Emergence 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 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...
متن کاملpH stability studies with avian infectious bronchitis virus (coronavirus) strains.
A comparison of 17 infectious bronchitis virus strains, using the same test procedure and assay system, demonstrated that stability at an acid pH is a variable characteristic of the avian coronaviruses.
متن کاملphylogenetic analysis comparing partial s1 gene of avian infectious bronchitis virus to commercial vaccine strains in iran
background: infectious bronchitis is a highly contagious disease which may cause poor weight gain and low feed efficiency in infected chickens. there are a large number of reported serotypes/genotypes, which makes the control of the disease more difficult through vaccination. however, there are only a few amino acid differences in the s1 protein of vaccine and wild type strains which are respon...
