B. cereus 👇
B. cereus was grown on urea agar induce spore formation. The endospore stain was done using malachite green as the primary stain and safranin as counter the stain.
Malachite green was applied to the smear and set over a steaming water bath for 10 min then safranin added for several minutes .
A). Endospore’s stain blue, still in the vegetative cells which stains red (parent cell).
B). The vegetative cell, stains red.
C). Spores that have been released from the vegetative .
