4. Bacterial Smears and Simple Stains Introduction The refractive index of most bacteria is only slightly greater than that of water; therefore bacteria are difficult to see in liquid suspension because they are almost transparent. To visualize bacteria, stains are used. Bacteria usually carry a negative charge (-).
