Staphylococcus epidermidis Essays

Nguyen Nguyen Professor Microbiology 1 May 18th, 2016 01MW – Staphylococcus Epidermidis The Staphylococcus Epidermidis is classified as bacteria. Scientists reckon it to Firmicutes phylum and adjust it in Bacillales order of Bacilli class. This bacteria belongs to Staphylococcaceae family. As the name order, it is settled into Staphylococcus genus and S. Epidermidis species. S. Epidermidis makes its home on human skin, mucosal layer and nasal mucosa. Diseases can be taken form in human body and

Staphylococcus epidermidis is the organism that was identified based on the tests that I had conducted. The tests that I used to identify this organism were the coagulase test and the catalase test. My bacterium was beta hemolytic as well. First, a gram stain had to be done to determine whether the organism was a gram positive organism or a gram negative organism. This determined which set of tests that had to be done. My bacterium turned out to be gram positive. When conducting these tests,

bacteria that was used in my experiment was #8. The possible bacteria inside my petri dish could be any of the following: Bacillus subtilis, Bacillus cereus, Mycobacterium species, Corynebacterium species, Lactobacillus, Staphylococcus aureus, Micrococcus luteus, Staphylococcus epidermidis, Enterococcus faecalis, Streptococcus pyogenes, and Streptococcus pneumoniae Hypothesis I predicted that the bacteria

Today I am going to be talking about Streptococcus agalactiae. The Genus of this Bacteria is Streptococcus and the species is Agalactia. This Bacteria is in Kingdom Monera. Kingdom Monera is full of unicellular organisms with a prokaryotic cell organization, such as bacteria. Streptococcus is a bacteria that goes into humans or animals and causes strep. You are able to have strep in different areas of your body. You can have oral strep or you can have vaginal strep. There are two different types

The first test that gave us an indication that catharant hus ovalis (species Z), is most closely related to Catharanthus roseus (Rosy periwinkle) is test 5 (Test for enzyme M). We found that both species Z and rosy periwinkle have enzyme m present which suggests that share similar enzymes, which helps prove that species Z can produce the same alkaloids. Enzymes are used to increase reaction and help with digestion/ synthesis. Enzyme m, which is present in periwinkle, is used to synthesize the alkaloids

testing for antimicrobial sensitivity of Staphylococcus epidermidis by using the Kirby-Bauer Diffusion test. The three antibiotics utilized in this lab were: gentamicin, novobiocin, and penicillin. I determined the effectiveness of the antibiotic by observing and measuring the zone of inhibition for each antibiotic. I used the measurements and compared them again with the Antibiotic Susceptibility zone chart. I was able to determine whether the S. epidermidis was resistant or sensitive to the different

Vancomycin data were collected by our group. After the incubation period of the diluted tubes containing antibiotic Vancomycin against S. epidermidis, the results were obtained as below, Tubes: 1 2 3 4 5 6 7 8 9 10 (Image 1 indicates the visual growth of S. epidermidis for Vancomycin concentrations 100 mg/ml (tube 1), 50 mg/ml(tube 2), 25 mg/ml(tube 3), 12.5 mg/ml(tube 4), 6.25 mg/ml(tube 5), 3.12 mg/ml(tube

Staphylococcus Aureus belongs to the extremely common bacteria of microflora of the skin and mucous membranes of the humans. These pathogens cause many infections, including superficial and deep purulent infections, poisoning, urinary tract infection etc. In the US, staphylococcus bacteria are supposed to be the leading cause of sepsis, postoperative wound and prosthesis infections. In addition, staphylococcus belongs to one of the leading causes of bacterial food poisoning. Staphylococcus Aureus

Biofilms have become more prevalent in hospitals and adhere to instruments used in medical procedures and even dry objects in hospitals, for example hospital curtains. The bacteria that form these biofilms can be dangerous to humans, for example Staphylococcus aureus, a methicillin-resistant bacteria. [1] Biofilms are a group of microbial cells that are surrounded by a polymeric matrix including proteoglycans, peptidoglycans and polysaccharides located outside the cell that can allow the growth of

Natural Remedies for Fungal Infections and Ringworm Caused by Animals Ringworms are red or dry changes of the skin, which are often itchy and they need to be treated for a long time. These are several tips on how to treat fungal skin infections with natural remedies. What causes ringworm? Scaling, change in color, itchiness and dryness of the skin usually indicate a fungal infection known as ringworm. There are also other fungal infections that have the same symptoms as ringworms. The same

