Re: anthrax endospore staining

From:Jennifer MacDonald

If you use the Schaeffer-Fulton stain the spores will stain green with the
malachite green and the vegetative cells will stain red with the safranin.
Heat is used to "drive" the stain into the spores.  Bacillus anthracis
(can't find the underline or italics) spores are oval and located in the
center of the bacillis cell.
