracheale from several different types of poultry, including layer chickens, broilers, local ornamental chickens and ducks. Keywords: Ornithobacterium rhinotracheale, poultry, respiratory disease
