Lab Write Up Identifying an Unknown Microbe Gregory Howard 10E The isolation I was given two unknown microbes and asked to identify them. The first step was to isolate each microbe. I did this by using the streak method to apply each microbe to an enrichment culture. The enrichment culture provides conditions to enhance growth of a species. Obataining a pure culture makes it easier to identify and study a particular species. The macconkey agar plate which is used to isolate and differentiate

What Types of Bacteria are Found on Gas Pump Handles? BY: ANNIE LYONS Problem/Question: How much bacteria are on gas pump handles? Do the newer gas stations have less germs than the older ones? Do we need to sanitize our hands after we pump gas? Hypothesis: Gas pump handles contain bacteria that could cause harmful diseases. There will be a significant amount of staph bacteria on the handles. Control: Each gas pump handle will have

organisms need iron to survive. All except one - Borrelia burgdorferi, the bacteria that causes Lyme disease, has evolved to use manganese instead. For almost all organisms, iron is essential in processes like making new enzymes and other proteins. Perhaps the most obvious example is its role in haemoglobin, the oxygen-transporting protein found in the red blood cells of almost all vertebrates. Researchers knew that the bacteria B. burgdorferi did not need iron, but have now discovered that it requires

Staphylococcus As per wiki encyclopedia Etymologically, Staphylococcus derives from the Greek word “Staphyle” meaning a bunch of grapes, and “kokkos” means berries. Those bacteria under the microscope appear like a branch of grapes or berries. 1. Staphylococcus aureus is the pathogen that causes this infection called staph infections. It resides on the skin, in the mouth, the genital, anus, and at the beginning of the nasal area. They multiply rapidly to form a colony, and they harmlessly

shaped, gram negative bacteria. After much research I have concluded that Victoria is suffering from an outbreak due to the microorganism Vibrio cholerae. “The genus Vibrio consists of Gram-negative straight or curved rods, motile by means of a single polar flagellum” (source 1) which was indicated in Victoria’s stool. In most cases this genus is found in most surface water and grows best in sea water. The disease identified is Cholera which is caused by the bacteria Vibrio cholerae. This

Tonight it is my goal to educate you on MRSA. First, we need to understand what a super bug is or what does this term mean. It does, in reality, sound quite science fiction and quite scary doesn’t it? A “super bug” is defined as a strain of bacteria that is resistant to antibiotics. Now, how many of you are familiar with the term staphyloccus aureus or “staph” for short. All of us have many microorganisms that live in harmony on our skin and for the most part, we don’t even know they are there
