Ribonucleoprotein of avian infectious bronchitis virus.
The ribonucleoprotein (RNP) of avian infectious bronchitis virus (IBV) was examined by electron microscopy after shadowing with carbon/platinum. Linear RNP strands up to 6.7 microns in length, from three IVB strains, were sensitive to both pancreatic RNase and to proteases. These strands were obtained from spontaneously disrupted complete particles but not from disrupted incomplete particles th...
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...
متن کاملAvian infectious bronchitis virus.
Infectious bronchitis virus (IBV) is prevalent in all countries with an intensive poultry industry, with the incidence of infection approaching 100% in most locations. Vaccination is only partially successful due to the continual emergence of antigenic variants. At many sites, multiple antigenic types are simultaneously present, requiring the application of multiple vaccines. Although many coun...
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 ...
