Le Duc, J. The "A" designation is used for research involving whole animals infected with viable pathogens. For the purpose of infected animal research, three levels of containment are used at the Hutch. Research involving the use of whole animals containing recombinant DNA and viable pathogens is identified using the "A" designation.
Biohazard Safety Without knowing other factors and assuming good microbiological laboratory practices, a biosafety level can be determined as follows: Check the BMBL for the agent and the CDC recommendations for it. Use the risk groups in the NIH Guidelines as default values.
Conduct a risk assessment see Section 3. Table 3. The agent and protocol hazards to be considered include the following: Agent Hazards Pathogenicity Virulence Infectious dose Route of transmission Agent stability Host range Protocol Hazards Agent concentration Manipulations that produce droplets and aerosols Manipulations involving sharps Manipulations with high potential for spills and splashes Exposure to zoonotic diseases of experimental animals Alteration of agent hazard 3.
Risk Group 2 RG2 : An agent associated with human disease which is rarely serious and for which preventive or therapeutic interventions are often available. Risk Group 3 RG3 : An agent that is associated with serious or lethal human disease for which preventive or therapeutic interventions may be available high individual risk but low community risk. Risk Group 4 RG4 : An agent that is likely to cause serious or lethal human disease for which preventive or therapeutic interventions are not usually available high individual risk and high community risk.
Other: Agents not listed in Risk Groups 2, 3, and 4 are not automatically or implicitly classified in RG1. A risk assessment must be conducted based on the known and potential properties of the agents and their relationship to agents that are listed.
Recombinant DNA molecules containing less than one-half of any eukaryotic viral genome all viruses from a single family being considered identical that are propagated and maintained in cells in tissue culture. Experiments which use E. Lambda or lambdoid or Ff bacteriophages or nonconjugative plasmids are used as vectors. When a nonconjugative vector is used, the E.

Feedback Feedback. Agents that are not associated with disease in healthy human adults. Standard lab and management practices, including appropriate medical surveillance programs. Not known to be inhalationtransmittable No aerosol production planned. BSL-1 practices plus: - Limited access - Biohazard warning signs - Sharps precautions - Biosafety manual Decontamination of all infectious wastes prior to disposal. Associated with human disease; special precautions required for some agents. There is a need for a consensus on how proof of biosafety should be shown and documented, in order to sustain and not stifle a flexible capacity to deal with new and well-known pathogens.
This could essentially impede all bio-preparedness actions in the event of unexpected events in the public domain. A recent literature review concluded that deviation from general 'good microbiological practice' is the most frequent cause of laboratory-acquired infections and that training for compliance with procedures and regulations seems to be the best method to avoid such infections 4.
