Name and Course Section: Camile Manradge & Michele McNeill, Section 704Title and Number: Observing Bacteria and Blood - Lab # 1Purpose: The purpose of this experiment is to gain knowledge of the functions and operations of the compound light microscope and an immersion oil lens by observing prepared slides of various bacteria and blood slides. We are also learning to indentify and observe the various shapes and characteristics of bacteria, as well as, yogurt cultures (fresh and prepared) and blood samples under a microscopic view. We will also be able to distinguish between blood cultures and bacteria specimens.Procedure:Exercise 1: Viewing Prepared SlidesThe first step is to assemble the compound light microscope.

The pathogens responsible for gastroenteritis are bacteria, viruses, protozoa, yeast and fungi.
Bacterial gastroenteritis can be caused by ingestion of pathogens or their toxins. 18429 Words 74 PagesBiologyLabPaq / Published by: Hands-On Labs, [email protected] / www.HOLscience.com / Toll Free 866.206.0773A laboratory Manual of Small-Scale Experimentsfor the independent Study ofgeneral Biology50-0053-BK-02LabPaq® is a registered trademark of Hands-On Labs, Inc.

You will try to grow bacteria from yogurt by putting a small amount of yogurt onto agar plates. You will then put the plates into a small chamber that has no oxygen — an anaerobic chamber that you will make from a bowl, a candle, and some Play-Doh®.
Exposure to increased concentrations of GHGs may lead to respiratory illnesses and, over the long term, permanent brain damage due to circulating micro particles inhaled through the respiratory system which then penetrate the blood brain barrier causing neuroinflamation, oxidative stress and damage, and neuronal damage/loss (Bos et al. Physical activity in the presence of emission from internal combustion engines has shown to be. 8025 Words 33 Pagesabsent or diminished. As the disease progresses, definite redness or cyanosis of the part appears when the extremity is in a dependent position.
Color changes may progress to ulceration, and ulceration with gangrene eventually occurs.Segmental limb blood pressures are taken to demonstrate the distal location of the lesions or occlusions. Duplex ultrasonography is to document patency of the proximal vessels and to visualize the extent of distal disease. Contrast angiography is used to identify the diseased.
Title: Observing Bacteria and Blood- Lab #1Purpose: Being able to learn how to correctly use a microscope and the oil immersion lens to be able to see the prepared slides. Also to learn how to prepare my own yogurt and blood slides.Procedure: First, set up the microscope. Clean the ocular lenses and objectives with lens paper. Then pace the prepared e slide on the stage and make adjustments. Turn the rotating nosepiece until the 10x objective is above the ring of light coming through the slide. Move the slide using the X and Y stage knobs until the specimen is within the view.
Adjust the focus by looking into the eyepiece and focusing the specimen with the coarse then fine focus knobs. Adjust diaphragm until there is sufficient light. Base: supports the weight of all of the microscope parts.Define the following microscopy terms:●Focus: Is the image blurry or well-defined? Focus is related to focal length and can be controlled with the focus knobs. The thickness of the cover glass on the specimen slide can also affect the ability to focus the image if it is too thick for the objective lens. The correct thickness is usually written on the side of the objective lens.●Resolution: Resolution is related to the numerical aperture of the objective lens – the higher the numerical aperture, the better the resolution; and the wavelength of light passing through the lens – the shorter the wavelength, the better the resolution.●Contrast: Contrast is related to the illumination system and can be adjusted by changing the intensity of the light and the diaphragm/pinhole aperture.
Chemical stains applied to the specimen can also enhance contrast.B. What is the purpose of immersion oil? Why does it work? Many bacteria cannot be visualized clearly without the use of oil immersion.Exercise 2: Observing Bacteria Cultures in Yogurt QuestionsA.

Once I was finished I had to take the second slide and smear the blood. I had to let the slide dry.
Then I had to prick my finger again and make 3 more slides. Then I had to mix the chemical. 1979 Words 8 PagesMichele McNeill, Section 704Title and Number: Observing Bacteria and Blood - Lab # 1Purpose: The purpose of this experiment is to gain knowledge of the functions and operations of the compound light microscope and an immersion oil lens by observing prepared slides of various bacteria and blood slides.

David MwangiMicrobiologySpring /20143305-04Introduction:The purpose of this lab was to identify an unknown microorganism using lab techniques. The importance of identifying microorganisms is essential to the survival of humans, expansion of modern day medicine and improvement of quality of life. In 1884, Hans Christian Gram designed a differential staining technique to identify bacteria that would change the future of microbiology. 1470 Words 6 Pagesthe study of microorganisms; whether it is bacteria, fungi, algae, protozoan, viruses or archaea (Leboffe & Pierce, 2006). Microbes come in all different structures and classifications. Before the 17th century the idea or microbes existed, but was never proven until a scientist provided something that allowed us to see what the naked eye alone could not see (Pelczar, 2015).It all began when Anton van Leeuwenhoek invented a microscope and began observing objects under it (Boundless, 2015).
