Staphylococcus aureus

suitable treatment. The scientific context of the the API 20E test is clinically used in quickly identifying enterobacteriaceae bacteria and gram-negative rods. In the Antimicrobial Susceptibility experiment, three microorganisms which were Staphylococcus aureus, Escherichia coli, and the unknown were put into three different agar plate and each plate were divided into four quadrants. In each of the four quadrant of the agar plates the antibiotics of ciprofloxacin, penicillin, Trimethoprim with…

the three possible bacteria were Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecalis. The first biochemical test was to preform the Urea test. A sample of the gram-positive cocci colony was taken out which then was transferred into a Urea broth to test for Urease. This was incubated at 37 degrees Celsius for 48 hours. The ending result was no color change, which was a negative reaction in the Urea broth. The results eliminated Staphylococcus epidermidis from being the…

On October 1, 2008, The Centers for Medicare and Medicaid Services (CMS) implemented a new regulation, which deny payment for selected 10 conditions occurring during the hospital stay and are not present on admission. Out of these 10 hospital-acquired conditions, three of them were healthcare-associated infections, which are a common, expensive, and often preventable. According to an article published in Med Care on 2010, this policy was the first significant step to move output-based inpatient…

Abstract: The objective of these series of experiments was to identify two unknown bacteria’s. Broth culture #20 was selected and subjected to qualitative tests for identification. Gram stain tests were performed in order to identify which unknown is gram positive and gram negative. Using selective and differential media, like MacConkey agar which allows the growth of gram negative bacteria only that are able to ferment lactose. Also, mannitol agar was used which isolates and detects…

glycan chains. As some types of A. aureus (methicillin-resistant S. Aureus) are resistant to β-lactam antibiotics, an antibiotic effective against MRSA may be the optimal treatment. An alternative treatment could be treating the boils with warm and wet washcloth, which will stimulate them draining on its own. 5. S. Aureus is carried by many individuals and can be easily transmitted to the environment by the hands. The nostrils and wet skin are good habitats of S. Aureus. The elderly, diabetics…

Microbiological Control 1. Evaluation of Potentially Hazardous Foods Food is potentially hazardous food if it consists in whole or in part of milk or milk products, eggs, meat, poultry, fish, shellfish, or other ingredients capable of supporting rapid and progressive growth of infectious or toxigenic micro-organisms. Specific recommendations for ensuring the safety of potentially hazardous food are stated along with sanitary practices recommended for the storage, preparation, display, and…

dissolving the compound in DMSO. Antimicrobial activity was tested by the disc-diffusion method under standard conditions using Mueller-Hinton Agar (MHA) and the antibiotics used as listed below, Table 1.As control MTCC K. pneumoniae 7407, MTCC S. aureus 3160 and ATCC E.coliJ53. Antimicrobial disc diffusion susceptibility AST was done by Disc-Diffusion method (Qureshi AH et al., 2004) for all the derivatives at the concentration 1mg/ml to find out the zone of Inhibition. The derivatives of…

severe, and scratching the rash can make it even itchier and cause more inflammation. If the skin barrier breaks, then bacteria, particularly Staphylococcus aureus, can affect the skin, which is the perfect breeding ground for them. It can be quite challenging to break the itch and scratch cycle. What factors aggravate eczema? Typically, the Staphylococcus aureus bacteria affect the skin of people suffering from the eczema skin condition. Once the skin barrier breaks and fluid oozes onto the…

mutations allowing for more variation in the gene pool. However, not all mutations are beneficial, but those which acquire the gene which enables to best survive their surrounding will be favoured by Natural Selection and move on to reproduce. Staphylococcus aureus is one species of microbes which has demonstrated these abilities as they have evolved and adapted to either penicillin, Methicillin or Vancomycin in a short period of time. The process of survive can occur without pressure as…

possible organisms. A MacConkey and Mannitol Salt Agar tests were conducted on the organism and revealed the following. No growth on the MacConkey plate resulting in a gram positive bacteria and the Mannitol Salt Agar result showed it could be Staphylococcus or Micrococcus. (1) A gram stain test was used in determining the shape, size and arrangement of the unknown bacteria (1). The unknown organism is heat fixed onto the slide, in order for the organism to be stained. The two stains, crystal…
