1. ‘Gram-negative’ indicates that these microorganisms – because of their cell wall structure – appear pink under the microscope when stained with the method discovered by the Danish scientist Gram. Gram-negative bacteria have a thin cell wall and hence cannot survive well in a dry environment; they are bacteria that live in water and in our gut (Escherichia coli, Klebsiella species, Pseudomonas species are typical examples). Gram-positive bacteria (such as staphylococci and streptococci) have a thick cell wall and are able to survive in dry environment (like the human skin).
