The competitive exclusion concept: development and future.
The origin of the competitive exclusion (CE) concept in controlling a Salmonella infantis outbreak in poultry in 1971 and the subsequent development of a commercial treatment product are described. The possible role of CE in salmonella control, current status of the concept and theories relating to the bacteria involved and mechanisms of protection are reviewed. Some observations are made on the need for methodological development and possibilities for extending the scope of CE to other pathogens and types of domestic animal.
