Presentation Transcript

  1. Risk Group and Biosafety Level

  2. Classification of Infective Agents by Risk Group • Pathogenicity • Infectious Dose • Mode of Transmission • Host Range • Availability of Effective Preventive Measures and Treatment

  3. Classification of Infective Agents by Risk Group

  4. Classification of Containment by Biosafety Levels • Practices and Procedures • Containment Equipment (Primary Barriers) • Containment Facility (Secondary Barriers) Note: CDC/NIH has 4 biosafety level classifications currently in use. Each level is appropriate for: • Operations Performed • Routes of Transmission (ingestion, inoculation, inhalation, mucous membrane exposure) • Laboratory Function

  5. Risk Group and Biosafety Level Classifications • Not appropriate to use risk group or biosafety level when assessing toxins. • Can be found in the American Biological Safety Association website: www.absa.org/resriskgroup • Risk Groups and Biosafety Levels are not always the same!
