Introduction The purpose of this experiment is to see how much bacteria can and will grow in common places in a typical high school. Common places can mean many things‚ including anything from water fountain spouts to computer keyboards. Such objects can hold up to 2‚700‚000 colony forming units per square inch (or CFU/in sq)(NSF). A colony forming unit is the unit used to find an estimate of the number of cells of a bacteria. This unit of measurement is commonly utilized in the subject of microbiology

manipulate the DNA of bacteria?” This is a question that has no definite answer‚ but a limitless amount of controversy. Since DNA is the code within each and every cell that instructs them on how to function and bacteria are rapidly reproducing microbes‚ genetic engineering is something to be considered. In fact‚ Bacteria were the first organisms to be genetically engineered. Modifying or manipulating the DNA of microbes and bacteria should continue to be allowed because it can be used for human benefit

Bacteria Lab Write-Up Jianna Liu P8 Purpose: The purpose of this lab is to find out which substance‚ alcohol‚ antibacterial soap‚ water‚ or hydrogen peroxide‚ is the best at preventing the growth of bacteria. Hypothesis: Antibacterial soap will be the best because soap is a substance that people use to wash their hands because it takes away the germs. Even the name‚ antibacterial soap‚ suggests that it fights off bacteria. Hydrogen peroxide is second because it is used

Exploring the diversity‚ abundance‚ and variability of diatom-associated bacteria in the oligotrophic ocean I. Abstract The ecology of diatoms may be better explained by conceptualizing them as composite organisms consisting of the host cell and its bacterial associates. Our previous investigated diatom-bacterial interactions at the single-cell level found that bacterial assemblages varied substantially even among closely related individual host cells. The bacterial assemblages associated with single

Ergogenic aids are substances or devices that enhance energy production‚ for use for recovery and provide athletes with a competitive advantage. Numerous ergogenic aids claim to enhance sports performance and are used by amateur and professional athletes. Approximately 50 percent of the general population has reported taking some form of dietary supplements‚ while 76 to 100 percent of athletes in some sports are reported to use them. Physicians can evaluate these products by examining four factors

Patient Hygiene The aim of this assignment is to explain a nurse’s role in relation to assisting patient’s with meeting their hygiene needs. In order to accomplish this‚ the following areas of the subject will be highlighted; why hygiene is so important and the various aspects of hygiene such as; what influences hygiene‚ assessing a patient‚ bed bathing‚ oral hygiene and eye care. Oxford dictionary describes hygiene as “the conditions or practices conductive to maintaining health and preventing

Breathing Aids Paper Bag – used when hyperventilating or when having a panic attack. When hyperventilating the person gets rid of too much carbon dioxide from the blood and takes in too much oxygen causing them to find it difficult to breathe. Breathing into a paper bag helps them hypoventilate to the point where they are calmed and can breathe at a normal rate again. This is because you exhale 17% oxygen‚ 4% carbon dioxide and 89% nitrogen so rebreathing this air will help you inhale more carbon

The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and‚ through a series of metabolic tests‚ identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45‚ henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment. From the streak plate‚ several slides were made to determine the morphology of unknown 45. A Gram stain

such as Bacteria‚ Virus and Fungus. Both the scientific name and common name for Actinomycosis is Actinomycosis. The pathogens that cause Actinomycosis are from a species of Actinomyces‚ most commonly known as Actinomyces Israelii and Actinomyces Gerencseriae. The species of Actinomyces are an Actinobacteria class of Bacteria. The pathogens are endogenous‚ meaning the bacteria originate from inside the body‚ making them not liable to be transmitted from person to person. But the infection can occur

his experiment was done to find out if garlic is effective in killing bacteria. This will help us understand the effectiveness of home remedies such as the use of natural herbs (including garlic) for medicinal purposes. Hypothesis Garlic will kill bacteria and prevent its further growth. Background Herbs and spices have traditionally been used in cooking as they add flavor to our food. These herbs and spices have also been known to many cultures for their medicinal properties. The oils that are
