Infectious bronchitis is a disease in chickens caused by avian coronavirus with a single-stranded positive RNA viral genome and belongs to the genus Gammacoronavirus. AI is an acute respiratory disease affecting chickens' reproductive systems, kidneys, digestive tract, and defence systems. This article reports that a 13-month-old Sentul Dust layer chicken was found to have a standing posture disorder. Physical examination showed that the chicken had a "Penguin-like" standing posture, its mouth was always open, and it had dyspnoea. The animals were euthanised for necropsy and post-mortem examination. Necropsy showed pathological findings in the form of airsacculitis, splenomegaly, ovarian regression, enteritis, haemorrhage of the tonsillar cavity, and fluid-filled cysts in the oviducts. Chickens are diagnosed with Infectious Bronchitis based on clinical signs and anatomical pathology findings in the organs.
