Successive occurrence of recombinant infectious bronchitis virus strains in restricted area of Middle East
Routine molecular diagnostic testing by our laboratory, based on using a primer pair with conservative binding sites on the spike glycoprotein coding sequence, has indicated the recurring of a unique phylogenetic cluster of chicken infectious bronchitis viruses (IBV) in the Middle East since 2010. The nearly full-length S1 subunit of the spike gene phylogeny of selected strains, however, split ...
متن کاملPresence of Infectious Bronchitis Virus Strain CK/CH/LDL/97I in the Middle East
Infectious bronchitis virus (IBV) is a very dynamic and evolving virus, causing major economic losses to the global poultry industry. In early 2011, respiratory disease outbreaks were investigated in Iraq, Jordan, and Saudi Arabia. Five IBV isolates (JOA2, JOA4, Saudi-1, Saudi-2, and Iraqi IBV) were detected by diagnostic-nested nucleocapsid RT-PCR. Strain identification was characterised by se...
متن کاملGenotyping of avian infectious bronchitis virus in Afghanistan (2016-2017): the first report
Background: Avian infectious bronchitis (IB) is a highly contagious viral disease which affects the poultry industry. The virus exists in a wide variety of genotypes, and phylogenetic analysis has been used to classify infectious bronchitis virus (IBV) strains. Aims: The object of the study is a molecular characterization of circulating IBV in Afghanistan as a ...
متن کاملThe emergence of Q1 genotype of avian infectious bronchitis virus in Iran, 2019: the first report
Background: Avian infectious bronchitis (IB) is an infectious viral disease of chickens. The effective protection of chickens against many different infectious bronchitis virus (IBV) variants is not achieved unless the circulating genotypes in the region are identified and the cross-protection of the potential of vaccines in use is assessed. Aims:In a monitoring program of IBVs, a new genotype ...
متن کاملEmergence of variant avian infectious bronchitis virus in India
Background: Infectious bronchitis virus (IBV) is the etiological agent of an acute and highly contagious disease. Infectious bronchitis (IB) affects chicken of all ages and poses major economic loses to the poultry industry worldwide. The continuous evolution of the spike protein (S1) of IBV is responsible for the prevalence of many serotypes/genotypes around the world. Multipl...
