A broiler farm in Jeonbuk province experienced high mortality due to decreased feed intake and poor growth, and pathological evaluation of 11- and 17-day-old broilers was performed, which led to the diagnosis of runting-stunting syndrome. From the start of the rearing period to shipment, 18.4% of the chickens in the three barns experiencing continuous culling and mortality were affected, compared to 7.7% in the other five barns. Gross findings on the 11-day-old broiler chicken revealed proventricular dilatation and hemorrhage, intestinal hemorrhage, urate deposition in the pericardium and renal tubule, nephropathy, and mild hepatic capsulitis. Similar proventricular dilatation and hemorrhage were observed in the 17-day-old broiler chickens. In addition, hepatitis and pericarditis were observed with the progression of secondary bacterial infection, and pathogenic Escherichia coli was isolated from these lesions. As a result of PCR, Newcastle disease virus, fowl adenovirus, chicken anemia virus and Marek’s disease virus were not detected in the all tissue samples. In contrast, infectious bronchitis virus was detected in the proventriculus, kidney and cecal tonsil. chicken astrovirus was detected in the intestine, cecal tonsil and bursa of Fabricius, and chicken parvovirus was detected in proventriculus, intestine, cecal tonsil and bursa of Fabricius. By sharing the diagnostic process of a case of malabsorption syndrome through this case report, we hope that it can be widely utilized in the diagnostic process of livestock disease pathognomonic institutions.
