Isolation and Identification of Staphylococcus aureus and epidermidis Wendy Heck Bio 175: General Microbiology Fall 2012-11-21 Staphylococcus aureus is the most pathogenic for humans and Staphylococcus epidermidis is part of the normal flora and is of low pathogenicity. Staphylococcus epidermidis and Staphylococcus aureus are two medically important species of bacteria. A culture from the nose and throat was taken to perform whether or not Staphylococcus epidermidis or Staphylococcus aureus

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

glucose of 110 mg/dL‚ serum total protein of 6.0 g/dL and lactate dehydrogenase (LDH) of 300 U/L. A diagnostic thoracentesis is performed‚ removing 50mL of pleural fluid. The pleural fluid will be sent for cell count‚ gram stain‚ culture‚ pH‚ glucose‚ protein and LDH. Gram stain and culture of a sputum specimen is negative for tuberculosis. If the effusion is due to the patient’s history of cirrhosis‚ which of the following would be most consistent with this patient’s condition? A. Pleural pH

bacterium was handed out by the lab instructor. The methods that have been learned so far in identifying bacteria were applied to this unknown. Procedures were followed as stated in the lab manual and biochemical test handouts. The first procedure that was done was a gram stain followed by a streak of the unknown on a TSA plate in order to determine the gram reaction and observe the colony morphology. After that‚ specific biochemical tests were performed for gram positive‚ since unknown number

Lalin Candium Lab Report Chemistry Block H Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes Objective: In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment‚ it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due
