Bacterial Spore Stain

 

Principle:

Bacterial spores are the resting state of bacteria. They can resist various physical and chemical factors and endure execrable conditions. Spores, which have strong refraction, can be observed under light microscope when properly stained. Baso Spore Stain is a very useful tool for bacteria differentiation that allows the identification of size, shape and location of bacterial spores.
