Staphylococcus Research Paper

The Staphylococcus aureus bacteria belongs to the Staphylococcaceae family. It is small, round shaped, and non-motile. Staphylococcus aureus stains gram positive and can often be found in small clusters (Mandal, 2010). It often forms chains and is a large contributor of soft tissue infections. It is of a yellow color, hence the name ?aureus? which comes from the Latin term ?aurum? for gold (Orenstein, n.d.). Staphylococcus aureus is found in a few spots on the human body, such as the nasal passage, the skin, the oral cavity, and even the gastrointestinal tract. Staphylococci and Streptococci are two different strands of the bacteria and are very hard to distinguish from one another. In order to tell the difference between them, without a microscope, a catalase test needs to be performed. The test is undergone by adding 3% hydrogen peroxide to both samples. Since Staphylococci are catalase positive, meaning they produce catalase, they will produce O? while the Streptococci will not because Streptococci are catalase negative (Todar, n.d.).

Methicillin-resistant Staphylococcus aureus, or MRSA, is a bacterium that is resistant to many available high- level beta-lactam antibiotics, which include penicillins, “antistaphylococcal” penicillins and cephalosporins. Staphyloccoci are the most important bacteria that cause disease in humans. MRSA is sometimes branded as a nosocomial infection as it usually plagues patients that are receiving treatment in a hospital. The skin is the most common site of infection, where MRSA can cause cellulitis, folliculitis, or boils in the skin, but can also commonly be found in the nose, underarm, groin, upper respiratory tract, intestine, vagina and rectal areas of the body. MRSA infections occur with there is a break in the skin that allows the Methicillin resistant

The online article discusses the spread of diseases amongst students in close quarters with relation to a recent study on staph infections. General demographics give examples of how a disease such as staph can spread between students rapidly in their limited environment. A specific study on staph resistant to medicine references statistical data that implies real-life scenarios. Powers elaborates on the idea that staph infections on campuses are not a major concern, but a concern nonetheless as long as students live in a communal setting. The author implies at the end of the article that the most precedent concern with staph infections lay in better upkeep of hygiene facilities used by students as students in these environments are completely

Staphylococcus aureus is a specific type of bacteria which is a member of the Staphylococcaceae family (Medical News, 2016). The bacteria is found in clusters (staphylo-) which look like grapes and as a result is called Staphylococcus. Staph is Gram positive (which is a method for identifying bacteria) and is non-moving (Medical News, 2016). It can infect all mammalian species and because it can infect such a broad range of mammals it is easily transmitted from one species to another species. Of special concern is methicillin-resistant staphylococcus aureus (MRSA) which does not respond to antibiotics.

Antibiotics have been E.coli and Staph are two distinct and separate types of bacteria. They each live, thriving in environments wherein they can do substantial damage to their hospitable host! For example, E coli often times lives inside the intestinal track of humans and animals and can disrupt their day to day routines. E coli can be harmful causing gastrointestinal issues like diarrhea and vomiting. Staph, to the contrary, can thrive in a number of places on a living thing, although they typically impede the skin of a living host. Staphs can be aggressive, and in some cases are immune to antibiotics that are typically used to treat the infection. Staphs can be deadly and are usually transferred from actual direct contamination or contact.

Before the turn of the 21st century, physicians across the country were realizing that the possibility of being able to treat and cure virtually any microbial infection with the use of a single or a combination of antimicrobial medications was becoming more and more of a challenge. In the late 1960s and early 1970s, reports of pathogenic resistance to even the most potent antimicrobial medications of the time were being sent to the Centers for Disease Control. Among even the most dangerous pathogens that have developed and are developing drug resistance to one or many antimicrobials, Staphylococcus aureus (S. aureus) is perhaps a case in which the world is most familiar and of the greatest concern within the medical community due to its natural virulence-its ability to cause a multitude of life-threatening infections, and its above average ability to combat and adapt to a vast array of environmental conditions.

Methicillin-resistant Staphylococcus aureus (MRSA) is a harmful and virulent antibiotic resistant bacterium that is a major concern in most American hospitals. Modern scientists are aiming to discover effective prevention methods for MRSA in hospitals, so productive prevention guidelines can be created. Clinical microbiologists such as K. Nguyen, J. Cepeda, and M. Struelens all conducted clinical trials in separate American hospitals. They employed different MRSA inhibition techniques, such as hand hygiene, isolation, and MRSA screenings, which were tested on a wide

Staphylococcus Aureus is a bacteria formed in a group. It is more commonly referred to as staph infections, ( pronounced staff ). Staph infections can be mild to severe in nature, and if left untreated can be fatal. They can be treated with different medications depending on the type of infection. Topical, oral, or intravenous medications can be used. There are many different types of staph infections to include, MRSA (methacillin resistant staphylococcus aureus), pneumonia and cellulitis. This paper will target how staph infections effect adult subjects.

Bacillus cereus is a Gram-positive, facultatively aerobic sporeformer whose cells are large rods and whose spores do not swell the sporangium. These and other characteristics, including biochemical features, are used to differentiate and confirm the presence B. cereus, although these characteristics are shared with B. cereus var. mycoides, B. thuringiensis and B. anthracis. Differentiation of these organisms depends upon determination of motility (most B. cereus are motile), presence of toxin crystals (B. thuringiensis), hemolytic activity (B. cereus and others are beta hemolytic whereas B. anthracis is usually nonhemolytic), and rhizoid growth which is characteristic of B. cereus var. mycoides.

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, such as minor skin infections, pneumonia, toxic shock syndrome, and sepsis (National Institute Of Allergy And Infectious Diseases, 1999). Several other species of bacteria have had their names changed since they were first discovered, such as

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 to the absence of an outer membrane.

Staphylococcus aureus is a type of bacteria. It stains Gram positive and is non-moving small round shaped or non-motile cocci. It is found in grape-like (staphylo-) clusters. is one of the five most common causes of infections after injury or surgery. It affects around 500,000 patients in American hospitals annually. It is abbreviated to “S. aureus” or “Staph aureus” in medical literature. S. aureus was discovered in Aberdeen, Scotland in 1880 by the surgeon Sir Alexander Ogston in pus from surgical abscesses. (Mandal, 2012).

Life History and Characteristics: Staphylococcus aureus is a gram positive bacterium that is usually found in the nasal passages and on the skin of 15 to 40% of healthy humans, but can also survive in a wide variety of locations in the body. This bacterium is spread from person to person or to fomite by direct contact. Colonies of S. aureus appear in pairs, chains, or clusters. S. aureus is not an organism that is contained to one region of the world and is a universal health concern, specifically in the food handling industries.

Staphylococcus aureus is a bacteria that can be found on the nose and other respiratory areas, present in about one-third of the population. ‘Staphylococcus’ comes from Greek language, translating into “cluster of grapes” to describe the spherical berry shape of the bacteria and ‘aureus’ translates to “gold” in Latin. That being said, Staphylococcus aureus is golden in nature. When stained and observed under a microscope, it retains a dark purple color and is known to be Gram-positive bacteria. A staining method is used to examine the different cultures (Gram-positive or Gram-negative) observing its observation of characteristics portraying shape and size.
