Infectious bronchitis virus (IBV) is currently classified within the species Avian coronavirus, genus Gammacoronavirus, family Coronaviridae, order Nidovirales. IBV is an enveloped virus with a single-stranded positive-sense RNA genome of approximatively 27 kb, which displays the following gene organization: 5′UTR-1a/1ab-S-3a-3b-E-M-5a-5b-N-3′UTR.

Infectious bronchitis virus (IBV) is a gamma coronavirus that causes a highly contagious disease in chickens. The virus can affect the upper respiratory tract and the reproductive tract, and some strains can cause a nephritis.

Infectious bronchitis virus (IBV) is a highly contagious avian Gammacoronavirus that affects mainly chickens (Gallus gallus) but can circulate in other avian species. IBV constitutes a significant threat to the poultry industry, causing reduced egg yield, growth and mortality levels that can vary in impact.

Infectious bronchitis virus (IBV) is ubiquitous in most parts of the world where poultry are reared and is able to spread very rapidly in non-protected birds. It is shed via both the respiratory tract and the faeces, and can persist in the birds and the intestinal tract for several weeks or months.

2023年11月29日 · The avian coronavirus, infectious bronchitis virus (IBV), is a rapidly evolving virus due to the high frequency of mutations and recombination events that are common in coronaviruses. This leads to the continual emergence of novel genotypes that show variable or poor crossprotection.

2020年6月22日 · The history of infectious bronchitis virus (IBV) fits well with the above-mentioned scenario. Despite being known since the 1930s, it still represents one of the main causes of disease and economic losses for the poultry industry.

Infectious bronchitis virus (IBV) is currently classified within the species Avian coronavirus, genus Gammacoronavirus, family Coronaviridae, order Nidovirales.

Many different serotypes or genotypes of Infectious Bronchitis Virus are recognized. In general, different serotypes of the virus do not cross‐protect. However, some strains of the virus are quite effective at inducing cross protection against other serotypes and are referred to as protectotypes.
