our quest to eradicate disease‚ especially those that have caused so much human suffering such as polio‚ tuberculosis and cancer‚ mankind may have done itself the greatest disservice of all by providing the means for its own demise from the overuse of antibiotics and the persistent reductionist view of nature. Stephen Harrod Buhner creates a pretty strong argument against the view of the earth as machine. After reading the book‚ it becomes difficult to blithely continue to contribute to the destruction

MICROBIOLOGY COURSEWORK The effect of antibiotic concentration on bacterial growth Introduction Null Hypothesis- Increasing the antibiotic concentration has no effect on bacterial growth. Experimental Hypothesis- Increasing the antibiotic concentration decreases bacterial growth. Scientific Theory Bacteria are prokaryotes and can be identified by their shape. Spherical bacteria are called cocci‚ rod shaped bacteria are called bacilli‚ spiral shaped bacteria are called spirilla and

the bacteria in their throats and therefore it can also cause a mild infection in a healthy patient. MRSA is a strain of the S.aureus bacterium that has evolved over the years and therefore has now become resistant to a number of regularly used antibiotics‚ including methicillin‚ penicillin and amoxicillin‚ therefore making it more difficult to treat than other strains of the S.aureus bacterium. The growth of the resistant strains of MRSA has now lead to health authorities and hospitals trying

The term pneumonia is applied to many pulmonary infections which are most often caused by bacteria. Pneumonia caused by Streptococcus pneumoniae is the most common and is referred to as typical pneumonia. Atypical pneumonia is caused by other microorganisms such as fungi‚ protozoa‚ and viruses. The difference between them were discovered in 1883 by Friedlander and Talamon. Streptococcus pneumoniae was first discovered by Pasteur who isolated it from saliva in a person who had rabies in 1881. Depending

[5-7] Antimicrobial peptides are a part of innate immune system of the organisms. It is found among all the classes of organisms from prokaryotes to eukaryotes in their defence system. [7] Due to several incidences of the conventional antibiotics drug resistant pathogens evolving [4‚8‚9]‚ the antimicrobial peptides are being developed as an alternative drug against such microorganisms. The microorganisms are less likely to develop resistance against antimicrobial peptides. The antimicrobial

Cross Infection Definition Cross infection is the physical movement or transfer of harmful bacteria from one person‚ object‚ or place to another‚ or from one part of the body to another (such as touching a staph-infected hand to the eye). When this cross infection occurs in a hospital or long-term care facility it is called a nosocomial infection. Community acquired infections are those contracted anywhere except a hospital or long-term care facility. Description Cross infection accounts for

Toward Sustainable Chemistry Terry Collins* Chemistry has an important role to play in achieving a sustainable civilization on Earth. The present economy remains utterly dependent on a massive inward flow of natural resources that includes vast amounts of nonrenewables. This is followed by a reverse flow of economically spent matter back to the ecosphere. Chemical sustainability problems are determined largely by these economy-ecosphere materials flows (see the figure‚ below)‚ which current

Antibiotic Resistance in Bacteria For about 50 years‚ antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World War II‚ it treated one of the biggest killers during wartime - infected wounds. It was the beginning of the antibiotic era. But just when antibiotics were being mass produced‚ bacteria started to evolve and became resistant to these medicines

Problems with Developing New Antibiotics Since Alexander Fleming discovered penicillin in 1928‚ which is the first antibiotics. The use antibiotics skyrocket‚ a microorganism infection from a small cut that could have killed a person now could be solved in a matter of days. However‚ after this huge medical advancement which plummeted the percentage of death from any type of bacterial infection within the years of 1944 to 1972 the human life expectancy jumped by eight years. That huge difference

Antimicrobial Properties of Plants A plant with antimicrobial properties means that it destroys or inhibits the growth of bacteria and fungi. Aim: our aim was to see weather or not garlic‚ mint and grass contained antimicrobial properties and if they did how effective they were we were trying to see weather the bacteria will grow around the different plants. Control Test: As a control test what we did was‚ we dipped a paper disc into the alcohol solution we used to dissolve the plants; the
