| The small pink bacilli above are Mycobacterium smegmatis, an acid fast bacteria because they retain the primary dye. The darker staining cocci are Staphylococcus epidermidis , a non-acid fast bacterium. |
Acid Fast Stain

Bacterial capsules
 |
| The capsule of Klebsiella pneumoniae is demonstrated here. This is a combination of a negative stain and a simple stain. The pink bacilli can be seen within a clear capsule. |
 |
| This is a demonstration of endospore formation of Bacillus anthracias. The solid pink cells are vegetative bacteria. The ones that appear green are endospores. |
| This
is alternative spore stain. The dye that stained the spores has faded
in this old slide. The solid red bacilli are vegetative cells
The "bubble-like" cells contain endospores. |
