In winter 2016/2017, the highly pathogenic avian influenza virus H5N8 was detected in
backyard poultry in Serbia for the first time. The second HPAI outbreak case in backyard poultry
was reported in 2022, caused by subtype H5N1. This is the first study that documents the laboratory
identification and pathology associated with highly pathogenic avian influenza in poultry in Serbia
during the first and second introduction waves. In both cases, the diagnosis was based on real-time
reverse transcriptase PCR. The most common observed lesions included subepicardial hemorrhages,
congestion and hemorrhages in the lungs, and petechial hemorrhages in coelomic and epicardial adipose tissue. Histologically, the observed lesions were mostly nonpurulent encephalitis accompanied
by encephalomalacia, multifocal necrosis in the spleen, pancreas, and kidneys, pulmonary congestion,
and myocardial and pulmonary hemorrhages. In H5N8-infected chickens, immunohistochemical
examination revealed stron...g positive IHC staining in the brain and lungs. Following these outbreaks,
strict control measures were implemented on farms and backyard holdings to prevent the occurrence
and spread of the disease. Extensive surveillance of birds for avian influenza virus did not detect
any additional cases in poultry. These outbreaks highlight the importance of a rapid detection and
response system in order to quickly suppress outbreaks.
