Extract

The association of salmonella infections with the consumption of poultry products and the fact that in the live bird the Salmonella carriage is mainly asyptomatic have led to a demand for finding ways of preventing infection of commercially reared poultry and product contamination (Revolledo et al., 2006). One approach is the use of probiotics. The probiotic properties of lactic acid bacteria have been widely studied. Their capacity for adhesion to mucus, ability to autoaggregate and potential for coaggregation with pathogenic bacteria are potential mechanisms for providing a competitive advantage in the intestinal microbiota (Ghadban et al, 2002) and forming a barrier that prevents colonization of pathogenic microorganisms (Kos et al, 2003). In this study, a total of 53 lactic acid bacteria (LAB) were isolated from the contents of the crop, caecum and small intestine, and from the mucosa of the crop, jejunum and ileum of three organically farmed chickens, were examined for autoaggregation and coaggregation with Salmonella enteritidis.
