Experimental infection of laying hens with highly pathogenic Salmonella Enteritidis previously isolated from poultry farm

Salmonella enterica serovar Entertitidis (SE) is one of the main causes of food borne diseases, transmitted by eggs or egg products. The aim of the present study was to investigate the prevalence of SE in specimens collected from experimentally infected laying hens. In the two trials two lines of commercial laying hens at onset of the lay were orally inoculated with a single dose of 1.2x109 CFU of highly pathogenic SE. After infection the inoculated bacteria were recovered in all hens. Despite the fact that all hens became infected, we found a low number of positive eggs.
