Abstract

<em>Listeria monocytogenes </em>is a Gram-positive, rod-shaped bacterium that can cause outbreaks through contaminated food. This report describes two cases of <em>L. monocytogenes </em>bacteremia successfully treated with a combination of meropenem and gentamicin. Both patients had underlying malignancies-multiple myeloma and breast cancer. Neither reported consuming unpasteurized milk or food from external sources. No relapse occurred in either case during a 6-month follow-up period. In conclusion, while <em>L. monocytogenes </em>bacteremia without associated meningitis or gastroenteritis is uncommon, it can occur in immunocompromised individuals. To our knowledge, these are the first reported cases of <em>L. monocytogenes </em>bacteremia in our country.
