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 ...
Infectious bronchitis: Effect of viral doses and routes on specific lacrimal and serum antibody responses in chickens
(American Association of Avian Pathologists, 1997)
An enzyme-linked immunosorbent assay was used to measure the effect of various infectious bronchitis virus (IBV) (strain H-120) vaccine doses and routes of immunization on specific lacrimal and serum antibody responses. ...
Humoral and cell-mediated immune responses to different doses of attenuated vaccine against avian infectious bronchitis virus
(2013-08-01)
The antibody and cellular immune responses against infectious bronchitis virus (IBV) were evaluated at mucosal sites of chickens after immunization with various doses of an attenuated vaccine at 1 day of age. The correlation ...
