Simple bacterial staining technique

Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner.

This video describes how to perform a simple stain. When viewed under a microscope, bacteria are opaque and almost invisible to the naked eye. In order to study their morphology, cells are stained with different dyes.

The simple dye uses a single stain only, which adheres to the cell, giving it colour. The stain used in this experiment was methylene blue.
