<strong><em>General Information:</em></strong></p>
<p>
<em>-Listeria</em> can cause serious infections in vulnerable groups: adults >65 years old, pregnant women, newborns, immunocompromised</p>
<p>
-In a recent CDC report, infection with <em>Listeria</em> was associated with a 20% mortality rate.</p>
<p>
<strong><em>Clinical Presentation:</em></strong></p>
<p>
- History of cantaloupe, soft cheese, or raw produce ingestion</p>
<p>
- Non-specific symptoms: fever, myalgias, occasionally preceded by GI symptoms</p>
<p>
-Can have headache, stiff neck, confusion, AMS, miscarriage or stillbirth in pregnant women</p>
<p>
<strong><em>Diagnosis:</em></strong></p>
<p>
- Blood, CSF, or amniotic fluid culture showing <em>Listeria monocytogenes</em></p>
<p>
- <em>Listeria</em> is a reportable disease</p>
<p>
<strong><em>Treatment:</em></strong></p>
<p>
- Ampicillin and Penicillin G are the drugs of choice</p>
<p>
- Add gentamycin in CSF infection, endocarditis, the immunocompromised, and neonates.</p>
<p>

<em>Listeria </em>infections have a high mortality rate and can be found worldwide. Suspect in patients who have febrile syndromes and travel to areas where they may consume unpasteurized cheese.</p>
