Afton wicks MicroBiology Exam 1 November 8, 2014 Question #1 Bassi and Pasture proved that disease came from microorganisms. Koch’s Postulates specifically isolate the bacteria that cause the disease. Per Koch the pathogen must be present in every case of the disease, it must be isolated from the Patient and must grow a pure culture, Koch was the first to do this. The bacteria from the pure culture must then cause the same disease in a laboratory animal, it is proven that the disease is caused

Phuong Nguyen Professor H. Valtierra Microbiology-Lab 152 4 December 2012 Unknown Lab Report There are many reasons for doing this unknown exercise report. This unknown lab exercise is applicable to real life situation. The reasons range from medical purposes, such as identifying and characterizing what microorganisms is causing the disease in a patient. Furthermore, treating the patient with the correct medications is another important factor. To identify an unknown bacterium, the lab exercise was

MLT1 Experiment 5/Task 6 Differential Staining There are many different ways to stain bacteria for viewing under a microscope. For the most part these are categorized as “either simple, nonspecific or differential (specific) (LabPaq, p.128). The most common staining method used is Gram staining. Gram staining is a differential or specific method of staining. Gram staining is a way to tell the difference between gram positive and gram negative bacteria. The cell wall of the

thinking this was not an ethical decision to make. I decided to speak to my supervisor about this, and after being waived off I made another more serious decision. Similar to psychology’s Institutional Review Board (IRB) and APA guidelines, microbiology has guidelines to follow as well. In this state, the Illinois Department of Public Health (IDPH) is the source of the rules and regulations to follow. I, along with my lead microbiologist who also disagreed with our supervisor, called the IDPH

Staining Microorganisms Microorganisms are often first observed by coloring the specimen with a dye to emphasize the structures for examination. In order to dye, (or stain ) the specimen, it is fixed, (attached to the microscope slide). ( Tortara, Funke, Case, 2013). To carry through this staining and fixing, the microorganisms are killed and attached to the slide. There are several staining techniques to accomplish this preparation. There are simple stains, differential stains, and special

Blood pressure cuffs: friend or foe? Walker N, Gupta R, Cheesbrough J. Source Department of Microbiology, Lancashire Teaching Hospitals NHS Foundation Trust, Preston, UK. nwalker@doctors.org.uk Abstract A study to assess the level of bacterial contamination of blood pressure cuffs in use on hospital wards was performed. Viable organisms were recovered from all the 24 cuffs sampled at a density of between 1000 and >25 000 colony-forming units/100 cm2. Potential pathogens were isolated from

TASK2 EXPERIMENT 3; ASEPTIC TECHNIQUE AND CULTURING MICROBES: Upon completion of the lab, write a brief essay (suggested length of 1-2 pc in which you; ⦁ A. Describe the difference between an obligate and facultative aerobe. Obligate aerobes are organisms that grow only in the presence of oxygen while facultative anaerobes are organisms that grows with or without oxygen, but generally grow better with oxygen. Also, obligate aerobes obtains energy from aerobic respiration while facultative aerobes
