| MDR | miltidrug resistant strains |
| Simple Microscope | uses natural light and small convex lenses; handheld lens/ magnifying glass or an eyepiece/ loupe |
| Compound light microscope | Uses a light source, a compounding medium and convex lens ; high resolution up to 1000x |
| Stereo microscope | Provides detailed 3D images of the specimen by reflecting light off the surface of the specimen (dissecting microscope) |
| Scanning Electron microscope (SEM) | uses high powered beam of electrons to interact with the atoms of the sample; creates high resolution image |
| Transmission Electron Microscope (TEM) | uses high powered beam of electrons to pass through thin unstained samples ; produces an image that can be magnified up to 10,000x |
| Simple stains | determine the basic shape and structure of cells using single dye (methylene blue or safranin) |
