Full-length Characterization of S1 Gene of Iranian QX Avian Infectious Bronchitis Virus Isolates, 2015
Background and Aims: Avian infectious bronchitis (IB) has prevalent in the most chicken farms during recent years, in spite of the IB vaccination program which has been widely performed in Iran. To better understand the molecular epidemiology of IBV in Iran, the full length sequences of S1 gene of Iranian QX IBVs were determined and phylogenetic analysis was done using some sequences of IBV. M...
متن کاملPathogenicity study of Iranian genotype of avian infectious bronchitis virus (IR-1)
Avian infectious bronchitis (IB) is a major cause of economic losses in poultry industry. The IB virus primarily affects respiratory tract, but various strains differ in their tropism for other target organs such as kidney and alimentary tract. The objective of this study was to estimate the pathogenicity of Iranian IBV variant (IR-1), which is limited exclusively to Iran. Specific pathogen fre...
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 کاملVirulent Avian Infectious Bronchitis Virus, People’s Republic of China
A virulent avian infectious bronchitis virus (IBV) was isolated from 30-day-old broiler chickens that exhibited respiratory symptoms, nephropathologic lesions, and a high proportion of deaths in the People's Republic of China during 2005. The strain, designated YN, was genetically and pathologically characterized. Phylogenetic analysis showed that YN and most of the previously characterized IBV...
