At the beginning of the semester‚ samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and

30 February 2014 Antibiotic Resistant Bacteria: What is it‚ how to prevent it and who it affects? In the United States alone‚ about 23‚000 people die from antibiotic resistant infections yearly. It is also one of the top 15 most dangerous illnesses in the country (United States House of Representatives). Antibiotic resistance is when bacteria develops a different response to an antibiotic that is its ancestor bacteria. Slight changes in bacteria enable the antibiotic to work and successfully

The first test conducted on unknown bacteria 32 was the Gram stain. From this stain‚ unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria‚ Gram-positive rods and Gram-positive spirillium. Next‚ the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green‚ steam‚ and safranin it was found that unknown bacteria 32 did not contain endospores. This eliminated Gram-positive cocci Sporosarcina

some people see bacteria as something that is harmful and that causes nothing but illness and infections. Bacteria can actually be helpful as well. It can provide vitamins to your body‚ help digestion‚ destroy bad organisms‚ help make medicines and also help out with the environment. In this research paper‚ it will describe two bacteria that are helpful and sometimes harmful to humans and the environment‚ which are E. coli and Lactobacillus Acidophilus. E. coli E. coli is the bacteria that live in

Name: Danielle Title: Unknown Lab Report Introduction: There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The

resistance occurs when an antibiotic is no longer effective against a particular bacteria‚ making that organism resistant to the effects of the antibiotic. Bacteria become resistant due to selective pressure. Those organisms which resist the antibiotic‚ and do not die from it ’s effects have a greater chance of survival within the host‚ therefore allowing them to reproduce and spread it ’s resistance to other bacteria. while the ones susceptible to the antibiotics die. This can be caused by unnecessary
