Listeria monocytogenes Infection (cont.)
Treatment for listeriosis includes intravenous antibiotics, as well as
supportive care. The prompt initiation of antibiotics when the diagnosis is
suspected or confirmed can hasten recovery and prevent the more serious
potential complications sometimes encountered with listeriosis.
(Principen) is generally considered the antibiotic of choice, though there
are other acceptable antibiotic choices.
- Involve an infectious disease specialist to assist with appropriate
antibiotic selection and duration of treatment.
- The duration of treatment with antibiotics varies with the severity of
illness and the particular areas involved with disseminated infection.
- Supportive care
- Intravenous fluids to prevent dehydration or to maintain an adequate blood
pressure may be necessary.
- Intravenous medications for nausea and/or vomiting may be administered.
- Patients with low blood pressure may require intravenous medications to
increase their blood pressure (pressors).
- Patients with severe listeriosis may require mechanical ventilation
(breathing machine) for respiratory support.
Most authorities believe that individuals, even those at high-risk, who
ingest food products contaminated with Listeria monocytogenes do not require
treatment if they do not have any signs or symptoms of infection. However,
careful consideration must be taken in the pregnant patient, as listeriosis can
be potentially devastating to the fetus and newborn.
