respiratory diseases or viral infections and people who have weakened immune systems are at greater risk. Pneumonia bacteria are present in some healthy throats. When body defenses are weakened in some way‚ by illness‚ old age‚ malnutrition‚ general debility or impaired immunity‚ the bacterial can multiply and cause serious damage. Usually‚ when a person’s resistance is lowered‚ bacteria work their way into the lungs and inflame the air sacs. The tissue part of a lobe of the lung‚ an entire lobe‚ or

Identification of Unknown Organic Compound by Melting Point (M.P)‚ Boiling Point (B.P) and Infrared Spectroscopy Methods and Background The main objective of this lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P)‚ boiling point (B.P) and Infrared spectroscopy (I.R). Index of Hydrogen deficiency (IHD) and elemental analysis makes an experiment more efficient in

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

INTRODUCTION The enzyme catalase converts hydrogen peroxide (H2O2) to water and O2. The evolution of O2 causes bubbling. Thus‚ catalase-positive organisms that are mixed into hydrogen peroxide will cause bubbling (catalase-negative organisms will not). This test is good for distinguishing between Gram-positive cocci in chains (catalase negative) versus Gram-positive cocci in clusters (catalase positive). The coagulase test is used to differentiate Staphylococcus aureus from coagulase-negative

It is thought that archaea and bacteria were diverged early in their existence because of all the dissimilarities between the two groups. Both bacteria and archaea are enclosed in cell membranes. Archaea have a single cell membrane that absences a peptidoglycan wall and also their genetic transcription and translation‚ the two main processes in molecular biology do not show the typical bacterial features‚ but are quite similar to those of eukaryotes. Archaea are more related to eukaryotes‚ even though

Clean your surface with disinfectant to sterilise your lab work surface‚ this will prevent contamination but leave the disinfectant to stand up to 4 minutes so it can penetrate the harder capsules of some bacteria. 4. Using a sterile pipette with draw some of your bacteria culture from the bottle making sure you flame the neck of the bottle to keep the procedure sterile. Place what you have withdrawn on to an agar

Sampling of Gram-Positive Bacteria and Antibiotic Resistance Resting We thought it would be interesting to find out the different bacteria that grow on things we use on a daily basis and the level of antibiotic resistance that those bacteria have. We chose to swab the toilet seat in the MATC women’s bathroom and the ATM machine in the commons area on campus. We were certain the ATM would be dirtier than the toilet seat since the bathrooms get cleaned every day. The first step we took in testing
