Alexander Fleming Biography… Fleming was born on 6 August 1881 at Lochfield a farm near Darvel in East Ayrshire Scotland. After the war Fleming actively searched for anti-bacterial agents‚ having witnessed the death of many soldiers from septicemia resulting from infected wounds. Unfortunately antiseptics killed the patients’ immunological defences more effectively than they killed the invading bacteria. In an article he submitted for the medical journal The Lancet during World War I‚ Fleming described

Introduction: Attention getter: The most deadly killers on this earth are too small to see with the naked eye. These microscopic predators are viruses. Some viruses have no cure or not even a simple treatment. The unfortunate ones lay on their deathbed‚ crying out for mercy or pray for a miracle to happen. Their bodies slowly deteriorate and eventually die. The Ebola Virus is held responsible for the lives of thousands of people. Audience motivation: The Ebola virus is the T-Rex of microbes. I

LAB 5: Coliform bacteria in surface waters I. Introduction Many organisms‚ including humans‚ have symbiotic bacteria in their guts that aid digestion. Symbiosis is an intimate relationship between different organisms in which both the host organism‚ e.g. the human‚ and the symbiote‚ e.g. bacteria‚ benefit from each other. In this case‚ the bacterium gets a favorable environment and food source in the intestines of a human. In return‚ these bacteria improve the digestibility of food through

The movie Contagion was a wakeup call in many aspects regarding how the possible spread of a deadly disease can play out around the world. Although the virus called MEV1 in the movie was fictional‚ the actual content behind the virus was based on events that have occurred. In fact‚ the movie’s fictional pandemic virus‚ MEV-1‚ is based on the very real Nipah virus‚ according to W. Ian Lipkin‚ an epidemiologist and virologist at Columbia University. The Nipah virus suddenly and surprisingly jumped

Unit 22 1.1 Bacteria are a single cell micro-organism that can only be seen from under a microscope. It lives off the nutrients from its surroundings. Viruses are disease producing agents far smaller than bacteria‚ They are enclosed in a protein coating which makes them more difficult to destroy. The basic unit of Fungi is a hypha which is a hollow tube. The hypha threads spread out over and into the food material making a visible mesh or mycelium. Some fungi form together to create toadstools

A ringworm is an itchy‚ contagious infection caused by a number of fungi‚ affecting the skin or scalp. One could get the infection from skin to skin contact‚ such as handshakes or hugs. One could also get it from touching a contaminated animal or object‚ such as dogs or a doorknob. The most common locations to find ringworms are the scalp‚ chest‚ hands‚ groin‚ and feet. There are many types of ringworms but here are some common ones: tinea corporis (skin)‚ tinea capitis (scalp)‚ tinea pedis (feet)
