What is the difference between Gram Negative and Gram Positive Bacteria?
If you remember, Gram Negative Bacteria will be present, when dyed (Gram Tecnique), will present the color Red and Gram Positive the color Purple. This is due to the composition of the cell walls. Imagine you have two sandwiches one thicker than the other! The slimmer on is composed only of bread, mayonnaise, cheese and ham. The second one has the same ingredients but added tomatoes, lettuce and avocado! Now the lettuce, compared to the bacteria, would be what we know as Peptoglycan. What This does is creates a complex along side Iodine, that is stains the cell wall of the Gram positive bacteria but not the Gram Negative Bacteria since this last one has a very thin layers of peptoglycan.
