Amber McMillian May 26‚ 2009 Bacterial Vaginosis This is a vagina condition also referred to as Gardnerella Vaginitis that can produce vaginal discharge that is a result from an overgrowth of normal bacteria. This will cause a woman to have a vaginal discharge with a foul odor. It is not dangerous but it can cause bad symptoms. If any woman has this problem they should also be checked for more serious infections such as Chlamydia and Gonorrhea. The normal symptoms are excessive vagina discharge

Pillay‚ Esmerelda (209504371) School of Biochemistry‚ Genetics and Microbiology Department of Microbiology University of Kwa-zulu Natal 25 October 2010 ABSTRACT Different types of bacteria in various forms are found all around us‚ and it is a microbiologist’s job to be able to identify these bacteria. Using various staining techniques and physiological tests‚ an isolated bacterium can be identified. In this experiment‚ a single bacterial colony was isolated form Mycorrhizal spores‚ and further

is researching a newly-discovered species of bacteria. At time t = 0 hours‚ he puts one hundred bacteria into what he has determined to be a favorable growth medium. Six hours later‚ he measures 450 bacteria. a. Assuming exponential growth‚ what is the growth constant "k" for the bacteria? (Round k to two decimal places.) b. After 10 hours‚ how many bacteria will there be? c. When will there be 10‚000 bacteria? 10. A certain type of bacteria‚ given a favorable growth medium‚ doubles in

(Please refer to our web page on Handling Email’s File Attachments for details.) What can Viruses do? ■ Slow down email. Viruses that spread by email‚ such asSobig‚ can generate so much email traffic that servers slow down or crash. Even if this doesn’t happen‚ companies may react to the risk by shutting down servers anyway. ■ Steal confidential data. The Bugbear-D worm

Introduction Although bacteria is microscopic in size‚ it is largely important in the healthcare field‚ environmental work‚ food preparation‚ as well as many other industries. In particular‚ it is essential that healthcare workers be able to identify the species of bacteria invading a human reservoir in order to prescribe the correct antibiotic that will kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However

Isolation of Bacteria in our Physical Environment Introduction: The purpose of the lab is to apply what has been learned so far in Microbiology‚ and use it to collect and examine microbial species from the physical environment. The physical environment around the lab will be utilized to find out the variety of different microbial species growing in and around the lab. This investigation will help in preparation for the individual projects that will be done at the end of the semester. Materials

Antibiotic Resistant Bacteria A better understanding of the use of antibiotics would help prevent the reality of antibiotic resistant bacteria evolving to the point of human extinction. Antibiotic resistance is a natural process‚ stronger bacteria survive and multiply. Even though antibiotic resistance is a natural process‚ it happens faster when antibiotics are used irresponsibly. Through use of media‚ personal responsibility and research‚ our species could help deter further antibiotic resistance

Should Viruses Be Considered “The Walking Dead”? Viruses are often misunderstood because they are so similar to bacteria‚ yet they aren’t living. This seems impossible. How can something so sinister not be a living thing? Think about the damage viruses do. How they multiply and invade and make us so miserable. Yet viruses should not be considered living because they do not possess the three most important characteristics of life: reproduction‚ homeostasis‚ and metabolism. Viruses cannot multiply

effective in killing bacteria‚ fungus‚ and viruses. Household bleach works quickly and is widely available at a low cost. The disadvantage is could irritates mucous membranes‚ the skin‚ and the airway. It also decomposes under heat or light and reacts readily with other chemicals. Bleach solutions begin to lose its effectiveness after 2 hours. You will need to make a fresh solution for each experiment. The advantage of the 70% alcohol mixtures is capable of killing most bacteria within 5 minutes of
