Microbiology is the study of living organisms that are too small to be clearly seen by the unaided eye. The science of Microbiology dates back only to 200 years‚ yet the recent discovery of Mycobacterium tuberculosis DNA in 3000 year old Egyptian mummy reminds us that microbes have been around for much longer. Infact‚ Bacterial ancestors were the first living things to appear on Earth. The First observations: One of the most important discoveries in the history of Microbiology occurred in 1665

known that were mentioned above. First it was the Gram staining procedure used to categorize bacteria in two groups‚ gram positive and gram negative. Gram staining is one of the most useful test used in the clinical setting to identify bacterial colonies due to their broad staining spectrum. (Black‚ 2008‚ pp. 70-71) The basis of the Gram stain is that gram positive bacteria retains the color of the primary dye‚ the crystal violet‚ whereas the gram negative bacteria loses the primary dye once its

Microbiology is the study of microorganisms which must be viewed with the aid of a microscope or electron microscope. The importance of microbiology includes: used in biomedical research‚ creation of medicines‚ environmental applications and new research tools. Disease causing organisms include: protists‚ bacteria‚ viruses and other microorganisms. Bacteria are important for fixing N2 in a usable form for plants. Bacteria and some fungi are important in decomposition and recycling
