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

substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and antivirals.(1) For a long period of time‚ plants have been a valuable source of natural

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

Blood Components Normally‚ 7-8% of human body weight is from blood. In adults‚ this amounts to 4.5-6 quarts of blood. This essential fluid carries out the critical functions of transporting oxygen and nutrients to our cells and getting rid of carbon dioxide‚ ammonia‚ and other waste products. In addition‚ it plays a vital role in our immune system and in maintaining a relatively constant body temperature. Blood is a highly specialized tissue composed of more than 4‚000 different kinds of

research scientist with a profitable side practice treating the syphilis infections of prominent London artists‚ was pursuing his pet theory--that his own nasal mucus had antibacterial effects--when he left a culture plate smeared with Staphylococcus bacteria on his lab bench while he went on a two-week holiday. When he returned‚ he noticed a clear halo surrounding the yellow-green growth of a mold that had accidentally contaminated the plate. Unknown to him‚ a spore of a rare variant called Penicillium

Blood Cells Leukocytes (WBC’s) Leukocytes also known as white blood cells (WBCs) are cells which play a defensive roll in the body against injury and infection. They migrate towards tissues where they are needed and become functional performing various activities. WBCs can be divided into 2 groups: Polymorphonuclear granulocytes and mononuclear agranulocytes. Both types are spherical while suspended in blood plasma but when they invade tissues after leaving the blood vessels they become amoeboid

Observing a group allows for one to identify the behaviors and relationships of participating members. Every movement‚ response‚ verbal and nonverbal communication is taken into account for to distinguish how each member feels about certain topics and discussions. When observing a primary group‚ the observer is dealing with an abundant amount of personal and shared relationships among the members. These members are involved in this group to merely socialize‚ there is no common threshold for the members

toxin develop progressive paralysis that is fatal 60% of the time if left untreated. But if a patient receives treatment in time‚ the likelihood of death falls to less than 5%. Unfortunately‚ the current standard blood test for detecting the botulinum toxin in adults is slow—and gruesome. Blood from the patient is injected into mice; if the rodents develop symptoms of botulism and die‚ the test is positive. But it can take as long as four days to get results from the mouse test‚ which limits its usefulness
