Antigenic Characterization of Infectious Bronchitis Virus

The Journal of Immunology, 1968
Summary 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

Duration of Experimental Infectious Bronchitis in Chickens

Research in Veterinary Science, 1968
Summary 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, 1967
CELLS 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 ...
