WebUnder a Gram stain, bacteria changes to one of two sets of colors (pink to red or purple to blue). These are categorized as gram-negative or gram-positive. Haemophilus influenzae is gram-negative coccobacillus that appears red under the microscope. Gram-negative bacteria have a hard outer shell that protects them and makes them harder to kill. WebAlthough it is described as Gram-positive, it is easily decolourized during the staining procedure and may appear Gram-negative. On microscopy, C. diphtheriae exhibits considerable pleomorphism, ranging from the classical club shape to long slender bacilli. The arrangement of organisms on a smear often resembles Chinese letters.
