Staphylococcus aureus Nekita S. Barber Fundamentals of Microbiology Kaplan University Staphylococcus aureus is a bacterium that colonizes inside the nose or on the surface of the skin. The bacterium is not a health concern in a healthy person. S. aureus in the most common cause of staph infections. S. aureus is a spherical-shaped bacterium. S.aureus is a gram positive bacterium. It typically grows and divides to form microscopic grape like clusters. (Laberge, 2011) MRSA is a popular

MLT1 TASK 10 A. Selectively toxic drug therapy is highly effective in killing a microorganism but not harming the host. It is only toxic to the bad while preserving the good. Antimicrobials that are selectively toxic are important when targeting a certain microbe in the body thereby causing no toxicity to the other cells in the body. Humans have certain bacteria that are considered good bacteria and therefore treating an infection with a selectively toxic agent would preserve the healthy bacteria

The scientific study of microorganism is known as microbiology. Microorganisms are small living things or organisms that cannot be seen without the use of a microscope. The microorganism can be categorized as eukaryotes for instance plant, animal, protozoa, fungi and they can also be grouped into prokaryotes such as bacteria and archaea. This paper will focus on how to identify an unknown bacterium. Bacteria which is also known as the bacterium is a non-cellular microbe that lacks membrane organelles

One scientific discovery that changed the field of microbiology, sanitation, and disease prevention forever was Carlos Juan Finlay’s discovery that the tropical disease yellow fever was spread by mosquitoes, especially the Aedes aegypti mosquito. Finlay was born in Camagüey, Cuba on December 3, 1833. He had a diverse education, studying in both France and America. During his time, yellow fever was ravaging and decimating the population of tropical areas, including his home country of Cuba. It is

Diagnosis of an Infected Patient We are given a sputum sample from a patient that may be infected with a bacterium from one of the following genera: Bacillus, Escherichia, or Mycoplasma. In order to determine which bacterium is the cause of the infection, we will need to examine the sample under microscopy, as well as stain it. Looking at the sample with a microscope and knowing what the anatomical differences between each genera are is the first step in identifying the bacterium. The first

Education & Earlier Life Gehard Domagk, at the age of 14, started his educational career at Sommerfeld ( Lubsko, Poland) where his father worked as assistant head master. He attended the University of Kiel to study medicine. When World War I (19141918) war broked out, he served the army as a grenadier and a medic. During those times, there is an outbreak of cholera, typhus, diarrheal infections and other infectious disease. (Nobelprize.org, 2014) When the war ended in 1918, Domagk continued his

My pathogen is called Hepachondria appengyenes. The name comes from a microbiology student, Bailey Bladel, who discovered that people often misdiagnose themselves with appendicitis (a bacterial infection) when they truly have a virus that is infecting their appendix. H. appengyenes enters the body through a mucus membrane and needs 250,000 spores or more in order to attach to the cilia and move downwards. When you drink blood from an animal or eat meat that is too raw, then enough spores will be

KLA Listeria monocytogenes: Reham A. Mohammed 154209 University of Tasmania 2013 INTRODUCTION: L. monocytogenes has been a cause of concern for foodborne diseased hence has been isolated from ready-to-eat foods, meats, poultry, dairy products, seafoods, vegetables and from food processing environs. Statistics show that Listeriosis is a modifiable disease in all Australian states and territories. In 2008, there were 0.3 cases per 100,000 populations. This is the same as the 2003–2007
