Lindsay Wootton Clinical Microbiology Laboratory 211.2 Task 1 A. This experiment consists of four different activities. They include the fresh wet mount, direct staining using crystal violet and indirect staining using both Congo red, and crystal violet. A close examination of these examples showed that the wet mount slide examples were all the same in appearance. the cheek and yeast both appear to have some circular cells. the cheek smear was the most difficult to see. The direct staining

When I receive a sputum sample from a patient, my first step that I would take would be to prepare the specimen to be viewed under a microscope. Knowing that it would be Bacillus, Escherichia or Mycoplama, I would start ruling them out one by one. I would start with Bacillus. They are rod shaped bacterium which form endospores. Their movement is propelled by flagella. Bacilli are gram positive, but because if forms endospores, I would do the Endospore staining. Endospores are resistant to stain

Throughout the centuries, there have been many scientific discoveries which have played an important role for the betterment of the world. Although there have also been some that have changed the world for the worse. Some are well-known and instantly come to mind when one is asked to name the most important scientific discoveries of all time, but there are other weighty discoveries that are more refined in nature - ones that are easily overlooked, regardless of the tremendous impact they may have

PRINCIPLES OF DISEASE I. TERMINOLOGY * Pathology- the study of disease * Infection- the invasion or colonization of the body by a pathogenic microorganism * Disease- abnormal state of health as the result of an infection * If Pseudo aeruginosa infects the eye it can cause a disease termed Pseudomonas keratitis. The etiologic agent (cause) of this disease is: Microbial pathogenesis- the characteristics/traits the microbe has that leads to the disease. II. NORMAL MICROBIOTA

Sandra L. West Professor Wilson Microbiology 2211 18 June 2018 Botulism Botulism is an illness caused by a toxin produced by Clostridium botulinum bacteria. The bacteria that causes botulism can be naturally present in the environment, usually within the soil. Surprisingly, the bacteria alone do not cause botulism, the bacteria produce spores, this provides a special cover for the bacteria. The spores are what can grow and produce the toxin that causes botulism. Conditions that help spores grow

Role of azithromycin against clinical isolates of family enterobacteriaceae: A comparison of its minimum inhibitory concentration Aim: To determine the effect of Azithromycin, a new azalide antibiotic, on clinical isolates of the family Enterobacteriaaceae and to determine and compare its minimum inhibitory concentration (MIC). Antimicrobial agents are commonly used therapeutically and prophylactically for travelers' diarrhea. Resistance of enteric pathogens to these agents may prevent the success

The infectious patient If you have an infection how do you know from what bacteria is came from. I will discuss the genera Bacillus, Escherichia and Mycoplasma. They have many structural differences that can distinguish them. There are also staining processes that can identify each. Let’s get started. The genera Bacillus is a gram positive rod shaped bacterium. When viewed under a microscope Bacillus can be seen as a single organism or in chains. It forms endospores that are resistant

Fermentation, Good or Bad? The topic that connects all three of these articles together is the current and ongoing research of the uses of microbes in food and for nutrition purposes. Food microbiology is the study of microorganism inhabit, create, or contaminate food. Food microorganisms can be found in a various amount of ways. These microorganisms can be natural or they can be genetically modified organisms. There are also good natural microbes and bad natural microbes that we can find in the
