Increased expression of Interleukin-6 related to nephritis in chickens challenged with an Avian infectious bronchitis virus variant
(2015-01-01)
A Brazilian field isolate (IBV/Brazil/PR05) of avian infectious bronchitis virus (IBV), associated with development of nephritis in chickens, was previously genotyped as IBV variant after S1 gene sequencing. The aim of ...
Assessment of molecular and genetic evolution, antigenicity and virulence properties during the persistence of the infectious bronchitis virus in broiler breeders
(2017-10-01)
The infectious bronchitis virus (IBV) causes a highly contagious disease [infectious bronchitis (IB)] that results in substantial economic losses to the poultry industry worldwide. We conducted a molecular and phylogenetic ...

Avian Infectious Bronchitis Virus in Brazil: A Highly Complex Virus Meets a Highly Susceptible Host Population
(FACTA-FUNDACIO ARNCO CIENCIA TECNOLOGIA AVICOLAS, 2010)
Infectious bronchitis (IB) is a highly aggressive disease for poultry in terms of symptoms and economic losses, and the control of this disease is difficult if flocks are not protected against type-specific challenges by ...
Evaluation of an indirect ELISA method for the detection of chicken antibodies against infectious bronchitis virus
(1996-01-01)
An indirect ELISA method was developed and applied to detect antibodies against infectious bronchitis virus (IBV). Three hundred serum samples collected from vaccinated and non-vaccinated chickens under field conditions ...
