Biosafety Level 1 and Rdna Training
Biosafety Level 1and rDNA Training Office of Biological Safety Biosafety Level 1 and rDNA Training • Difference between Risk Group and Biosafety Level • NIH and UC policy on recombinant DNA • Work conducted at Biosafety Level 1 • UC Code of Conduct for researchers Biosafety Level 1 and rDNA Training What is the difference between risk group and biosafety level? Risk Groups vs Biosafety Level • Risk Groups: Assigned to infectious organisms by global agencies (NIH, CDC, WHO, etc.) • In US, only assigned to human pathogens (NIH) • Biosafety Level (BSL): How the organisms are managed/contained (increasing levels of protection) Risk Groups vs Biosafety Level • RG1: Not associated with disease in healthy adults (non‐pathogenic E. coli; S. cerevisiae) • RG2: Cause diseases not usually serious and are often treatable (S. aureus; Legionella; Toxoplasma gondii) • RG3: Serious diseases that may be treatable (Y. pestis; B. anthracis; Rickettsia rickettsii; HIV) • RG4: Serious diseases with no treatment/cure (Hemorrhagic fever viruses, e.g., Ebola; no bacteria) Risk Groups vs Biosafety Level • BSL‐1: Usually corresponds to RG1 – Good microbiological technique – No additional safety equipment required for biological work (may still need chemical/radiation protection) – Ability to destroy recombinant organisms (even if they are RG1) Risk Groups vs Biosafety Level • BSL‐2: Same as BSL‐1, PLUS… – Biohazard signs – Protective clothing (lab coat, gloves, eye protection, etc.) – Biosafety cabinet (BSC) for aerosols is recommended but not always required – Negative airflow into room is recommended, but not always required Risk Groups vs Biosafety Level • BSL‐3: Same as BSL‐2, PLUS… – Specialized clothing (respiratory protection, Tyvek, etc.) – Directional air flow is required. -
Fibrinogen Binding Sites P336 and Y338 of Clumping Factor a Are Crucial for Staphylococcus Aureus Virulence
Fibrinogen Binding Sites P336 and Y338 of Clumping Factor A Are Crucial for Staphylococcus aureus Virulence Elisabet Josefsson1*, Judy Higgins2, Timothy J. Foster2, Andrej Tarkowski1 1 Department of Rheumatology and Inflammation Research, University of Gothenburg, Go¨teborg, Sweden, 2 Microbiology Department, Moyne Institute of Preventive Medicine, Trinity College, Dublin, Ireland Abstract We have earlier shown that clumping factor A (ClfA), a fibrinogen binding surface protein of Staphylococcus aureus,isan important virulence factor in septic arthritis. When two amino acids in the ClfA molecule, P336 and Y338, were changed to serine and alanine, respectively, the fibrinogen binding property was lost. ClfAP336Y338 mutants have been constructed in two virulent S. aureus strains Newman and LS-1. The aim of this study was to analyze if these two amino acids which are vital for the fibrinogen binding of ClfA are of importance for the ability of S. aureus to generate disease. Septic arthritis or sepsis were induced in mice by intravenous inoculation of bacteria. The clfAP336Y338 mutant induced significantly less arthritis than the wild type strain, both with respect to severity and frequency. The mutant infected mice developed also a much milder systemic inflammation, measured as lower mortality, weight loss, bacterial growth in kidneys and lower IL-6 levels. The data were verified with a second mutant where clfAP336 and Y338 were changed to alanine and serine respectively. When sepsis was induced by a larger bacterial inoculum, the clfAP336Y338 mutants induced significantly less septic death. Importantly, immunization with the recombinant A domain of ClfAP336SY338A mutant but not with recombinant ClfA, protected against septic death. -
Biosafety Manual 2017
Biosafety Manual 2017 Revised 6/2017 Policy Statement It is the policy of Northern Arizona University (NAU) to provide a safe working environment. The primary responsibility for insuring safe conduct and conditions in the laboratory resides with the principal investigator. The Office of Biological Safety is committed to providing up-to-date information, training, and monitoring to the research and biomedical community concerning the safe conduct of biological, recombinant, and acute toxin research and the handling of biological materials in accordance with all pertinent local, state and federal regulations, guidelines, and laws. To that end, this manual is a resource, to be used in conjunction with the CDC and NIH guidelines, the NAU Select Agent Program, Biosafety in Microbiological and Biomedical Laboratories (BMBL), and other resource materials. Introduction This Biological Safety Manual is intended for use as a guidance document for researchers and clinicians who work with biological materials. It should be used in conjunction with the Laboratory-Specific Safety Manual, which provides more general safety information. These manuals describe policies and procedures that are required for the safe conduct of research at NAU. The NAU Personnel Policy on Safety 5.03 also provides guidance for safety in the workplace. Responsibilities In the academic research/teaching setting, the principal investigator (PI) is responsible for ensuring that all members of the laboratory are familiar with safe research practices. In the clinical laboratory setting, the faculty member who supervises the laboratory is responsible for safety practices. Lab managers, supervisors, technicians and others who provide supervisory roles in laboratories and clinical settings are responsible for overseeing the safety practices in laboratories and reporting any problems, accidents, and spills to the appropriate faculty member. -
