Poultry DNA vaccination against bacteria.

Pathogen	Host	Antigen	Route	Major immunological outcomes	References
Chlamydophila psittaci	Turkeys	MOMP	IM + IN Or ID Or IM	Induction of IgA, IgM and IgG. Induction of lymhoproliferation. Prevention, but not always abolition, of severe clinical symptoms upon challenge. Able to circumvent maternal antibodies.	[67], [71], [87], [95], [100]
Campylobacter jejuni	Chickens	Flagellin	IN	Induction of antibodies in the serum and intestinal mucosa. Reduction in cecum shedding of about 2 logs on days 18–21 after challenge.	[68]
Avian pasteurella multocida	Chickens	OmpH and OmpA	IM	Production of serum IgG antibodies. Induction of lymphoproliferation and IFN-γ. 70–75% of survivors after challenge.	[69]
