Nucleotide Sequence Analysis of S1 Gene among Iranian Avian Infectious Bronchitis Viruses Isolated during 2001-2002
Infectious bronchitis (IB) virus genome codes for four structural proteins, among which the S1 subunit of spike glycoprotein comprises the major epitopes to induce neutralizing antibodies. This study involved the comparison of the full S1 sequences of five IB viruses, namely two Massachusetts and three 793/B serotypes, isolated from IB outbreaks during 2001-2002, with all other Iranian an...
متن کاملSequence and Phylogenetic Analysis of Membrane (M) Gene of Infectious Bronchitis Viruses Isolated in Iran during 2014 - 2015
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...
متن کاملSequence analysis of the S1 glycoprotein gene of infectious bronchitis viruses: identification of a novel phylogenetic group in Korea
Twelve Korean infectious bronchitis viruses (IBVs) were isolated in the field from chickens suspected of being carriers of infectious bronchitis between 2001 and 2003. The S1 glycoprotein genes of these IBV isolates were amplified by reverse transcriptase-polymerase chain reaction (RTPCR) and analyzed by restriction fragment length polymorphism (RFLP) analysis. These Korean IBV isolates were cl...
متن کاملGenotyping of Infectious bronchitis viruses isolated from broiler chicken farms in Iran during 2015-2016
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...
متن کاملSequences and Phylogenetic Analysis of Envelope (E) Gene of Iranian Infectious Bronchitis Virus Isolates in Iran
Background and Aims: Infectious bronchitis virus (IBV) is the etiological agent of infectious bronchitis (IB), which is an acute and highly contagious disease of the respiratory and sometimes the urogenital tracts of chickens. In Iran, the disease has been identified in chicken flocks with serological and virus isolation methods. Gene 3c (E) encode envelop (small membrane) protein. For envelope...
