[Listeria monocytogenes infections--ten years' experience]
1Infectious Disease Unit, Bnai Zion Medical Center, Haifa.
Abstract:
7 cases of listeriosis were diagnosed here between 1988-1997 (6 in last 3 years), or 2.94/100,000 admissions. 2 elderly patients suffered from meningitis and 2 pregnant women presented with premature contractions, 1 of whom delivered a premature, infected baby. 2 other patients had fever and gastroenteritis. Listeria monocytogenes was isolated from blood in 4, CSF in 2 and the placenta in 1. It was isolated from those with bacterial meningitis. All patients recovered. Both increased awareness for prevention and better diagnosis are essential to reduce morbidity from this unusual pathogen.
Insights
Listeriosis diagnoses increased significantly in recent years, with severe cases including meningitis and premature births. Early detection and prevention are crucial for managing this rare bacterial infection.
Area of Science:
- Infectious Diseases
- Bacteriology
- Clinical Medicine
Context:
- Listeriosis, caused by Listeria monocytogenes, is an uncommon but serious infection.
- A notable increase in listeriosis cases was observed in the latter part of the study period (1988-1997).
- The study highlights the diverse clinical presentations and potential severity of listeriosis.
Purpose:
- To report on the incidence and clinical characteristics of listeriosis cases.
- To identify patient demographics and associated risk factors.
- To emphasize the importance of heightened awareness and improved diagnostic strategies for listeriosis.
Summary:
- Seven cases of listeriosis were diagnosed between 1988 and 1997, with a sharp rise in the last three years.
- Affected individuals included elderly patients with meningitis, pregnant women experiencing premature contractions, and those with gastroenteritis.
- Listeria monocytogenes was identified in blood, cerebrospinal fluid (CSF), and placental samples, confirming invasive disease.
Impact:
- The findings underscore the need for increased clinical vigilance and prompt diagnosis of listeriosis.
- Effective prevention strategies are essential to mitigate the morbidity associated with this pathogen.
- Early recognition and management can improve patient outcomes and reduce healthcare burdens.
