Extract of sample "Staphylococcus"

Download file to see previous pages The different species prove to be dangerous because they show resistance towards methicillin and other potent antibiotics (Acton, 2012, pg.38).
Incidence of a disease is defined as risk of contracting a disease. Hence various studies have been conducted to assess the incidence of methicillin resistant staphylococcus aureus. There was a dramatic increase in the number of methicillin resistant staphylococcus aureus cases in the late 1990s in America. The strain was seen to cause infections in children who were not at risk. The children had not had recent hospitalization, surgery, injection infusion nor had they resided in a medical facility for a long time. Four fatal pediatric cases also emerged between 1996 and 1999. This raised questions. The methicillin resistant staphylococcus aureus could be acquired in the community, and this also suggested that a new strain of the bacterium was present which differed from the already present strain in hospital settings (Song et al, 2013, pg. 69).
The epidemiology of methicillin resistant staphylococcus aureus is continuously changing due to its capability to resist. This trait makes it hard to treat these infections. Hence regular surveillance studies are held to assess the status of disease. Surveillance studies from 1990s indicated an increase in the incidence of MRSA infections. The role of surveillance studies is to lower morbidity, mortality and incidence of disease (Meija et al, 2015, pg. 79). Methicillin resistance is a universal problem but is more prevalent in countries where use of antibiotics is high. American and China have the highest rate of antibiotic consumption and hence face the most cases of methicillin resistance (Tisserand, 2015, pg. 20).
The normal bacterial flora of humans includes S. aureus often. Studies indicate that the organism is present in the nasal colonization of the adult population. Staphylococcus aureus ...Download file to see next pages Read More

The Molecular Mechanism That Make Staphylococcus Aureus Resistant To Antibiotics

... is usually acquired in a sequential manner (Bauman, Machunis-Masuoka, and Tizard, 2004). This is usually well illustrated by a bacterial strain called staphylococcus aureus, which is discussed abundantly in this essay. Resistance may be due to mutation which can either be spontaneous or induced by other factors. It may also be through gaining resistant genes from other resistant bacterial species. This is through horizontal gene transfer which may occur through conjugation, transduction or transformation. These antibiotic resistance genes usually reside on the plasmids expediting their transmission. Contact with antibiotics necessitates natural selection, leading to the survival of organisms with resistant genes. This causes the gene...

Staphylococcus Infection

..., especially near the genital and anal areas, is highly likely to be positive for the presence of staphylococcus aureus. MRS, first identified in 1994 and traced back to pigs ( according to Gonzalez, 2011) is also in this group of bacteria , but is much less prevalent, being present in only 1% of people according to Ostrosky-Zeichner ( 2009) In the case of staphylococcus aureus an American survey found its presence in 29% of the American population in 2003-2004 (Kuehnert et al 2006). Bobak in 2009 came up with a very similar figure of 25%. It is when the bacteria reach other places that problems begin and so it should always be considered as a possible pathogen. Often it enters the body through a break in...

... history of MRSA infection (Crossley et al 272). It is important to differentiate the microbiological characteristics of the MRSA strains from the S. aureus, the disease spectrum and manifestations so that a correct diagnosis and treatment plan can be devised. Fig 1 :Prevalence of MRSA shown in relation to the age of the patients performed by the National Health and Nutrition Examination Survey 2001-2004 (Crossley et al 281). The microbiological characteristics of the staphylococcus aureus are significant in understanding the clinical course of the disease. Staphylococci are included in the Gram positive bacteria which are signified by their catalase-positive and facultative anaerobic properties. Staphylococci measure 0.2-1.5 micro-meters...

Methicillin-resistant Staphylococcus aureus

...tread from the microbiologist perspective and a nightmare to most pharmaceutical companies, who have to perform fresh research to develop new drugs. Staphylococcus aureus and Pseudomonas aeroginosa are is considered the most common pathogens responsible for a wide variety of hospital-acquired infections such as urinary tract infections, respiratory pneumonia, wound infections, bacteraemia, and skin infections. Staphylococcus aureus is a gram-positive bacterium that has its habitat on the human skin without causing any infection; however, injuries on the skin eliminate the protective mechanism leading to infection. The bacterium has been cited to cause acute food poising, toxic shock syndrome, cellulitis,...

... cocci. They are normally arranged in chains that do vary in their lengths and sometimes are ever in pairs. Several species of this genus are able to grow properly on conventional culture media but their growth can be enhanced on culture media with sterile blood (normally horse or sheep) and in an environment that is aerobic or CO2 enhanced environment. Several of these species are able to grow both anaerobically and aerobically hence known as “facultative anaerobes”. Some streptococci species are obligate anaerobes. Hence Catalase negative. Staphylococcus aureus is a Gram positive non-motile cocci bacterium. It is normally in grape-like (staphylo-) clusters, hence the name Staphylococcus. Staphylococcus is among the five most common causes...

... in the blood therefore avoiding the agents of the immune system (Gordon and Lowy, 2008). S. aureus is then transported to other organs where bacterial colonies produce cellular death and damage. 4. What caused the food poisoning in the patrons of Mr T’s restaurant Cream pies from the restaurant were contaminated by S. aureus that came from Mr. T’s infection. Staphylococcus aureus thrives in foods that are either stored at room or refrigerator temperatures. Sometimes, signs of spoilage are not obvious although the bacterial colonies could already be significantly plenty. S. aureus produces a certain toxin called staphylococcal enterotoxin B (SEB) that is heat stable. 5. What are the properties of S. aureus that allow it to cause...

Staphylococcus aureus

... such as enzyme production. Introduction: Staphylococcus aureus are spherical, gram positive non spore forming with 0.5- 1µm long bacteria as viewed under microscope. In 1988, S.aureus was first discovered in Aberdeen by Alexanda Ogston. Determination of Staphylococcus follows an observation in solidified medium such as nutrient agar and selective medium manitolagar. This bacteria is salt tolerant. From the main genus staphylococcus there are 32 species of which 11 are harmful and can be spread causing diseases in human body. The most common of these diseases causing staphylococcus are S.aureus and S.epidermis. Growth rate and survival of Staphylococcus is affected by a number of factors including temperatures, PH, Oxygen and water present...

...resistant Staphylococcus aureus that has led to study of potential medicinal herbs for treatment. Some plants extracts have antimicrobial activity and can be great significance in therapeutic treatment. Strains of Staphylococcus aureus were vulnerable to extracts of Punica granatum and Tabebuia avellanedae, which are Brazillian traditional medicinal herbs. Two naphthoquinones isolated from T. avellanedae and ellagitannins isolated from P. granatum were mixed and they exhibited antibacterial activity against Staphylococcus aureus. These natural occurring naphthoquinones showed a lower minimum inhibitory concentrations than semi-synthetic furanonaphthoquinones (Machado, et al., 2003). Good...
