A. INTRODUCTION TO STAINING
DISCUSSION
In our laboratory, bacterial morphology (form and structure) may be examined in two ways:
- by observing living unstained organisms (wet mount), or
- by observing killed stained organisms.
- see greater contrast between the organism and the background,
- differentiate various morphological types (by shape, arrangement, gram reaction, etc.),
- observe certain structures (flagella, capsules, endospores, etc.).
The procedure for heat fixation is as follows:
Shape =Arrangement =
