Infection with Listeria monocytogenes meningoencephalitis: A case report
1Department of Nursing, Shanghai Sixth People's Hospital, Shanghai 200233, China.
Background:
Listeria meningitis is an infectious disease of the central nervous system caused by Listeria monocytogenes. This bacterium is widely present in the natural environment and can be transmitted through channels such as food and water. Patients usually show symptoms such as fever, headache, and neck stiffness. In severe cases, coma, convulsions, or even death may occur. Traditional diagnostic methods, such as cerebrospinal fluid (CSF) culture and serological tests, have certain limitations. Although CSF culture is the "gold standard" for diagnosis, it is time-consuming and has a relatively low positivity rate. Serological detection may also result in false positive or false negative results. The emergence of metagenomic sequencing (mNGS) technology has led to a significant breakthrough in diagnosing Listeria meningitis, allowing quick and accurate detection of various pathogens in samples.
Case Summary:
Here, we present the case of a previously healthy 64-year-old woman diagnosed with Listeria meningitis using mNGS. She was successfully treated with intravenous ampicillin and meropenem, without any complications.
Conclusion:
Listeria meningitis must be considered, especially in patients who fail to show improvement with first-line antibiotic treatments. mNGS significantly reduces the diagnosis time, supporting timely treatment of patients.
Insights
Metagenomic sequencing (mNGS) aids rapid Listeria meningitis diagnosis. This approach supports timely treatment for patients, especially those unresponsive to initial therapies.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Listeria meningitis is a severe CNS infection caused by *Listeria monocytogenes*, a ubiquitous bacterium.
- Traditional diagnostics like CSF culture and serology have limitations including time, low positivity rates, and potential inaccuracies.
- Metagenomic sequencing (mNGS) offers a significant advancement for rapid and accurate pathogen detection in infectious meningitis.
Observation:
- A case study involving a previously healthy 64-year-old woman diagnosed with Listeria meningitis.
- The diagnosis was achieved using metagenomic sequencing (mNGS).
Findings:
- Metagenomic sequencing enabled a quick and accurate diagnosis of Listeria meningitis.
- The patient received successful treatment with intravenous ampicillin and meropenem.
Implications:
- Listeria meningitis should be suspected in patients with refractory symptoms to first-line antibiotics.
- mNGS technology accelerates diagnosis, facilitating prompt and effective patient treatment.
