    en.wikipedia.org/wiki/Biosafety_level

    Prions, the infectious agents that transmit prion diseases such as vCJD, are typically handled under Biosafety Level 2 or higher. [24] This is due to the lack of any evidence of aerosol transmission and relatively higher infective dose of prion diseases, though some circumstances (such as handling animal-infective prions in a facility which ...

    Microbiological culture is the primary method used for isolating infectious disease for study in the laboratory. Tissue or fluid samples are tested for the presence of a specific pathogen, which is determined by growth in a selective or differential medium. The 3 main types of media used for testing are: [34]
