Superbugs
Thesis: Antibiotic resistance is no new problem. Alexander Fleming acknowledged that bacteria would learn to resist antibiotics when he first discovered penicillin. Bacteria did exactly what he said it would, but until now, the answer to resistance was upgrading to a higher dosage of an antibiotic or a stronger version of it. This is where the new problem lies: there are certain bacteria, known as superbugs, which have learned to defy even the strongest of antibiotics, and due to unawareness, the general public is increasing the problem by demanding antibiotics when they aren’t needed.

b. How bacteria learn to defy antibiotics and anti-microbials
c. Disinfectants role in bacterial resistance (tricolsan is the main problem).
d. Development of superbugs
e. Vancomycin-why its no longer effective
II. New ways to fight superbugs
a. Honey, copper, and garlic-how they may help in combating superbugs
b. Bacteriophages and their role in fighting superbugs from the inside out
c. Developing vaccine
III. Education and Superbugs-What the general public needs to know
a. Doctors need to learn how to recognize a superbug when they see it and also need to be aware of proper treatment
b. Misuse of antibiotics and how doctors can teach patients to avoid it
c. Different types of superbugs
d. What MRSA is and how it affects your immune system
e. How to avoid contracting a superbug (good hygiene)

Fixing my bib
1)Develop the significance of the subject for my audience more clearly.
2)Add categories for organization
3)Double check to make sure I have used the right format (indentions)
4)Elaborate on how my sources benefit my paper and therefore audience

Anti-microbial resistance is no new phenomenon. Alexander Fleming, the creator of penicillin, acknowledged the problem of anti-microbial resistance in a 1945 New York Times interview. The most recent problems with anti-microbial resistance are the lack of new antibiotics when the old ones stop working. There are many different ideas as to what is causing the resistance, but it is mostly attributed to the unnecessary overuse of the once dubbed all-purpose drugs. Patients are demanding a prescription from doctors over the phone, and are given the prescription for what is usually a virus. It is estimated that "20 to 50 percent of the 145 million antibiotic prescriptions given each year to outpatients are unnecessary"(p.5). Often times, patients don't follow the dosage for prescriptions and don't finish them-another culprit for creating drug-resistant bacteria. If patients were properly informed and all cases were properly documented, superbugs would be a lot easier to manage.
The problem with the superbugs that are created due to antibiotic overuse is not that they are more dangerous, just harder to kill. The last resort antibiotic, vancomycin, has already met its match in a few cases. The most effective measure thus far in prevention of superbugs is good hygiene, including hand washing and showering after workouts. Taking medication until it is all gone is another good measure to take. Scientists and pharmaceutical companies are working on the problem, but it could be another five years before they come up with a solution.

Annotated Bib Entry #1
Antibiotic resistance is becoming an almost unstoppable problem in today's health care. Bacteria naturally develop resistance to antibiotics, and instead of just increasing the dosage or using the next strongest antibiotic, health care providers are running out of options. One of the biggest problems in antibiotic resistance right now is methicillin-resistant staphylococcus aureus, more commonly known as MRSA. This bacteria was seen in mostly hospital patients until just recently. It is starting to infect people outside of hospitals, where it is then referred to as Community Acquired MRSA. The problem with CA-MRSA is that it is becoming resistant to almost all antibiotics except for vancomycin-the strongest, last resort antibiotic. Even so, there have already been a few cases of vancomycin resistant staphylococcus, which leaves us with nothing to fight the bacteria with. Some may argue that the answer is the careful monitoring of antibiotic distribution. It may be able to keep track of what is distributed in America and other developed countries, but there are too many countries which allow patients to pick up an antibiotic at the pharmacy without a prescription. There are a few developments in the fight against MRSA, such as using the anti-infective properties of honey and the use of "bacteriophages-viruses that invade certain species of bacterial cells and cause them to burst and die"(p.22). Even with these new remedies, it is important to remember how dangerous MRSA is, and to know how to avoid it. Hand washing is the most important step in preventing the spread of bacteria. Soaps with the antibacterial triclosan should be avoided, however, as they contribute to antibiotic resistance. It is also very important to take all of a prescribed antibiotic as stopping when symptoms subside could leave the stronger bacteria behind.
I can use the information from Clemmitts article to explain what MRSA is, how it is aquired, how to prevent it, and how the FDA and drug companies are working on a solution.
