The infectious bronchitis virus (IBV) causes great economic losses to the global poultry industry. This report describes an IBV sample isolated from a broiler farm in the north of Peru and its genetic relationship with other strains of IBV. The authors sequenced part of the S1 coding region including the sequence of the hypervariable regions HVR1 and HVR2. By RT-PCR and phylogenetic analysis, this isolate was classified into the Asia/South America II (Q1-type strain), which has not been previously reported in Peru. This enriches the molecular epidemiology information about IBV and is useful for the control of this disease in Peru and Latin America.
