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

Review of Infectious Bronchitis Virus Around the World
Avian Diseases, 2012Infectious 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. Different serotypes and genetic types of the virus have been identified worldwide and for the most part do not cross-protect ...

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 ...

Intracloacal infection with avian infectious bronchitis virus
Avian Pathology, 1998An infectious bronchitis virus (IBV) strain HS-91 isolated from kidneys of chicks which died of nephrosis was inoculated via the cloaca of specific pathogen-free (SPF) chicks. These chicks showed more severe clinical signs, grosser kidney lesions and higher mortality than chicks inoculated with the same IBV strain via the trachea.

Pathogenesis of H13 Nephropathogenic Infectious Bronchitis Virus
Avian Diseases, 1990A nephropathogenic Massachusetts strain of infectious bronchitis virus (IBV) designated H13-IBV was isolated from the kidneys of commercial broilers. H13-IBV caused respiratory distress, depression, and diarrhea in specific-pathogen-free chickens. Gross renal lesions included pale coloration, swelling, and urate deposition.

Neutralizing Antibody Complex of Infectious Bronchitis Virus
The Journal of Immunology, 1969Summary The reaction between infectious bronchitis virus-42 (Beaudette) and neutralizing antibody, and dissociation of the antigen-antibody complex, was studied by the plaque technique using chicken embryo kidney cell cultures. Neutralization was a first-order reaction dependent upon time and concentration of antibody.

The replication of infectious bronchitis virus in fowl trachea
Archiv f�r die gesamte Virusforschung, 1972Domestic fowl were exposed to an aerosol of infectious bronchitis virus. Birds were killed at intervals after infection and sections of trachea were examined in the electron microscope. The virus replicated in superficial cells,i.e., ciliated epithelial cells and mucus cells.

PROPAGATION OF INFECTIOUS BRONCHITIS VIRUS IN TISSUE CULTURE
Canadian Journal of Microbiology, 1956Two strains of infectious bronchitis virus were propagated serially in stationary flask cultures of chick embryo tissues. Both strains of virus could be grown in tube cultures of chick embryo tissues. Virus was produced by the cells for approximately one month without any evidence of damage to the cells.

Infectious Bronchitis Virus Genotypes in the Middle East
Avian Diseases, 2021Infectious bronchitis virus (IBV) variability is the result of genetic mutations and/or recombination events followed by selection. Different IBV types have been reported in Middle Eastern countries, of which most relate to different lineages of genotype I based on a phylogenetic analysis of the full-length S1 subunit of the spike gene.

Epidemiology of Infectious Bronchitis Virus
1995Avian infectious bronchitis virus (IBV) is the type species of the genus Coronavirus of the family Coronaviridae. It is of considerable economic importance to the poultry industry worldwide, causing a highly contagious disease affecting the respiratory, reproductive, and renal systems.
