Sequential intracoelomic and intrabursal immunization of chickens with inactivated Mycoplasma gallisepticum bacterin and iota carrageenan adjuvant.
Chickens immunized by sequential intracoelomic (analogous to intraperitoneal route in mammals) and intrabursal (i.c./i.b.) routes with inactivated Mycoplasma gallisepticum (MG) bacterin mixed with 0.2% iota carrageenan (iCGN) as an adjuvant were resistant to airsacculitis induced by a subsequent aerosol challenge with virulent R strain MG. In contrast, immunization by the i.c./i.b. routes with inactivated bacterin without the adjuvant or with 0.2% iCGN did not confer significant protection. Chickens immunized by the i.c./i.b. routes with the adjuvanted bacterin had increased levels of circulating and local anti-MG IgG but not IgM or IgA. Tracheal populations of MG were reduced when compared with unimmunized controls.
