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 ...

Infectious bronchitis virus in Romanian broiler farms
Veterinary Record, 2017 We have been undertaking a specific surveillance programme to study the molecular epidemiology of infectious bronchitis virus (IBV) in Romanian broiler farms. The results of our monitoring activity, which detected and characterised Romanian variant 2 (GI-23) strains, corroborate the rising evidence of variant 2 genotype spreading westward through ...

Infectious Bronchitis Virus in Testicles and Venereal Transmission
Avian Diseases, 2011Even though males represent only 8%-12% of the birds of a breeder flock, their role in infectious bronchitis virus (IBV) dissemination is largely unknown. We first assessed the effect of IBV replication in the chicken testes. Ten-week-old males were inoculated with Arkansas (Ark) or Massachusetts (Mass) IBV virulent strains. Seven days postinoculation (

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 ...

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.

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

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 ...

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.

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.
