Abstract:
Laboratory-acquired infection (LAI) is an important issue in laboratory biosafety for pathogenic microorganism, which aims to prevent the spread of infectious pathogens and protect laboratory personnel from potentially harmful microorganisms. Previous LAI reports provided a source of information for understanding the transmission routes and therapies helping to develop targeted prevention and response programs and to comprehensively ensure the biosafety of laboratories. In this study, from the perspective of the transmission routes of agents, the biosafety risks were discussed from four aspects: skin, eye, or mucous membrane exposure, contaminated sharp inoculation or bites from infected animals and arthropod vectors, ingestion or hand-to-mouth exposure, and inhalation of infectious aerosols. The development and evolution of LAI were reviewed, and appropriate countermeasures and suggestions were proposed accordingly.
Insights
Laboratory-acquired infections (LAI) pose risks to personnel handling pathogenic microorganisms. This study reviews LAI transmission routes and proposes countermeasures to enhance laboratory biosafety and prevent infections.
Area of Science:
- Microbiology
- Laboratory Biosafety
- Infectious Disease Epidemiology
Background:
- Laboratory-acquired infections (LAI) are a significant concern in microbiological laboratories.
- Understanding LAI transmission is crucial for developing effective prevention and response strategies.
- Previous reports inform biosafety protocols and personnel protection.
Purpose of the Study:
- To analyze biosafety risks associated with laboratory-acquired infections (LAI) based on agent transmission routes.
- To review the historical development and evolution of LAI.
- To propose targeted countermeasures for enhancing laboratory biosafety.
Main Methods:
- Review of previous LAI reports and literature.
- Analysis of biosafety risks categorized by four primary transmission routes: exposure, inoculation/bites, ingestion, and inhalation.
- Examination of LAI development and evolution.
Main Results:
- Identified four key transmission routes for laboratory-acquired infections: skin/eye/mucous membrane exposure, sharps/animal/arthropod exposure, ingestion, and aerosol inhalation.
- Reviewed the historical progression of LAI.
- Outlined specific risks associated with each transmission pathway.
Conclusions:
- Effective laboratory biosafety requires comprehensive understanding of LAI transmission routes.
- Targeted prevention and response programs are essential for mitigating risks.
- Proactive measures and continuous review of LAI evolution are necessary to ensure personnel safety.
