2 Answer key Lesson 1.1 – Gram Stain

3 Activity 1 Significance of Gram stain: Gram stain is the main stain procedure in Microbiology. It enables us to know several things about bacteria in the smear: - GRAM-STAIN REACTION - SHAPE - ARRANGEMENTS of bacteria Bacteria are divided into two large groups depending on their Gram- stain reaction: the so-called Gram-positive (GP) that remains coloured after the decolouration procedure and the Gram-negative (GN) that do not retain the dye and take the colour of the counterstain. Those differences rely on the basis of cell wall structures. Considering together Gram reaction and shape we may set the four big groups of bacteria: GP bacilli, GP cocci, GN bacilli, and GN cocci.
