This historic 1977 photograph depicted a laboratory technician, who was in the process of performing a parasitological exam on a polyvinyl alcohol (PVA) fixed specimen. At this point in the preparation process, the tech’s right hand was manipulating a long, wooden probe against a glass microscope slide held in her left hand. The probe had extracted a bit of the contents from the PVA specimen container, pictured here. Also pictured, was a glass cylinder containing numerous, unused probes, and a box of unused glass slides. Modern day protocols call for laboratory workers, performing tasks inside the laboratory environment, to wear the appropriate personal protective equipment, including disposable latex gloves.
