Serological tests applied in poultry flocks can be a valuable tool in assessing health of hens. One obstacle in making this assessment is that results of serological tests in a given flock are not always correlated with results of bacteriological tests. The aim of this study was to determine dependencies between the level of antibodies in egg yolk and the contamination of egg contents (whites and yolks) with Salmonella Enteritidis bacilli. Infected birds were also treated with selected antibiotics. It was determined that Salmonella Enteritidis was not found in experimentally infected laying hens until day 12 post-inoculation. The results of the study also suggest the existence of relation between the level of anti-Salmonella antibodies in egg yolks and the frequency of isolation of Salmonella from eggs. It was also found that the lowest level of yolk antibodies was found in the group of birds treated with enrofloxacin.
