Relationship between mucosal antibodies and immunity against avian infectious bronchitis virus
(2014-01-01)
Immunity against avian infectious bronchitis virus (IBV) was assessed in specific pathogen free (SPF) chickens vaccinated at age of three weeks with H120 attenuated vaccine strain and, after three weeks, by measuring the ...
Avian infectious bronchitis: viral persistence in the harderian gland and histological changes after eyedrop vaccination
(American Association of Avian Pathologists, 1996)
The histological changes in the harderian gland (HG) induced by the attenuated H-120 infectious bronchitis virus (IBV) vaccine strain and the persistence of this virus in the stroma of the gland was evaluated in chickens ...
Nephritis associated with a S1 Variant Brazilian isolate of infectious bronchitis virus and vaccine protection test in experimentally infected chickens
(2013-01-01)
Infectious bronchitis virus (IBV) induces a significant negative impact on poultry production worldwide, specially due to the continuous emergence of viral variants. This virus causes damage to the respiratory tract, and ...
Detection of infectious bronchitis virus in experimentally infected chickens by an antigen-competitive ELISA
(2001-02-07)
An antigen-competitive enzyme-linked immunosorbent assay (Ag-C-ELISA) was developed for the detection of infectious bronchitis virus (IBV) antigens, M41 strain, in tissues from experimentally infected chickens, or in ...

Desenvolvimento e avaliação da eficácia de uma vacina inativada do vírus da bronquite infecciosa aviária encapsulado em nanopartículas de quitosana
(Universidade Estadual Paulista (Unesp), 2017-11-17)
Vacinação é a forma mais eficiente para prevenir e controlar a infecção pelo vírus da bronquite infecciosa (VBI). Vacinas formuladas com nanopartículas de quitosana têm sido utilizadas como sistema de entrega de antígenos ...
Avian infectious bronchitis: specific lachrymal IgA level and resistance against challenge
(1994)
Since circulating antibody titres against infectious bronchitis virus (IBV) often correlate poorly with protection against re‐infection, the lachrymal specific IgA level of IBV vaccinated chickens was evaluated as an ...
