Implementing an Organizational Culture of Biosafety and Biosecurity in the ŞAP Institute.

An organizational culture of biosafety and biosecurity is critical for effective management of transboundary animal diseases. One essential aspect of this work is keeping important pathogens studied in veterinary laboratories under control. Türkiye is among the countries that are both endemic and disease-free for foot-and-mouth disease (FMD) virus, and it has a unique institute dedicated to FMD diagnosis, control, and vaccine production.

Short-Term Use Biocontainment Bubbles: Innovative Source Containment of Potentially Infectious SARS-CoV-2 Aerosols.

Introduction: This article will review the processes utilized to develop simple effective containment engineering controls. Short-Term Use Biocontainment Bubbles-Yale (STUBB-Ys), as Yale refers to them, were designed, built, tested, and implemented to protect members of the Yale University community from exposure to SARS-CoV-2 aerosols. STUBB-Ys were designed and created in conjunction with end users, constructed by Environmental Health and Safety (EHS) or partner groups, and tested onsite after installation to verify effective operation and containment.

Biorisk Management Features of a Temporary COVID-19 Hospital.

Introduction: Yale University designed and constructed a temporary field hospital for 100 COVID-19 symptomatic patients. Conservative biocontainment decisions were made in design and operational practices. Objectives of the field hospital included the safe flow of patients, staff, equipment and supplies, and obtaining approval by the Connecticut Department of Public Health (CT DPH) for opening as a field hospital.

Neuroinvasion of SARS-CoV-2 in human and mouse brain.

Although COVID-19 is considered to be primarily a respiratory disease, SARS-CoV-2 affects multiple organ systems including the central nervous system (CNS). Yet, there is no consensus on the consequences of CNS infections. Here, we used three independent approaches to probe the capacity of SARS-CoV-2 to infect the brain.

Although COVID-19 is considered to be primarily a respiratory disease, SARS-CoV-2 affects multiple organ systems including the central nervous system (CNS). Yet, there is no consensus whether the virus can infect the brain, or what the consequences of CNS infection are. Here, we used three independent approaches to probe the capacity of SARS-CoV-2 to infect the brain.

Procedures for Flow Cytometry-Based Sorting of Unfixed Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infected Cells and Other Infectious Agents.

In response to the recent COVID-19 pandemic, many laboratories are involved in research supporting SARS-CoV-2 vaccine development and clinical trials. Flow cytometry laboratories will be responsible for a large part of this effort by sorting unfixed antigen-specific lymphocytes. Therefore, it is critical and timely that we have an understanding of risk assessment and established procedures of infectious cell sorting.

So You Want to Start an Institutional Biosafety Committee.

Introduction: The number of institutions engaging in research with potentially biohazardous materials has increased, indicating a need for newly formed Institutional Biosafety Committees (IBCs) in the United States and for similar biorisk management committees located outside the United States. Our institution identified the need for an IBC due to the growth of pertinent activities on campus.

Objectives: This article shares our experiences creating a new IBC at our institution from September 2017 to April 2019.

Update of Arthropod Containment Guidelines.

The American Society of Tropical Medicine and Hygiene's American Committee of Medical Entomology has released their updated edition (Version 3.2) of the Arthropod Containment Guidelines. The Guidelines were written to provide pertinent risk assessment and risk management information for the safe handling and rearing of arthropods used in research.

International Society for the Advancement of Cytometry cell sorter biosafety standards.

Flow cytometric cell sorting of biological specimens has become prevalent in basic and clinical research laboratories. These specimens may contain known or unknown infectious agents, necessitating precautions to protect instrument operators and the environment from biohazards arising from the use of sorters. To this end the International Society of Analytical Cytology (ISAC) was proactive in establishing biosafety guidelines in 1997 (Schmid et al.

Institutional responsibilities in contamination control in research animals and occupational health and safety for animal handlers.

The mechanisms for controlling microbial contamination in research animals are similar to those for preventing exposure among animal handlers to naturally occurring pathogens, research-related biohazards, or animal allergens. Research and resource preservation are the primary goals of each approach, and an appropriate assessment of risk is their foundation. The identification of potential risks enables the implementation of relevant risk management or control measures.

General guidelines for experimenting with HIV.

Performing experiments using human immunodeficiency virus (HIV)-infected materials represents a potential biological hazard for the investigator. An intensive training program for laboratory personnel must always precede the actual execution of research involving manipulation of HIV. In addition, appropriate sterile tissue culture techniques are absolute prerequisites for producing meaningful experiments and for achieving safe working conditions.

Containment capabilities of animal transfer stations.

Animal-transfer and cage-changing stations are portable downdraft-filtered clean benches that have been specifically modified for small-rodent handling and cage changing from two or more sides, and that are advertised by their manufacturers as providing improved laboratory animal allergen control. The authors evaluated the dust containment capability of three such devices under exaggerated challenge conditions, compared design features, and conclude that animal-transfer stations can be a useful addition to an institutional laboratory animal allergy control program.
