Infectious bronchitis (IB) is a major threat to the global poultry industry. Despite availability of commercial vaccines, IB epidemic has not been effectively controlled. The exploration novel IBV vaccines may provide new way prevent and control IB. In this study, BLP-S1, bacterium-like particle displaying S1 subunit infectious virus (IBV), was constructed using GEM-PA surface display system. i...

Avian Infectious bronchitis virus belongs to the family Coronaviridae. It is an enveloped virus with large positive stranded RNA genome. In the present study RNA was isolated from viral suspension and transcribed into cDNA. Poultry postmortem cases showing lesions of visceral gout were collected and infectious bronchitis virus were isolated. About 1.2 kb Nucleocapsid gene of virus was amplified...

A multiplex reverse transcription polymerase chain reaction (RT-PCR) was developed and optimized to simultaneously detect 3 subtypes (H5, H7 and H9) of avian influenza virus type A. The developed method was specific to amplify only the HA gene of H5, H7 and H9 of Influenza type A and no amplification with other subtypes of AIV and other avian infectious viruses such as Newcastle disease virus, ...