Third Generation Cephalosporin Cephalosporins are antimicrobial drugs that were first discovered in 1945 by Giuseppe Brotzu. Brotzu was a University of Cagliari professor and a Sardinia government official who worked to eradicate malaria. It was found that cultures of fungi called Cephalosporium acremonium, which came from sewage water, could inhibit the growth of other bacteria. Since then, many cephalosporin drugs have been formulated, among them the third generation cephalosporin, which has a

Abstract Background: Methicillin-resistant Staphylococcus aureus (MRSA) remains a major cause of nosocomial infections worldwide. This study aimed to explore the molecular evidence for MRSA transmission between staff and hospitalized patients in the critical care units of university hospital. Material and methods: Nasal swabs were collected from 133 and 120 personnel and patients in اسم یونیتها؟high risk units such as …, respectively. All presumptive MRSA colonies were confirmed based on conventional

Tinea Versicolor Pictures Tinea versicolor is a type of fungal skin infection that affects many people. Here we offer some information, including some Tinea versicolor pictures to help you recognize and deal with this common condition. Part 1: What Is Tinea Versicolor? Tinea versicolor (also called pityriasis versicolor) is a common fungal skin infection that disrupts the normal coloration of the skin, resulting in the appearance of small patches. These discolored areas may also be itchy and flaky

Review of literature Pyogenic brain abscess: Introduction: A brain abscess is defined as a focal sup¬purative infection of the brain parenchyma comprising of immune cells, pus and other materials of the brain. It may be bacterial or pyogenic, fungal or parasitic. Pyogenic brain abscess are the most frequently encountered in the clinical practice (1). It is one of the most serious and potentially a life threatening condition. In the developing countries, incidence of brain abscess is approximately

According to Tietjen 2008, microorganisms are the causative agents of infection. They include bacteria, viruses, fungi, and parasites. In the context of infection prevention, bacteria can be further divided into three categories: vegetative (e.g., staphylococcus), mycobacteria (e.g., tuberculosis), and endospores (e.g., tetanus), which are the most difficult to kill. He also added that asepsis or aseptic technique is a general term used to describe the combination of efforts made to prevent entry of microorganisms

Perceptions of Nursing Students at De La Salle Lipa about Public Health Care in the Philippines Introduction Amid the Spanish regime (1591-1898) brother Juan Clemente began Public Health administration through a dispensary in Intramuros in year 1577. In this administration, water sanitation began, little pox immunization was likewise presented and the making of position of region, commonplace additionally national health office happened

The complete or partial separation of the nail plate separated from the nail bed is onycholysis, which due to trauma, psoriasis, over use of nail cosmetics, or a fungus skin condition. The space underneath the nail causes it to appear yellow or white. Depending on the condition, moderate or severe, you may just need to trim the nail, or ask a doctor about a treatment. Description The white tip of the nail will begin to extend toward the cuticle. The nail may have an irregular border, and discoloration

Tn 4351 was originally isolated from bacteroides fragilis [30] . The transposon was successfully introduced into Cytophaga succinicans, Flavobacterium meningosepticum, Flexibacter canadiansis, Flexibacter strain SFI and Sporocytophaga myxococcoides by conjugation [25]. Tn 4351carries two antibiotic resistance gene. One of the codes for resistance to erythromycin and clindamycin which is expressed in bactroides but not in E.Coli. The other gene codes for resistance in tetracycline and is expressed

Clostridia difficule (C. diff) is a problematic microbe because its has two key virulence factors, toxin A and toxin B. Toxin A is an enterotoxin, which can cause copious water, potassium, and bicarbonate losses. On the other hand, toxin B is a cytotoxin, which can cause damage to the cells. These toxins can be both asymptomatic or cause pseudomembranous colitis in an individual. C. diff is also an anaerobe gram-positive bacterium, which means that it can thrive in environments without oxygen. This

The bacteria, Pseudomonas Aeruginosa, is gram- negative. This means it is does not have a violet stain. It is also considered a bacillus bacteria. Pseudomonas aeruginosa can be strictly found in aerosols, this means it is compressed in pressure and released into a fine spray. Research has been made and found that this bacterium harms a lot of plants, animals, but mainly humans in such case. In some cases, researchers that are researching this bacterium have noted that it might be airborne, but no
