infectious bronchitis virus
Vaccination and infectious bronchitis virus (IBV) challenge in mature laying hens
All pullets currently reared in Australia for egg production are vaccinated with live attenuated strains of infectious bronchitis virus (IBV).However, questions have been raised about possible negative effects of attenuated vaccines in adult layer birds.
Development of real-time PCR test to quantify infections bronchitis virus in tissues of chickens
This study was conducted to develop and evaluate the use of reverse transcriptase real time polymerase chain reaction (RT-PCR) to detect and quantify the viral copy number of infectious bronchitis virus (IBV) from infected tissues of vaccinated and unvaccinated laying hens.
Optimising infectious bronchitis vaccination of laying hens for maximum egg shell quality
This study was designed to evaluate different vaccination protocols for infectious bronchitis virus in laying hens.Age at first vaccination, route of vaccine administration, regular revaccination during lay, and timing of revaccination in relation to an induced moult was investigated.
