Tests are therefore conducted to examine if there is a presence of S. aureus that caused the illness and if the bacteria is or can be recognised as a potential source for food poisoning (Bennet & Lancette, 2001). One such test is known under the name of Direct Plate Count Method as it was illustrated by Bennet and Lancette, generally requiring a step-by-step procedure involving a. Equipment and materials, B. Media and reagents, C. Preparation of sample, D. Isolation and enumeration of S. aureus, E. coagulase test, F. Ancillary tests, and G. Knowledge of some typical characteristics of species of staphylococci and micrococci (Bennet & Lancette, 2001).
After considering several mediums for growing Staphylococcus, it seems Tryptic Soy Agar (TSA) is of some convenience as it allows for the cultivation of a wide variety of microorganisms. Also, the nutritional composition favours plate counting which is beneficial in the...
Afterwards it is an issue of people having to take antibiotics only when necessary. Of course, these are preventive measures that generally are required from individuals. Overcoming antibiotic resistance has taken a new approach as exemplified by Levy (2002) and it consists of trasferring the resistance genes into other bacteria through several genetic means (p. 26). Of the three adoptive methods, it seems the latter, that of DNA released of dead bacteria and incorporated into new strains has also proved efficient in resisting among pneumococci and Haemophilus spp. (Levy, 2002, p. 26)
For determining antibiotic resistance a few sensitive testing methods exist: dilution methods, disk diffusion method, E-test, automated antimicrobial susceptibility testing systems, mechanism-specific tests, and genotypic
After considering several mediums for growing Staphylococcus, it seems Tryptic Soy Agar (TSA) is of some convenience as it allows for the cultivation of a wide variety of microorganisms. Also, the nutritional composition favours plate counting which is beneficial in the examination of food.
In cases of antibiotic resistance, the issue is first and perhaps foremost of hygiene. Afterwards it is an issue of people having to take antibiotics only when necessary. Of course, these are preventive measures that generally are required from individuals. Overcoming antibiotic resistance has taken a new approach as exemplified by Levy (2002) and it consists of trasferring the resistance genes into other bacteria through several genetic means (p. 26).

infection trajectory Methicillin-resistant Staphylococcus aureus (MRSA). The paper introduces the development of the bacterium in its most common iterations. The nature of the infection including symptoms, treatment options which are limited, and efforts from the health community are evaluated. Of particular importance is the portion concerning the differences between the communities-based version and the nosocomial version. Introduction of Evolutionary History of MRSA Nature of Infection Diagnosis, Symptoms & Progression of an MRSA
Lyme Disease and Methicillin-Resistant Staphylococcus Aureus (MRSA) Introduction This text will concern itself with Lyme disease and methicillin-resistant staphylococcus aureus (MRSA). In so doing, it will not only give the description and epidemiology of the concerns, but also the etiology and prevention strategies. Further, diagnosis as well as treatment options and prognosis will be highlighted. 1. Lyme Disease Description and Etiology Described as an illness that is often debilitating, Lyme disease, as the Centers for
Biofilm In order to evaluate the validity of the hypothesis "catabolite control of S. epidermidis biofilm formation is indirectly regulated by CcpA-dependent of the TCA cycle," a laboratory study was performed and then documented in the article "CcpA coordinates central metabolism and biofilm formation in Staphylococcus epidermidis." Through their research, the authors of the article ultimately determined that CcpA is in fact a positive effecter of biofilm formation of S. epidermidis,
Microbiology Microbes Microbial metabolism is referred to as the manner in which microbes find their nutrients and energy that makes them live and reproduce. The paper will describe metabolic requirement for Staphylococcus aureus and Clostridium botulinum that provide them with environment that support their growth. The paper also summarizes mechanism of action by which drug inhibits the growth of Pseudomonas aeruginosa. Staphylococcus aureus Staphylococcus aureus is as facultative anaerobic gram-positive cocci that is able
Efficiency of Antibiotic Resistance Gene Transfer Mechanisms Upon Exposure to Triclosan Triclosan has become the latest buzz word in the grocery store. It is being hailed as the ultimate biocide and finds its way into many everyday products such as toothpaste and hand soap. Mass media produced a great amount of hype and convinced the general public that this was necessary to protect them from potentially harmful or even fatal bacteria.
Pathogenic & Nonpathogenic Microorganisms have the capacity of causing severe disease if the conditions are ideal enough to sustain the life of these microbes. As more and more microbes are able to grow, the risk of disease development rises. Although all microorganisms have the capability of producing virulent effects, some are more able to do so than others. Pathogenic microorganisms are strong enough to fight off the natural defenses of the
