Listeriosis (Listeria monocytogenes)
1999 Case Definition
CSTE Position Statement Number: 09-ID-46
Clinical description
In adults, invasive disease caused by Listeria
monocytogenes manifests most commonly as meningitis or
bacteremia; infection during pregnancy may result in fetal
loss through miscarriage or stillbirth, or neonatal meningitis
or bacteremia. Other manifestations can also be observed.
Laboratory criteria for diagnosis
- Isolation of L. monocytogenes from a normally
sterile site (e.g., blood or cerebrospinal fluid [CSF] or, less
commonly, joint, pleural, or pericardial fluid)
- In the setting of miscarriage or stillbirth, isolation of L. monocytogenes from
placental or fetal tissue
Case classification
Confirmed: A clinically
compatible case that is laboratory-confirmed
Comment:
The usefulness of other laboratory methods such fluorescent
antibody testing or polymerase chain reaction to diagnose invasive
listeriosis has not been established.
The 1999 case definition appearing on this page was re-published in the 2003 CSTE position statement 03-ID-01 and in the 2009 CSTE position statement 09-ID-46. Thus, the 1999, 2003, and 2010 versions of the case definition are identical.
