Over 1.2 million patients in the United States get a staph infection each year, and 90,000 of those cases lead to MRSA (Reinberg, 2007). This puts finding a drug or method that is not resistant to staph as a priority. The current treatment options for staph are antibiotics, penicillin, wound treatment, and device removal. The human body is becoming more resistant to antibiotics, and there are strains of staph that will not react to the use of antibiotics. The medical world is trying many different things to stop and kill the growth of the bacteria without using antibiotics. More doctors are considering the use of blue light therapy. In 2009, patients that acquired a staph infection that led to MRSA in a hospital participated in a clinical trial with blue light therapy. This clinical trial was extremely successful. Over 90% of the patients that participated became free from the infection much faster than when antibiotics and penicillin were …show more content…
After researching blue light therapy, we researched more forms of therapy for superficial infections and illnesses. Many patients participate in UV light therapy. UV light therapy is the use of UV light to treat a variety of skin disorders, such as eczema, psoriasis, vitiligo, pruritus, and t-cell lymphoma. Because staph is a skin infection as well, the UV light therapy could potentially react with the infection as it did with the other assorted topical infections and reduce the growth of the staph (Bishop, 2010). Accordingly, the purpose of the experiment is to determine what the effect of UVA light is on Staphylococcus epidermidis. The hypothesis for this experiment is if the exposure of the ultraviolet light wattage increases, then the growth of staph will decrease when the growth of staph is a function of ultraviolet light. Moreover, the almost all of same form of UV light will be used. The three sources of UV light will be sunlight, which has a mixture of UVA and UVB light, tanning light, and black light. Each light has a source of UVA light. The reason this form of UV light is being utilized is because of the penetration that these lights have. UVA lights have rays that cause 500 time more exposure than an UVB light (University of Iowa Hospital). In addition to being more powerful, the waves are almost 100nm longer than UVB. Therefore, UVA lights will cause a faster and more noticeable reaction and
