Abstract

A number of broiler flocks with respiratory disease and high mortality in five broiler farms in Libya were sampled for detection of infectious bronchitis virus (IBV). Twelve IBV strains from these farms were detected by reverse transcription polymerase chain reaction (RT-PCR) and differentiated by nucleotide sequencing of the hypervariable region of the S1 gene. A pair-wise comparison of the sequences showed two distinctive patterns. Those from farms 1, 2, 4 and 5, formed a separate cluster with 94-99% relatedness to the Egyptian IBV strains CK/Eg/BSU-2/2011, CK/Eg/BSU-3/2011 and Eg/1212B. Sequences from the farm 3 formed another cluster with 100% relatedness to Eg/CLEVB-2/IBV/012 and IS/1494/06. This appears to be the first report on the co-circulation of variant IBVs in Eastern part of Libya
