SPORADIC CASE OF LISTERIOSIS ASSOCIATED WITH THE CONSUMPTION OF A LISTERIA MONOCYTOGENES-CONTAMINATED CAMEMBERT CHEESE

Listeria monocytogenes is an intracellular Gram-positive organism resp onsible for severe infections in both humans and animals, Whereas the food-borne transmission of listeriosis was demonstrated in several out breaks, most cases of listeriosis occur sporadically and are rarely li nked with consumption of contaminated foods. In this paper a case of s epticaemia with L. monocytogenes in a 73-year-old immunocompromised ma n is described, Evidence for the association of this case of listerios is with the consumption of a contaminated 'Camembert' cheese is provid ed by serotyping, esterase typing, DNA macrorestriction patterns analy sis and level of virulence of the isolated strains for mice.
