Experiment 2: Microscopy & Simple Staining September 30‚ 2013 General microbiology laboratory The invention of the microscope has opened up a whole new dimension in science. By using microscopes scientists were able to discover the existence of microorganisms‚ study the structure of cells‚ and see the smallest parts of plants‚ animals‚ and fungi. Today‚ the microscope is still a commonly used tool to diagnose illness in hospitals and clinics all over the world (1)

GRAM STAIN THEORY: The most widely used staining procedure in microbiology is the Gram stain‚ discovered by the Danish scientist and physician Hans Christian Joachim Gram in 1884. Gram staining is a differential staining technique that differentiates bacteria into two groups: gram-positives and gram-negatives. The procedure is based on the ability of microorganisms to retain color of the stains used during the gram

The Comparative Analysis of Simple Staining and Gram Staining Techniques by observing E. Coli and S. Pyogenes under the Compound Light Microscope INTRODUCTION: A German bacteriologist‚ Dr. Theodore von Escherich‚ was the first man in 1885 who discovered the bacterium named Escherichia coli‚ which are gram negative and appears in rod shaped. Most kind of bacteria E. Coli does not cause diseases and some strains indeed are beneficial in helping the process of food breaking down in the intestines
