patients with iron deficiency could also be more susceptible to infections than those with a normal iron status[7–9]. In fact, iron is a fundamental nutrient for humans, but also a key element for bacteria growth[10–13]. Essentially, free iron in circulation promotes the release of siderophores by various bacteria, which in turn, allows the latter to compete with the host for the existing free iron. To enhance bacterial growth, the iron complexes formed are thus incorporated by receptor-mediated endocytosis[14

1: Applications of Epidemiology-Case Study HSA 535 Dr. Mountasser Kadrie Strayer University April, 2014 Introduction Escherichia coli (E. coli) is a bacteria usually found in warm blooded organisms such as human and animal intestines. Although there are large groups of E.coli, most strains are harmless. Other strains of the bacteria may cause diarrhea, respiratory illnesses and food poisoning. Some strains such as O157:H7 can cause kidney failure or severe anemia. Exposure to E.coli can be

in animals as well as human intestines, it comes through the feces. Increase exposure are International travel where developing countries with poor sanitation. Owning a pet bird or reptile is also a risk factor if they are infected with salmonella bacteria. Stomach has a natural defense against salmonella. Some disorders are antacids, inflammatory bowel disease and recent use of antibiotics can shorten the natural defense. Most people are infected with salmonella by eating foods that are contaminated

ENV/100 October 29, 2012 Shelby Barker Rainforest Rainforest covers about 6% of the earth's surface and is one of the most diverse ecosystems. Influencing how energy flows through this ecosystem is the fact that most f the plants living mass is above ground. There are plenty of cycle in the rainforest that make sure the flow of energy and nutrients through this ecosystem is continual. Photosynthesis is the process which energy is harnessed from the sun and used along with carbon dioxide and

and Prevention, also known as CDC, “there is no drug to treat people who get sick from the virus”. This is why people should take Sydney seriously. Another example that shows that there is no treatment is because antibiotics solely fight against bacteria and not viruses, antibiotics will not help fight this infection. The people around the world are in danger as not even antibiotics will help them fight off this vicious infection. Moreover, Sydney is highly contagious and caution should be taken

which cause disease or spoilage of beverages and food, but it is now recognized that many microbes have essential roles in our ecosystem or can be used to accomplish beneficial tasks. Human history is full of examples of major devastations caused by bacteria and viruses. Some of these historically important diseases still occur, such tuberculosis and yellow fever. Microorganisms are evolving to cause new infectious disease problems such as Lyme disease and AIDS, which capture public attention. Control
