MIC Practical Report Kerry Haarhoff 18 April 2012 3150540 Introduction Bacteria and fungi are both micro-organisms‚ however‚ fungi are spore-producing organisms whereas bacteria are not and fungi can be multicellular and bacteria is only a unicellular organism. These 2 micro-organisms‚ along with many other things circulate in the air within our environment. These micro-organisms then settle and become more prevalent in different areas. An experiment was conducted to see where

Disinfection‚ decontamination‚ disinfectant‚ antiseptic‚ sanitizer and antibiotic are another chemical agents that can used to affect on bacterial growth. Chemical methods involve the application of specific chemical agents which inhibit growth or kill microbes on the surface of skin. The determineing of an suitable

A dependent variable is the factor in which is being measured and observed. In this case‚ the zone of inhibition was measured which was used to determine the area and percentage of the bacteria growth. Constant variables are the factors in which are kept constant to increase accuracy and ensure fairness of the experiment. If the specific

Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

Bacterial Evolution In the late 19th century‚ diseases led researchers to find treatments to kill the growth of microbes. The outcome of the search was a new kind of medicine which is known as antibiotics. Antibiotics is a variety of substances that control the growth or kill bacteria. Since bacteria is evolving rapidly and resisting antibiotics due to the overuse of the medicine‚ reducing the need and use would help slow down the bacteria from evolving. There are many things that can be done

Bacterial diseases: Introduction Bacterial diseases include any type of illness or disease caused by bacteria‚ a type of microbe. Microbes are tiny organisms that cannot be seen without a microscope and include viruses‚ fungi‚ and some parasites as well as bacteria. The vast majority of bacteria do not cause disease‚ and many bacteria are actually helpful and even necessary to good health. Millions of bacteria normally live on the skin and in the intestines and can also be found on the genitalia

The disease I’ve chosen to write my research paper on is Bacterial Vaginosis. Bacterial Vaginosis is vaginal condition that can produce vaginal discharge and results from an overgrowth of normal bacteria in the vagina. In the past‚ the condition was called Gardnerella vaginitis‚ after the bacteria that was believed to have caused the condition. However‚ the newer name‚ Bacterial Vaginosis‚ reflects the fact that there are a number of species of bacteria that naturally live in the vaginal area and

If bacterial meningitis is suspected several tests sound be done before beginning treatment. A blood sample should be taken and a complete blood count (CBC) should be performed and a lumbar puncture should also be performed as soon as possible. Laboratory findings The white blood cell count (WBC) should be 5‚000-10‚000 /mm3. Critical values associated WBC are 30‚000 /mm3. Variables that may increase white blood cell count include: Physical activity and stress‚ final months of pregnancy and/or labor
