Pathogenicity 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 کاملPathogenicity Study and Restriction Enzyme Profile of a Recently Isolated Infectious Bursal Disease Virus in Iran
The pathogenicity of a recent isolate of Infectious bursal disease virus (IBDV), IR499, isolated from a nonvaccinated flock with 17.5 % mortality rate in susceptible SPF chickens, chickens embryos and broilers was discussed. The molecular characterization of the virus based on the restriction fragment length polymorphism (RFLP) pattern was also investigated. The mortality rates were 85% and 22%...
متن کاملInfectious Bronchitis Virus Variants: Molecular Analysis and Pathogenicity Investigation
Infectious bronchitis virus (IBV) variants constantly emerge and pose economic threats to poultry farms worldwide. Numerous studies on the molecular and pathogenic characterization of IBV variants have been performed between 2007 and 2017, which we have reviewed herein. We noted that viral genetic mutations and recombination events commonly gave rise to distinct IBV genotypes, serotypes and pat...
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 کاملMolecular Studies on Infectious Bronchitis Virus Isolated in Poland
The comparison of the conventional (aimed at the UTR3 fragment) and nested RT-PCR (aimed at the N gene fragment) based methods revealed that nested PCR was about 1000 times more sensitive for the detection of infectious bronchitis virus (IBV). Molecular differentiation of 793/B, D274, and Mass IBV types was also achieved in multiplex nested PCR. Eight from nine studied Polish isolates had the ...
