Gram staining remains one of microbiology’s most essential techniques, offering rapid differentiation between Gram-positive and Gram-negative bacteria. By exploiting differences in cell wall structure ...

Recently we have done two differential stains, the Gram stain and the Acid Fast stain. Both stains differentiate between bacteria chemically. The two staining techniques of Lab 4 differentiate by ...

Gram staining, first developed in 1884 by Hans Christian Gram, remains a foundation of microbiology for separating bacteria into Gram-positive and Gram-negative groups. This simple yet powerful test ...

After more than 130 years, scientists may finally have figured out how a common laboratory method for identifying bacteria works. Invented by Hans Christian Gram in 1884 and thus known as the gram ...

Two years ago, a group of infants died at the university hospital and it was found to be Gram-negative bacteria that caused their death. The Gram-negative bacteria turn into pink color and ...
