Description:This 1981 image depicts a laboratorian seated inside her laboratory at a laminar flow hood in the process of streaking Petri dish culture plates with an unknown specimen. The technician was wearing personal protective equipment (PPE) including a protective face mask, latex gloves, and a full-body laboratory smock. See PHIL 3576 for a color version of this image.
Using different growth media, for a given specimen, produces different colonial growth patterns, depending on the chemical constituents within the media. Antimicrobial agents can also be added to the growth media in order to test the organism’s sensitivity to these additives.
