Laboratory-acquired meningococcal disease--United States, 2000
Abstract:
Neisseria meningitidis is a leading cause of bacterial meningitis and sepsis among older children and young adults in the United States. N. meningitidis usually is transmitted through close contact with aerosols or secretions from the human nasopharynx. Although N. meningitidis is regularly isolated in clinical laboratories, it has infrequently been reported as a cause of laboratory-acquired infection. This report describes two probable cases of fatal laboratory-acquired meningococcal disease and the results of an inquiry to identify previously unreported cases. The findings indicate that N. meningitidis isolates pose a risk for microbiologists and should be handled in a manner that minimizes risk for exposure to aerosols or droplets.
Insights
Neisseria meningitidis can cause fatal laboratory-acquired infections. Microbiologists must handle these bacteria carefully to prevent exposure to infectious aerosols and droplets.
Area of Science:
- Microbiology
- Infectious Diseases
- Public Health
Background:
- Neisseria meningitidis is a primary cause of bacterial meningitis and sepsis in the US, particularly among young adults.
- Transmission typically occurs via close contact with respiratory aerosols or secretions.
Observation:
- Two probable cases of fatal laboratory-acquired meningococcal disease are described.
- An inquiry was conducted to identify previously unreported cases of laboratory-acquired N. meningitidis infections.
Findings:
- Neisseria meningitidis isolates pose a significant risk for laboratory personnel.
- Handling procedures must be updated to minimize exposure risks.
Implications:
- Enhanced safety protocols are crucial in clinical laboratories handling N. meningitidis.
- Awareness of laboratory-acquired infection risks is essential for microbiologists.
