     Consider the possible results of an endospore stain.  What does a positive result for the endospore stain indicate about the organism?  What does a negative result for the endospore stain indicate about the organism?  Why is it not necessary to include a negative control for this stain procedure?   
  
  Solution
the endospore stain is a differential stain, it is used to differentiate between bacterial species that has endospores with the ones that do not have it.
2.a : a positive endospore staining result indicates that the organism has endospore and therefore has the ability to make it to survive in the hostile conditions. Since there are only few genus of bacteria that could do so, we could easily figure out which genus our bacteria of interest belongs to.
2.b. a negative endospore staining result means that the organism does not have an endospore and is therefore a non spore producing bacteria.
