performed within a certain time frame the specimen will become contaminated. Part II: Bacterial Anatomy The purpose of this experiment is to become familiar and gain an understanding of how morphology and the arrangement of bacteria relate to staining techniques. Sample 1 In this study a female patient who had a problem that had arisen suddenly after lunch‚ had allergic reaction to something that she ate or drank had sent her to the bathroom with cramps and copious diarrhea. She knew she

Since it was gram positive‚ I knew my organism had a thick peptidoglycan and no outer membrane. After finding out my organism B was gram positive‚ I did the catalase test on it. After adding the two drops of H202 and seeing bubbles‚ I ruled out Streptococcus lactis. My organism did have the catalase enzyme; meaning it was either Bacillus subtilis or Staphylococcus. To distinguish the two‚ I performed the simmons citrate test

followed‚ they provide accurate data. 2. In 1884‚ Hans Christian Gram described a method of staining bacterial cells while not staining surrounding animal tissues; however‚ he thought the staining method he developed was faulty because not all bacteria stained. In a letter to the editor of the journal in which Gram published his findings‚ write your response to Gram’s concern. 3. Compare and contrast gram-positive and gram-negative cell walls with regard to (a) sensitivity to antimicrobial

Procedures were followed as stated in the lab manual and biochemical test handouts. The first procedure that was done was a gram stain followed by a streak of the unknown on a TSA plate in order to determine the gram reaction and observe the colony morphology. After that‚ specific biochemical tests were performed for gram positive‚ since unknown number five was determined to be gram positive rod. The other tests were performed in this order: Mannitol Salt (MSA) streak‚ Blood Agar streak‚ Catalase test

The very first day of the Unknown project I was acquainted with Denise who was very friendly and was very nice as far as assisting me in the project. The first day we were introduced too various different forms of the unknown such as broth‚ Blood agar plate‚ MSA plate

Microbiology Study Guide Chapters 1-6 Chapter 1 Main Themes of Microbiology Microorganisms Most are not Pathogens Prokaryotic-no nucleus or organelles Very simplistic—like bacteria Eukaryotic-has nucleus and organelles like mitochondria Includes fungus‚ and animals Acellular-not even a complete cell Includes viruses and prions like those that cause Mad Cow disease Six main types of microorganisms Bacterium (prokaryotic) Fungus (eukaryotic) Algae (eukaryotic) Virus (acellular)

antibiotic that works on gram negative bacteria. Gram-negative bacteria are bacteria that do not retain crystal violet dye in the Gram staining protocol whereas Gram-positive bacteria are those that are stained dark blue or violet by Gram staining. The bacteria we used were E-coli that are a gram negative bacteria and the only antibiotic out of Penicillin and Streptomycin that will work is Streptomycin. Penicillin is also effective antibiotic but it will only work on bacteria that Is gram positive because

In March 10‚ the first procedure that was done was gram staining. The purpose of this procedure was to determine if the unknown bacterium is gram-positive or gram-negative‚ and also to determine the cell shape. Gram-positive cells will be purple while gram-negative cells will be pink. The methods for the Gram staining method first starts with a fixed smear of the bacterium‚ covered it with crystal violet for 30 seconds. Afterwards‚ it should be gently rinsed off with distilled water and be covered
