Infectious bronchitis (IBV) is an economically important acute, highly contagious disease affecting poultry worldwide. The primary place of IBV replication is the upper respiratory tract from where infection can spread to reproductive organs causing a decrease in egg production and the occurrence of misshapen eggs, changes in shells, and watery albumen leading to lowquality eggs. In our study, samples were submitted to determine causative agents that resulted in respiratory signs of hens and altered egg quality. The hen carcass was inspected by gross pathology and histopathology. Based on pathological findings, tissue samples of the trachea, kidney, ovary, and tracheal and cloacal swabs were tested by rtRT-PCR using two sets of primers. Histopathology findings and the first set of primers confirmed the presence of coronavirus in the tracheal tissue sample. This sample was further tested with an IBV-specific set of primers which undoubtedly confirmed the presence of IBV RNA. Although IBV vaccination in our country is common practice, this study shows that despite vaccines it can come to breach of IBV infection that could cause substantial economic losses. Eggs are considered one of the primal sources of protein, and shells as the primal barrier against microorganisms, must not have any defects to secure eggs' quality and safety. IBV infection does not represent a risk to public health, but its occurrence in production may result in low egg quality and difficulties in the placement of the product on the market.
