Evolutionary implications of Avian Infectious Bronchitis Virus (AIBV) analysis [PDF]

Cell Research, 2006
For developing efficient vaccines, it is essential to identify which amino acid changes are most important to the survival of the virus. We investigate the amino acid substitution features in the Avian Infectious Bronchitis Virus (AIBV) antigenic domain of a vaccine serotype (DE072) and a virulent viral strain (GA98) to better understand adaptive ...

Immune electron microscopy of avian infectious bronchitis virus serotypes [PDF]

Journal of Clinical Microbiology, 1978
An immune electron microscopy agglutination technique in which emphasis is placed upon the importance of antigen-antibody equivalence has been developed as a possible method for the serotyping of avian infectious bronchitis viruses. The Connecticut and Massachusetts 41 serotypes were used as a model system.

Antigenic variation in strains of avian infectious bronchitis virus [PDF]

Archiv f�r die gesamte Virusforschung, 1971
Fifteen british field strains of IBV were compared using cross serum neutralization tests in embryonated eggs with seven standard reference strains of IBV. While the British field strains were considered to form a relatively homogeneous group considerable antigenic variation did occur. It was considered that it was not feasible at this time to describe

HEMAGGLUTININS OF AVIAN INFECTIOUS BRONCHITIS VIRUS

Uirusu, 1970
On the gel filtration, using Sepharose 2B, of the supernatant from ultracentrifugation hf homogenized chorioallantoic membrane of infectious bronchitis virus infected chicken embryos, a fraction, which was not detected in the chromatographic pattern of similar material from normal chicken embryos, bearing hemagglutinating activity first appeared, and a

Productive replication of nephropathogenic infectious bronchitis virus in peripheral blood monocytic cells, a strategy for viral dissemination and kidney infection in chickens [PDF]

, 2016
In the present study, the replication kinetics of nephropathogenic (B1648) and respiratory (Massachusetts-M41) IBV strains were compared in vitro in respiratory mucosa explants and blood monocytes (KUL01(+) cells), and in vivo in chickens to understand ...

New oligonucleotide microarray for rapid diagnosis of avian viral diseases

Virology Journal, 2017
Background We developed a new oligonucleotide microarray comprising 16 identical subarrays for simultaneous rapid detection of avian viruses: avian influenza virus (AIV), Newcastle disease virus (NDV), infection bronchitis virus (IBV), and infectious ...

Extensive coronavirus-induced membrane rearrangements are not a determinant of pathogenicity [PDF]

, 2016
Positive-strand RNA (+RNA) viruses rearrange cellular membranes during replication, possibly in order to concentrate and arrange viral replication machinery for efficient viral RNA synthesis.
