Introduction The development of dyes to stain microorganisms was a significant advance in microbiology. Stains serve purposes such as it differentiate microorganisms from their surrounding environment and it allows detailed observation of microbial structures at high magnification.

Microorganisms and other foreign substances are filtered from lymph by lymph nodes and from blood by the spleen. In addition‚ lymphocytes and other cells are capable of destroying microorganisms and other foreign substances.

By utilizing the Kirby-Bauer method‚ researchers and clinicians are able to determine the susceptibility of given microorganisms to different antibiotics and antimicrobials. While antibiotics specifically target bacteria‚ antimicrobials cast a wide net‚ nonspecifically targeting microorganisms and viruses. During this lab‚ we tested the effects of both antimicrobials and antibiotics on different bacterial cultures. By creating different lawns of bacteria

Robert Koch had been interested in studying anthrax and later went on to other diseases. He had found some sticks inside of the animals dead from anthrax and wanted to prove that the sticks he had found grew. Therefore‚ he took pieces of silver and dropped them into the blood of the sheep dead from anthrax so that he could place a piece into the body of a mouse. The next morning‚ the mouse was dead and on the inside‚ Koch dad located the sticks‚ proving that they grew and were the cause of anthrax

Although‚ the function of a cornea is to protect from harmful microorganisms‚ it is also vulnerable to those same unicellular organisms. One of the major diseases affecting the cornea is a corneal ulcer. A corneal ulcer is an "non-penetrating erosion‚ or open sore in the outer layer of the cornea‚ the transparent area at the front of the eyeball" (Medlineplus). Corneal Ulcer has many different names‚ depending on the microorganism that causes the ulcer. Some of the major diseases include Bacterial
