Session #1 Lab 1 OBSERVING BACTERIA AND BLOOD D Haynes BIO-218A Microbiology Lab Friday‚ January 17‚ 5:00pm Objective(s): Our objective is to gain knowledge of the functions and operations of the microscope through observation of bacteria and blood slides that are available for this assignment. We are also learning to “see” and observe various bacteria and their shapes as well as live yogurt cultures‚ blood‚ plaque and cheek swab samples and their arrangements. We

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

* Microbiology: Study of microorganisms Most microorganisms are pathogenicFalse The majority of bacteria are harmless True Total number of bacterial species: about 10 million to a billion What is a microorganism? An organism or virus too small to be seen without a microscope. (Smaller than 0.5 mm) Ex: Bacteria‚ Fungi‚ Protozoa‚ Algae‚ and Viruses Microbiom: collection of microbes Human cells vs. Microbial cells = 1:10 Which statement about Michaelangelo is not correct? A.

dissolved oxygen. The dependent variable would be the fish population. 5. What would be your control? Ans: In controlling the dissolved oxygen you can control the fish population. 6. What type of graph would be appropriate for this data set? Why? Ans: There are several graphs that could be used. However‚ it would be better understood from either a line graph or a column graph. This information would not be well suited for a pie chart. 7. Graph the data from the table above.

Principles of modern microbiology‚ 2008‚ p.1). The term microorganisms consist of bacteria‚ archaea‚ fungi‚ and protest‚ which can either be unicellular or multicellular. They first have been studied by Anton van Leeuwenhoek by the use of his own design microscope‚ in 1675. However‚ they have been an attractive source of study for many scientists‚ since they live in all parts of biosphere and are critical to nutrient recycling in ecosystems. Microbes in general are described as one of the most remarkable

experiment is conducted. The benefits of the streaking technique is when a cultures has multiple species they are able to be more easily identified once they have been isolated. This experiment is much like the experiments completed on an agar plate but on one a much larger scale and where techniques can be perfected before the use of agar plates and specimens are used. Because this experiment uses materials that represent those used in the streaking on agar plates the ability to simulate the events that
