Sir Alexander Fleming Alexander Fleming is a Scottish biologist and pharmacologist. He was born at Lochfield near Darvel in Ayrshire‚ Scotland on August 6th‚ 1881. In 1999‚ the Times magazine named Fleming one of the 100 Most Important People of the 20th Century for his discovery of penicillin. While penicillin is widely cited as one of the most important discoveries of the 20th century‚ uncertainty over whether or not Alexander Fleming actually discovered it caused many to question his 1945 Nobel

Mold Growth Experiment Bailey Gaudi Introduction Have you ever asked yourself‚ how does mold (Fungi) grow? The world of fungi is so stunning and diverse. You can see mold in your fridge from time to time. Mold and other kinds of fungi are growing on your food‚ our fridge is where we do not want mold to grow. We all can see where mold grows in our fridge‚ usually it is in the produce. But did you know mold can grow almost about anywhere. You can see mold in the shower‚ garage and even you cupboards

Antibiotic Case Study 1. I would ask the patient if she uses any feminine or hygiene products. Besides pain‚ have you had any other symptoms? 2. I would expect the patient to have a urinalysis done. The presence of WBC’s‚ leukocytes esterase‚ nitrates‚ or bacteria indicates UTI. (Pagana‚ Pagana‚ 2010 pg. 1021) A urine culture and sensitivity test can be done as well. This test will indicate a specific bscterium that is present in the patient’s urine. A blood sample will probably be taken as well

Both prokaryotic cells that create bacteria and eukaryotic cells that make up most other forms of life evolve. Natural selection and genetic variation are simply the way evolution happens. This is why there is an antibiotic resistance. If bacteria are constantly changing then antibiotics must change too. Evolution is an amazing process that explains and justifies change. In New Mexico at the Carlsbad Caverns National Park there is a unique and enlightened discovery. There are many caves in the

Explain your answer a. They don’t‚ they have an antibiotic resistant. Antibiotics are there to kill and stop the growth of bacteria cells. The bacteria respond differently to the microbe. It can change its morphology‚ molecular components‚ gene expression‚

Superbugs are becoming a big problem in the world‚ but what are superbugs? Superbugs is a bacteria that becomes resistant to antibiotic drugs they carry genes that are resistant to antibiotic drugs and cannot stop the bacteria from multiplying (Staff 1). You might know of superbugs by the term multidrug-resistant bacteria. This mostly happens when people overuse antibiotics and their body becomes immune to those drugs. In very severe cases people with extremely weak immune systems usually die if they

In the 1940s antibiotics were widely introduced as a cure for common types of diseases. However‚ some of the diseases started to build up a resistance to the antibiotics and in result‚ the antibiotics became ineffective. In order to help resolve the crisis‚ antibiotics were found through screenings of soil microorganisms. However‚ soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment‚ the researchers

New antibiotics are constantly being sought for this reason. Other approaches include using combination of antibiotics and changing the chemical structure of antibiotics in the laboratory so that all of slightly different properties. These attempts have all been tried and have been successful‚ but unfortunately‚ the bacteria are
