In Lab 2 you were introduced to simple staining techniques that enable microbiologists to observe the morphological characteristics of bacteria. Although simple stains are useful, they do not reveal ...

The cell wall of most bacteria has an overall net negative charge and thus can be stained directly with a single basic (positively charged) stain or dye. This type of stain allows us to observe the ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria.
