purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows

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

EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for

What Is Microbiology? Microbiology is the study (logy) of very small (micro) living (bio) things. Microbiology is the study of microorganisms. These "bugs" include: bacteria (that’s the Latin plural for bacterium); viruses (that’s the non-Latin plural for virus - virii sounds weird‚ so I don’t say it); and‚ fungi (that’s the Latin plural for fungus - which by now you have guessed‚ or already knew‚ and may not be all that interested to know‚ anyway). Microbiology is actually made up of several

aerogenes ABSTRACT The objective of this report was to identify an unknown microorganism through several differential media tests. Over the course of a couple weeks‚ ten tests were performed. First‚ a gram stain was performed‚ indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next‚ a negative result in the methyl red test indicated that no mixed acid fermentation occurred. The DNase test was performed and

Nowadays mixed marriages have become more and more widespread and common than they were many decades ago. In former time‚ many countries such as Saudi Arabia ‚ Pakistan‚ Egypt and even Germany had strict regulations and restrictions‚ which didn’t allow to get married with a person of another nationality. However‚ these days time has changed and mixed marriages gradually have increased. According to the Associated Press‚ it was estimated 65000 interracial marriages in 1970‚ and then this number has

TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the
