Methicillin-Resistant Staphylococcus aureus (MRSA) To understand Methicillin-Resistant Staphylococcus aureus‚ we must first understand Staphylococcus aureus. Staphylococcus aureus is a spherical‚ or coccus‚ bacteria (MRSA). The bacteria usually appears is chains‚ bunches‚ or grape like clusters‚ (Gregory‚ 229). It is a gram-positive aerobic organism that causes skin infections and sometimes pneumonia‚ endocarditis and osteomyelitis (Beers‚ 1442). This infection commonly leads to abscess formations

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

Each sample was independently examined towards antibacterial activity using two types of micro-organisms (Escherichia coli AATCC 2666 gram negative (ve) and Staphylococcus aureus AATCC 6538 gram positive (+ve)). The result was taken after 4 hours‚ 8 hours and after 24 hours. 2.4. Physico mechanical measurments: 2.4.1. Tensile strength and elongation: The tensile strength and elongation of treated fabrics were measured

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

This project’s purpose is to find the effects of UV light on Staphylococcus epidermidis‚ furthermore recognized as staph infection. Staph infection is an infection usually acquired on the skin that can promote fever‚ nausea‚ pain‚ boils‚ and can lead to MRSA‚ which can lead to death. Because there is no cure for staph infection‚ this experiment called for research on clinical trials. A clinical trial was established that used blue light therapy to delay and kill the growth of staph infection. Coincidentally

Introduction Memory is defined as the faculty by which the mind stores and remembers information(Eysenck & keane‚ 2010). Atkinson and Shiffrin (1968) (Cowan‚ Rouder‚ & Stadler‚ 2000)‚ came up with a model of sensory memory which stated not everything we perceive we process. Craik and Tulving (1975) developed an opposing theory in which they proposed the levels of processing theory‚ stating its not the processing but the type of quality of the processing that is performed‚ that determines the retention
