BACKGROUND: Avian infectious bronchitis is considered as an important viral disease worldwide. Genotyping based on the S1 subunit of spike protein gene of the causative agent, avian infectious bronchitis virus, can be used to classify IBV isolates. Objective: This survey was carried out to characterize the infectious bronchitis virus (IBV) genotypes circulating in Iran and determine their preva...
Background and Aims: Avian infectious bronchitis virus (IBV) has a worldwide distribution and mutations occurring in the large viral genome of IBV have led to extensive antigenic variations among IBVs. This is the first study conducted to determine the complete membrane (M) gene sequences of different Iranian IBV genotypes. Materials and Methods: The M gene of three 793/B (IBKG1,6,7), one Mass...
