  • The Basics of Biocontainment
    technology feature The basics of biocontainment Studying potentially dangerous microbes in animal models of the disease they cause takes some extra considerations, as researchers and staf must perform their work under the careful restrictions of diferent biosafety level laboratories. Jim Kling n early 2020, when the first concerns arose about a SARS-CoV-2 pandemic, Iresearchers at biosafety facilities realized they would soon be pivoting to work with the novel coronavirus. Fortunately, many had previous experience to draw on, such as working with influenza virus or other airborne pathogens, or with SARS-CoV-1. That 2002 outbreak resulted in a more severe, though less transmissible, disease than the current virus. Preprints from Chinese and Asian researchers guided early efforts, said Kenneth Palmer, director of the University of Louisville (UoL) Regional Biocontainment Laboratory and the UofL Center for Predictive Medicine for Biodefense and Emerging Infectious Diseases. The team in Kentucky had also established a ferret model during their Keeping microbes, such as SARS-CoV-2, contained is a critical consideration for those studying work with SARS-CoV-1. “We found that dangerous agents in biosafety facilities. Credit: E. Dewalt, Springer Nature our experience with the ferret model of SARS-CoV-1 was very similar to the published experience [with SARS-CoV-2], and the procedures we are using for research are tiered from biosafety level (BSL) 1 to are reserved for agents with a high fatality are very similar between SARS-CoV1 4. BSL-1 can be used for agents that don’t rate, such as Ebola. They require full body and SARS-CoV2, and avian influenza consistently cause disease.

    Biosafety in Microbiological and Biomedical Laboratories 5th Edition U.S. Department of Health and Human Services Public Health Service Centers for Disease Control and Prevention National Institutes of Health HHS Publication No. (CDC) 21-1112 Revised December 2009 Foreword Biosafety in Microbiological and Biomedical Laboratories (BMBL) quickly became the cornerstone of biosafety practice and policy in the United States upon first publication in 1984. Historically, the information in this publication has been advisory is nature even though legislation and regulation, in some circumstances, have overtaken it and made compliance with the guidance provided mandatory. We wish to emphasize that the 5th edition of the BMBL remains an advisory document recommending best practices for the safe conduct of work in biomedical and clinical laboratories from a biosafety perspective, and is not intended as a regulatory document though we recognize that it will be used that way by some. This edition of the BMBL includes additional sections, expanded sections on the principles and practices of biosafety and risk assessment; and revised agent summary statements and appendices. We worked to harmonize the recommendations included in this edition with guidance issued and regulations promulgated by other federal agencies. Wherever possible, we clarified both the language and intent of the information provided. The events of September 11, 2001, and the anthrax attacks in October of that year re-shaped and changed, forever, the way we manage and conduct work
