Staphylococcus

motility test was performed. A gelatin hydrolysis test was performed. A liquid broth agar was cultured to determine if there was use of oxygen. Results After the multitude of tests performed, it was determined that the bacterial unknown was Staphylococcus aureus. The gram stain slide was positive. The morphology and arrangement was grape like cocci clusters. On the glucose fermentation test the bacterial unknown tested positive for acid and negative for gas. The oxidase test was negative.

Staphylococcus epidermidis is a gram- positive bacterium meaning that it is a bacterium that takes up the crystal violet strain when used in the gram strain test. When this tests is being undertaken the bacterium turns a purple colour when looking through a microscope. This is due to the thick peptidoglycan layer in the cell wall, as it retains the strain after being washed in the decolorization stage. However due the thicker peptidoglycan layer staphylococcus is more receptive of antiseptics due

Staphylococcus aureus was first identified by Sir Alexander Ogston in 1880, although Friedrich Julius Rosenbach is credited with giving the bacterium its current name in 1884. Staphylococcus aureus is commonly considered a natural inhabitant among the microfauna that is found on a human’s skin, inside the nostrils, and inside the lower reproductive tracts of healthy women (Kluytmans et al, 1997). Although S. aureus is commonly found on humans, it is known to be pathogenic, causing a range of illnesses

This experiment was conducted to first, determine if Staphylococcus is present in the nose cavity. Staphylococcus is very common in in the nasal cavities and therefor its highly likely that some type of Staphylococcus will be detected. In order to detect the presence of Staphylococcus a nose swab will be taken and incubated at 37.0˚C for 48hrs in a (m-G+C) broth. This broth has a 10% salt concentration and as Staphylococcus is a halophile and requires salt to flourish, the salt concentration in this

Introduction Staphylococcus, also known as staph infection, has been around since the earth has been in existence (Khan, 2017), but there was not an official discovery of what it was until much later. In the year of 1880, a surgeon discovered the bacterial infection on a patient after a surgery (Mandal, 2012). A staph infection is an infection caused by a group of staphylococcus bacteria that can cause many different conditions and diseases. The staphylococcus bacteria is found in the normal flora

The Bacterium Staphylococcus Staphylococcus can be a severely harmful bacterium. It eventually leads to complete removal of sections of flesh. It can be as small as blister and be as sever as gigantic loss of skin. Staphylococcus is a bacterium that causes a more commonly known disease called a staph infection. Staph infections can invade and attack any part of your body, from your skin, eyes and nails to the inner lining of your heart. Symptoms differ, depending on where the infection develops

that discovered Staphylococcus can produce toxins and is the main cause of pus infection in the 1880’s. Later on they found out that aside from producing toxins Staphylococcus(Staph) also affects the skin and organs. Methicillin was first introduced in 1940, and in 1961 Staph had already developed resistance against it. This particular bacteria affects the skin and our organs. There are many questions unanswered but my question is “ To what extent has methicillin caused staphylococcus bacteria to evolve

Section III The genus Staphylococcus A. Natural Habitat 1. Host range Worldwide, Staphylococcus species are notorious as human pathogens and are the focus of comprehensive studies among researchers in the scientific field. More than, 40 different Staphylococcus species cause diseases known to be clinically and economically significant (Lindsay 2008). Public health has become threatened by the antibiotic –resistance strains that passes on from staphylococcus species to humans (Lindsay 2008).

Staphylococcus aureus is a significant bacterial pathogen, able of infecting most of the tissue in the human body (1). These diseases include deep abscesses, endocarditis, and necrotizing pneumonia (3). This pathogen often appears by autoinfection with populations carried on the skin and its ability to infect and constantly evolve makes it both a dangerous and formidable pathogen. The mechanisms whereby bacteria achieve persistence have been a constant field of study. In the case of S. aureus, there

Staphylococcus Aureus is a gram-positive bacterium that is most commonly responsible for causing staph infections. Staphylococcus Aureus is derived from the greek word kokkos which means “bunch of grapes.” This is very a very appropriate name for this bacterium because under a microscope it looks exactly like a bunch of grapes. This bacteria was first discovered in Scotland by Sir Alexander Ogston. It was simply discovered when Ogston was viewing pus from a wound, and noticed a new bacterium. He
