Development and Immunoprotection of Bacterium-like Particle Vaccine against Infectious Bronchitis in Chickens

نویسندگان

چکیده

Infectious bronchitis (IB) is a major threat to the global poultry industry. Despite availability of commercial vaccines, IB epidemic has not been effectively controlled. The exploration novel IBV vaccines may provide new way prevent and control IB. In this study, BLP-S1, bacterium-like particle displaying S1 subunit infectious virus (IBV), was constructed using GEM-PA surface display system. immunoprotective efficacy results showed that BLP-S1 can induce specific IgG sIgA immune responses, providing protection rate 90% against infection in 14-day-old chickens. These suggest potential for development with good immunogenicity immunoprotection.

Immunogenicity and Efficacy of Live Infectious Bronchitis 793/B.08IR Vaccine in SPF Chickens

Infectious bronchitis virus (IBV) has a variety of serotypes with relatively limited cross-protection leading the disease to be a major problem in the poultry industry. The IBV 793/B strain has identified to circulate in Iran; therefore, the development of a specific vaccine to protect against the virulent virus has received attention. In this regard, the live IB 793/B vaccine (793/B.08IR) was ...

Protection of chickens against infectious bronchitis virus with a multivalent DNA vaccine and boosting with an inactivated vaccine

The protective efficacy of DNA plasmids encoding avian infectious bronchitis virus (IBV) S1, N, or M protein was investigated in chickens. Chickens were inoculated monovalently (with plasmid pVAX1-16S1, pVAX1-16M, or pVAX1-16N alone) or multivalently (combination of the three different plasmids, pVAX1-16S1/M/N). A prime-boost immunization protocol against IBV was developed. Chickens were immuni...
