Antibiotic Resistance and Methicillin (MRSA)

Methicillin resistant Staphylococcus aureus (MRSA) has become a big concern in hospitals throughout the country and the world and have other antibiotic resistant bacterial strains.

Part 1

The use, overuse, and abuse of antibiotics is accredited with creating these antibiotic resistant strains. Explain how this relates to natural selection.

Describe 1-2 of the things that people do (you can include individuals, doctors, health care professionals, hospitals, farmers, etc.) that contribute to this problem? Why?

Part 2

How can you prevent or slow down the spread and further the selection of new antibiotic resistant strains of bacteria?

Are there things that you can personally do to reduce your risk or even to reduce the spread of these dangerous microbes?

What is your reaction to the following sign that is commonly found in restrooms? Is it significant to the discussion of antibiotic resistance?

Solution Preview

The most prevalent antibiotic resistant infection that must be study and understand in the modern world is the "Methicillin-resistant Staphylococcus aureus (MRSA) infection". (1) It is caused by a strain of staphloccocus bacteria that has developed resistant to the common antibiotic for treating normal staphloccocuc aureus infection. These antibiotic resistant infection occurred in patients residing in hospitals. The MRSA infection in the hospitals are caused by using invasive devices or methods, such as intravenous tubing and surgeries. (1)
MRSA infection also occurred in the community and it can spread through skin contact in crowded places. MRSA infection begin with a "small red bumps that quickly turn into deep painful abscesses, which require surgical draining." (1) The Staphloccocus bacteria remain deep into the skin and can infect deep into the body causing life-threatening infections in joints, bones, surgical wounds, bloodstream, heart, and lungs." (1)

Control strategies

The most effective control strategies for reducing the transmission of MRSA is by "isolation and decolonization." (2) The method of isolation involve using disposable gloves and aprons or placing the patients in isolation wards and single rooms. (2) Decolonisation is a method that attempt to suppress or eliminate the MRSA using antimicrobial solutions like "clorhexidine and intranasal mupirocin." (2) Decolonisation reduce the bacterial community available to cause endogenous infection and transmission. (2) The two method isolation and decolonization are combined together for a more effective control if MRSA infection. After using both decolonization and isolation, another approach is to screen for detection of the bacteria that colonized the patients. There are several screening methods: simple traditional ...
