The microbes in a BSL-4 lab are dangerous and exotic, posing a high risk of aerosol-transmitted infections. Infections caused by these microbes are frequently fatal and without treatment or vaccines. Two examples of microbes worked with in a BSL-4 laboratory include Ebola and Marburg viruses.
What are BSL-4 organisms?
Biohazard Level 4 usually includes dangerous viruses like Ebola, Marburg virus, Lassa fever, Bolivian hemorrhagic fever, and many other hemorrhagic viruses found in the tropics.
What are Level 4 diseases?
Diseases that have high fatality rates and have no known treatments are considered level 4 diseases. An example of a level 4 disease is Ebola virus, a disease that causes headache, muscle pain, fever, impaired liver and kidney function, and in some cases, death.
What are Level 4 agents?
Level 4. Agents requiring BSL 4 facilities and practices are extremely dangerous and pose a high risk of life-threatening disease. Examples are the Ebola virus, the Lassa virus, and any agent with unknown risks of pathogenicity and transmission. These facilities provide the maximum protection and containment.
How many BSL-4 labs are there?
There are currently only four operational BSL-4 laboratory suites in the United States: at the Centers for Disease Control and Prevention in Atlanta; at the United States Army Medical Research Institute for Infectious Diseases at Fort Detrick in Frederick, Maryland; at the Southwest Foundation for Biomedical Research …
What are the types of BSL-4 laboratories?
The BSL-4 laboratories are of two types; cabinet laboratory where all the work is performed in a Class III biosafety cabinet or similar physical containment with very carefully formulated precautions and suit laboratory where all the laboratory personnel are required to wear full-body, air-supplied suits protective …
What BSL level is anthrax?
anthracis), under biosafety level (BSL) 3 containment conditions.
What diseases are studied in a BSL-4 lab?
Ebola, smallpox, plague—the rogue’s gallery of highly infectious deadly pathogens is frighteningly long and their potential for havoc is great, which is why they can only be studied within the tightly controlled confines of a biosafety level 4 (BSL4) facility.
What Biosafety Level is E. coli?
| Biosafety levels (BSL) | BSL–1 |
|---|---|
| 1. Degree of hazard | Low risk: Well characterized agents not known to cause disease in healthy adult humans |
| 2. Examples | Escherichia coli (laboratory strain) |
| B. Standard microbiological practices | |
| Biosafety levels (BSL) | BSL–1 |
What is a Level 3 laboratory?
Biosafety Level 3 (BSL-3) BSL-3 laboratories are used to study infectious agents or toxins that may be transmitted through the air and cause potentially lethal infections. Researchers perform all experiments in a biosafety cabinet. BSL-3 laboratories are designed to be easily decontaminated.
What BSL is smallpox?
| Viral Agent | BSL |
|---|---|
| Poxvirus – Smallpox* | |
| Poxvirus sp. | 2 |
| Pseudorabies Virus | 2 |
| Rabies Virus | 2/3 |
What BSL level is smallpox?
Smallpox virus is highly infectious. Manipulation of specimen material should be avoided, but if necessary, use Biosafety Level 3 practices.
What are the levels of infectious diseases?
The four biosafety levels are BSL-1, BSL-2, BSL-3, and BSL-4, with BSL-4 being the highest (maximum) level of containment.
What is a Level 4 laboratory?
Biosafety level 4 laboratories are used for diagnostic work and research on easily transmitted pathogens which can cause fatal disease. These include a number of viruses known to cause viral hemorrhagic fever such as Marburg virus, Ebola virus, Lassa virus, and Crimean-Congo hemorrhagic fever.
What are the various biosafety levels?
- Containment. The term containment refers to methods for safely managing infectious materials in the laboratory environment where they are being handled or maintained. …
- Primary containment. …
- Secondary containment. …
- On-site treatment.
What is the difference between BSL 1 and BSL-2 organisms?
The main difference in the work procedures followed in a BSL-1 laboratory and a BSL-2 laboratory is that employees in a BSL-2 laboratory will use a BSC as a primary barrier for potentially hazardous aerosols. … Inside the laboratory, special lab coats, gloves, and face and eye protection should be worn.
What biosafety level is influenza?
Due to the potential for aerosol inhalation and the pathogenicity of influenza A(H7N9) viruses for humans observed to date, respiratory protection is mandatory for activities conducted at Biosafety Level 3 (BSL-3) or when formation of aerosols are anticipated.
What does anthrax look like?
Cutaneous Anthrax *The characteristic rash of anthrax looks like pink, itchy bumps that occur at the site where B. anthracis comes into contact with scratched or otherwise open skin. The pink bumps progress to blisters, which further progress to open sores with a black base (called an eschar).

What biosafety level is designated for organisms that don't usually cause disease in humans?
Biosafety level -1 (BSL-1) is recommended for organisms, which do not cause any diseases to humans. It is used for agents, which pose minimal threat to the laboratory workers, public health and environment.
What BSL is Mycobacterium tuberculosis?
tuberculosis complex should be carried out under Biosafety Level 2 (BSL-2) containment with BSL-3 safety equipment and work practices.
What does a Biosafety Level 2 mean?
Biosafety Level 2 (BSL-2) is suitable for experiments involving agents of moderate potential hazard to personnel and the environment. For example: Microorganisms of low biohazard potential, such as those in Risk Group 2 or BSL-2.
Who BSL 3?
Biosafety level 3 (BSL-3) is applicable to clinical, diagnostic, teaching, research, or production facilities where work is performed with agents that may cause serious or potentially lethal disease through inhalation, to the personnel, and may contaminate the environment.
What is a Level 3 cause?
Level 3 includes specific causes such as tuberculosis, stroke, and road injuries. In some cases, these Level 3 causes are the most detailed classification, whereas for others a more detailed category is specified at Level 4.
