The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels in a publication referred to as Biosafety in Microbiological and Biomedical Laboratories (BMBL).

Biosafety level 4 laboratories are designed for diagnostic work and research on easily respiratory-acquired viruses which can often cause severe and/or fatal disease. What follows is a list of select agents that have specific biocontainment requirements according to US federal law.
The United States Centers for Disease Control and Prevention (CDC) categorizes various diseases in levels of biohazard, Level 1 being minimum risk and Level 4 being extreme risk. Laboratories and other facilities are categorized as BSL (Biosafety Level) 1–4 or as P1 through P4 for short (Pathogen or Protection Level). [citation needed]
After sampling water sites around the country, the Surfrider Foundation, an ocean protection advocacy organization, found unsafe levels of fecal contamination at 19% of the 9,095 water samples. Of ...
The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels. [8] In the European Union, the same biosafety levels are defined in a directive. [9]
Biosafety level refers to the stringency of biocontainment precautions deemed necessary by the Centers for Disease Control and Prevention (CDC) for laboratory work with infectious materials. Typically, institutions that experiment with or create potentially harmful biological material will have a committee or board of supervisors that is in ...
P. vulgatus is a biosafety level 1 organism that can be grown in anaerobic laboratory conditions at 37 °C with a growth time [vague] of 1–2 days. [7] P. vulgatus can be exposed to 0.03% dissolved oxygen with no effect on growth, and it is believed that anaerobes like P. vulgatus possess specific mechanisms to survive or cope with small ...
