|Description:||This historic 1963 photograph depicted laboratorian, Charlotte Patton, as she was labeling vials containing Lowenstein-Jensen growth medium (LJ medium) for subsequent culture studies. LJ medium is commonly used when culturing Mycobacterium spp., including Mycobacterium tuberculosis.|
At the time of this photograph, what is now known as Centers for Disease Control and Prevention (CDC), was until 1970, then known as the Communicable Disease Center.
Modern day protocols now call for the laboratorian executing such tasks, to wear personal protective equipment (PPE) including safety goggles, gloves, and a face mask. PPE, as defined by the Occupational Safety and Health Administration, or OSHA, is “specialized clothing or equipment, worn by an employee for protection against infectious materials.”
