Genome of infectious bronchitis virus
Journal of Virology, 1977Techniques are described for the growth and rapid purification of the avian coronavirus infectious bronchitis virus (IBV). Purified IBV has a sedimentation coefficient of 320S and a buoyant density of 1.22 g/ml in sucrose-deuterium oxide equilibrium gradients.

Agent, Infection, and Disease. Infectious bronchitis is caused by the avian coronavirus, infectious bronchitis virus (IBV), which is found worldwide. Infections, depending on the strain, may cause an acute upper‐respiratory tract disease, drops in egg production, decreased egg quality, and nephritis.

Antigenic Characterization of Infectious Bronchitis Virus
The Journal of Immunology, 1968Summary Three antigenically distinct soluble antigens (1–3) are associated with infectious bronchitis virus. The antigens are smaller than the virion. Antigens 1 and 3 are destroyed at 100°C, whereas antigen 2 is not. Antigen 2 is a ribonucleoprotein. The virus is sensitive to ether and sodium deoxycholate. Antigens released by treatment

The structure of infectious bronchitis virus
Virology, 1964Abstract The structure of infectious bronchitis virus of chickens has been examined by the negative staining technique in the electron microscope. The particles are between 800 and 1200 A in diameter and bear projections on their surfaces. The effects of ether, sodium dodecyl sulphate, trypsin, and neuraminidase on the morphology and on certain ...

Infectious bronchitis in New Zealand chickens
New Zealand Veterinary Journal, 1972Abstract Extract Infectious bronchitis is an acute and highly contagious viral disease which typically appears as an upper respiratory tract infection of young chickens (Hofstad, 1959b). The causative agent also causes a drop in the quantity and quality of eggs laid by adult birds (McDougall, 1968) and severe nephritis, commonly termed “uraemia”, in ...

Potential for Polyvalent Infectious Bronchitis Vaccines
American Journal of Veterinary Research, 1975SUMMARY Numerous antigenic types and subtypes of infectious bronchitis virus (ibv) have been isolated and characterized from field epornitics of infectious bronchitis (ib). Thus obvious failures in obtaining the necessary protection from vaccination have been documented and they underscore the urgent need for vaccines which stimulate a broader spectrum

Avian infectious bronchitis virus.
Revue scientifique et technique (International Office of Epizootics), 2001Infectious bronchitis virus (IBV) is prevalent in all countries with an intensive poultry industry, with the incidence of infection approaching 100% in most locations. Vaccination is only partially successful due to the continual emergence of antigenic variants.

The Early History of Infectious Bronchitis
Avian Diseases, 1998Two years later, Bushnell and Brandly (3) reported on an essentially identical disease. They established that the causative agent was a filterable virus because the disease could be transmitted by Berkefeld-filtered material. Because the symptoms of respiratory distress were caused by a filterable virus, Bushnell and Brandly regarded the disease as a ...

Intracellular Development of Infectious Bronchitis Virus
Nature, 1967CELLS infected with infectious bronchitis (IB) virus in tissue cultures of chick or chick embryo kidney have been described as showing shrinkage, vacuolation and detachment from the monolayer1–4. When the immuno-fluorescent technique was used, the growth of IB virus in chick embryo kidney cells, first in the nucleus and later in the cytoplasma, was ...
