Reply:The Gram Stain divides bacteria into two categories..%26gt;Gram Positive and Gram Negative.


Some antibiotics only kill Gram Positive organisms, and some only kill Gram Negative ones. Some antibiotics kill organisms in both classes, but only a limited number species.


A Gram Stain Test can be done MUCH more quickly than a Culture and Sensitivity. So, armed with a Gram stain, the doctor can start you on a course of an antibiotic DAYS before he knows what organism he is treating, with a reasonable chance of choosing an effective antibiotic. He can then continue or change your antibiotic when he gets the C%26amp;S back days later.
Reply:Gram positive bacteria are causative of certain infections and the fact is true for gram negative ones. Thus the physician will prescribe his treatment accordingly.
