Hans Christian Gram: The inventor of the Gram stain
Hans Christian Gram, credited as the inventor of the Gram staining technique, was a pioneering biologist who devised the system of classification which led to as many as 30,000 formally named species of bacteria being investigated. Gram, working with German pathologist and microbiologist Karl Friedländer, devised the technique in Berlin in the early 1880s.
Today marks the 168th birth anniversary of Hans Christian Gram. The Gram stain allows one to distinguish between Gram-positive and Gram-negative bacteria based on the bases of differential staining with a crystal violet-iodine complex and a safranin counterstain.
In honor of his birth anniversary, Hardy Diagnostics demonstrates how to make the perfect Gram stain.
