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

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

Duration of Experimental Infectious Bronchitis in Chickens
Research in Veterinary Science, 1968Summary Chickens with infections bronchitis (IB) were shown to harbour the virus Jor up to 49 clays after inoculation when housed in strict isolation, but for over 4 months when isolation was less effective. Virus was detected, in the latter circumstances, in spite of a significant level of circulating antibody in the infected chickens; it was ...

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 ...
