Strategies in progress to control Campylobacter at the farm level.

Strategy	Principle	Advantage	Drawback
Vaccination	Improvement of the immune response against Campylobacter	Easy to use	Antigenic variability of Campylobacter strains
Bacteriophage therapy	Use of specific bacterial virus to kill Campylobacter	Rapid action	Selection of resistant Campylobacter strains Production cost Diversity of Campylobacter strains
Bacteriocin treatment	Use of bacteria-produced antimicrobial compounds against Campylobacter	Easy to use	Production cost Variable sensitivity of Campylobacter strains
Prebiotics	Incorporation of feed additives to improve beneficial avian gut microbiota	Easy to use Production cost	Dependence on the avian gut microbiota
Probiotics	Administration of beneficial microorganisms with anti-Campylobacter activity	Easy to produce and to use Production cost Mix of multiple species Different ways of inhibiting Campylobacter	Variable sensitivity of Campylobacter strains
