Gram staining
A drop of distilled water was placed on a
grease free glass slide and a colony in the nutrient Agar
plate was picked with a heated wire loop after allowing
it to cool and emulsified to make a desirable smear. The
glass was passed over a burning flame for three times to
heat fix. The smear was flooded with crystal violet and
allowed for 60sec, it was then rinsed with distilled
water. Lugol’s iodine was added to the smear for 60sec
and rinsed with distilled water. It was then decolorized
with acetone and rinsed immediately with distilled
water. The smear was counterstained with safranin for
1-2 minutes and rinsed with distilled water. The smear
was then allowed to air dry after which oil immersion
was added and viewed under a microscope using x100
objectives lens [3].
