This activity of the catalase in the escape of the host’s immune reaction has been shown in a murine animal model (Das and Bishayi, 2009). What was not mentioned in the primary reference is that what is so distinct about MRSA is the fact that the bacteria cannot be killed by the most common antibiotics, penicillin and cephalosporin groups, characterized by their beta-lactam ring. Briefly, these antibiotics prevent the production of the bacteria’s peptidoglycan-rich cell wall by inhibiting transpeptidation. MRSA contains beta-lactamases that bind to beta-lactams, and render these bactericides inactive (Agrawal, n. d.). Effectiveness of alkaline solution against MRSA infection It has been proposed by Shannon Brown (2010), in his article, “End of MRSA-How?”, prevention of MRSA infection simply involves avoiding acidic food products and stress, which increases the acid in the digestive tract. According to Brown, the acidic environment allows the normal flora of the gut to die and the acidophilic MRSA to thrive. The solution to a potential MRSA infection is said to lie on increasing the pH of the environment to which it is exposed to. Despite the seemingly simple solution to the problem of MRSA infection, prevention still poses a great challenge as the current food products available in the market are cultivated using acidic fertilizers and pesticides. Many people also enjoy drinking coffee, tea, wine and alcohol, all of which make the gut more acidic. As such, the article suggests that alkaline solutions can prevent uncontrolled MRSA growth in the body. Specifically, taking in pHenomenal, an alkaline water concentrate, as food supplement is said to potentially increase the pH of the digestive tract, and to subsequently prevent MRSA infection. Such activity has been shown through an in vitro pH neutralization test, whereby lactic acid was neutralized by pHenomenal at approximately 1:22 acid-to-pHenomenal ratio. Another alkaline product suggested to prevent MRSA infection is B-pHree, which can be applied on the skin, where MRSA normally resides. In an antibacterial efficacy assay done on this substance, it was found that it effectively inhibited the growth (100% growth reduction) of Staphylococcus aureus inoculated in Tryptic Soy Agar (TSA) incubated for 24 hours. Despite the promise of MRSA prevention and the availability of prophylactic measures, there are potential problems regarding the claims of preventing bacterial infection by increasing the pH in the gut. Literature review Normally, the stomach is highly acidic, with pH of approximately 2. This acidity is a strategy to control the activity of pepsin, which catalyzes the breakdown of proteins into organic compounds that can be used by the body in its various physiologic processes. In addition, the highly acidic environment of the stomach prevents the growth of most pathogens that cannot thrive in such extreme conditions. In fact, it has been shown by Suzuki (1994) that the low pH of gastric pH is directly related to decreased amounts of pathogenic bacteria such as Staphylococcus and MRSA in the gut. In addition, it was found that cancer patients before and after operation, who have high levels of gastric pH are more likely to have Staphylococcus and MRSA in the gut. Although the in vitro experiments have both supported ...Download file to see next pagesRead More

Role of the kidney and urinary pH in aspirin poisoning
Aspirin functions by inhibiting the production of prostaglandins, body chemicals that are necessary for blood clotting and are noted for sensitizing nerve endings to pain (Marx, 2006). Due to its ability to inhibit the coagulation of blood it has also been used as an anticoagulant in the treatment of such conditions as unstable angina or following a minor stroke or heart attack.
