At the beginning of the semester‚ samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and

* 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.

Proteus vulgaris Antibiotic Sensitivity Assay By: David Toelkes BIO 225 June 12‚ 2012 Lab Partners Alexis Blackmon Cheryl Cardiff Megan Dereani Logan Freeman Abstract Development of bacterial resistance to the antimicrobial drugs identified the need to determine a given bacterium’s susceptibility or resistance to a given drug which prompted W. M. M. Kirby and A. W. Bauer to develop a single disk method for susceptibility testing. This experiment used the Kirby-Bauer disk diffusion

BACTERIA. CLASSIFICATION Bacteria are extremely small and some can be just seen with the naked human eye. They are much smaller than eukaryotic cells but are still very complex despite their size. .the cell is surrounded by a cell membrane that enclosees the bacteria cell. They are single celled organisms. Bacteria are prokaryotic cells and therefore do not have a nucleus and do not have a lot of organelles like: mitochondria‚ chloroplasts‚ and other organelles that are usually found in eukaryotic

Bacteria can be distinguished from one another by their morphology (size‚ shape‚ and staining characteristics). In this lab experiment‚ bacterial morphology was examined by observing both stained and unstained organisms. A wet mount is a preparation process where a live specimen in culture fluid is placed on a slide and the organism is free to move about. In the wet mount slides provided via LabPaq software with cheek‚ dental plaque‚ and yeast specimens were observed. The wet mount preparations

Staphylococcus aureus: From a Spot to the Hospital The hospital is silent this morning‚ as the sun breaks through the blinds and casts off all the silver objects in the room. My hospital bed is uncomfortable‚ and it makes me yearn for my 100-year-old mattress and many unnecessary plush-pillows. The smell of bleach and cleanliness lingers in my nose and almost makes me feel sicker. How did I end up here? Well‚ that is not an adrenaline rushed injury or a freak accident‚ but something that started

in the staining methods‚ the cells and their borders were very distinct while the one in the wet mounts were not as distinct. It was a bit challenging to determine the figures in the cheek smear‚ but the bacteria form in the yeast wet mount were easily recognized. The direct staining was the following technique used. The cells were very easy to assess‚ well demarcated and had a very distinctive color. Instead of the background and around the cell in the cheek smear‚ the indirect staining way seemed
