One day‚ allowing me to contribute to scientific community‚ the field of public health‚ and science communication. Acquiring a PhD in Microbiology and Immunology will allow me to pursue employment with the government’s public health sector. Throughout my professional career as a scientist‚ I would like to investigate how mechanisms of virulence operate in infectious diseases. Then one day

This report by Wright‚ Seiple‚ and Meyers discusses mainly the history of antibiotics as well as its link to future discoveries. Each section in the report examines different points throughout the essay: 1) The authors suggest chemical synthesis as the key to the development of the first antibiotic. All antibiotics discovered by humans have been categorised into one of the following: natural products (manufactured directly by bacteria)‚ semisynthetic antibacterials (manufactured by chemical synthesis
Premium Bacteria Antibiotic resistance Antibiotic
Antibiotic resistance results from bacteria changing in ways that make those antibiotics no longer useful. Resistance is a common yet problematic issue in treating pulmonary exacerbations or infections in people with Cystic Fibrosis (CF). Not all bacteria are bad. However‚ there are some that can cause infections. As bacteria are exposed to antibiotics over time‚ resistance may develop‚ and the number of antibiotics we have to kill the bacteria decreases as well. Thus‚ it is important to learn
Premium Antibiotic resistance Bacteria Staphylococcus aureus
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

H1N1: The Sneaky Killer I chose to write my topic paper on the H1N1 virus. This virus has interested me since its reemergence in 2009. Its ability to change and adapt each time it shows up again attracted my attention. I hope to inform people about the virus along with the symptoms and how to go about avoiding it if you can‚ or treating it if you have it. This pandemic is avoidable through a simple vaccine that can be taken as a shot or as a nasal spray. Overall I find the H1N1 virus to be interesting

Microbiology in the News: Fecal Transplants Zimmer’s article on fecal transplants (2016)‚ discusses how the effectiveness of transporting healthy stool to sick individuals has led to a series of unanswered questions and beliefs. For years scientists were unsuccessful in finding a use for this type of treatment. The breakthrough came about during a trial experiment using the procedure to treat a serious bacterial infection; Clostridium difficile. Clostridium difficile is a bacterium that causes
