Avian Infectious Bronchitis Coronavirus Variation and Selection 

Gallardo, Rodrigo (2011-11-30)
Infectious bronchitis virus (IBV) is a highly variable virus, its genetic variation is generated by nucleotide insertions, deletions, or point mutations made by the viral polymerase during virus replication. Another ...

Avian Influenza Adenovirus-Vectored in Ovo Vaccination: Combination with Marek's Disease Vaccine 

Breedlove, Cassandra (2011-08-05)
Protective immunity against avian influenza (AI) can be elicited in chickens in a single-dose regimen by in ovo vaccination with a replication competent adenovirus (RCA)-free human adenovirus serotype 5 (Ad)-vector encoding ...

In Ovo-Vaccination with a Non-Replicating Adenovirus-Vectored Avian Influenza: Maternal Immunity and Effects on Vaccination 

Alexander, Mesonero (2011-11-17)
Protective immunity to avian influenza (AI) virus can be elicited in chickens by in ovo or intramuscular (IM) vaccination with RCA-free adenovirus vector encoding AI virus H5 (AdH5). We evaluated persistence of specific ...

Influence of the Chicken Major Histocompatibility Complex on the Pathogenesis of Bacterial Skeletal Disease, Chicken Infectious Anemia and Infectious Bronchitis 

Joiner, Kellye (2006-12-15)
Genetic resistance to several poultry pathogens has been unequivocally linked to the major histocompatibility B complex (MHC). Relatively few MHC association studies have been conducted during natural disease outbreaks, ...

Novel Infectious Bronchitis Virus Vaccines and Immune Responses 

Zegpi, Ramon (2019-11-25)
Infectious bronchitis virus (IBV) occurs as multiple serotypes and genotypes worldwide. In the United States IBV belonging to the Arkansas (Ark) Delmarva Poultry Industry (DPI) genotype is the most frequently isolated ...

Prevention and Pathogenesis of Avian Infectious Bronchitis: The Role of Infectious Bronchitis Virus Spike Proteins in Cell Attachment and Protective Immunity 

Eldemery, Fatma (2017-12-01)
Infectious bronchitis virus (IBV) evolves by genetic diversity and selection resulting in continuous emergence of new virus phenotypes. Spike (S) protein is responsible for virus entry. The S1 subunit of the S glycoprotein ...

Protective Efficacy of a Recombinant Newcastle Disease Virus against Infectious Bronchitis 

Khalid, Zubair (2021-07-13)
A previous study has reported that Newcastle disease virus (NDV) recombinant LaSota strain (rLS) expressing infectious bronchitis virus (IBV) Arkansas-type (Ark) trimeric spike ectodomain (Se) (rLS/ArkSe) provides suboptimal ...
