Povidone-Iodine Vapor Kills Mrsa, Benjamin Ogilvie, Jon Mitton, Jordan Tucker, Dennis L. Eggett, Richard A. Robison

Povidone-iodine is an antiseptic that is frequently used to clean skin prior to surgery. Current FDA regulations require that hospitals dispense povidone-iodine from single-use bottles, rather than large, multi-use containers, to prevent microbial contamination. This results in hospitals generating lots of product waste. However, if povidone-iodine vapor can kill microbes, then multi-use containers may be safe to use, since any bacteria that contaminated the inside of the container would soon die. The purpose of this research was to determine whether vapor from povidone-iodine could kill methicillin-resistant Staphylococcus aureus (MRSA), a common cause of hospital-associated infections.

In summary, this experiment demonstrated …

Discovery And Characterization Of Bacteriophage To Control Mrsa, Jacob B. Hatch, Bradford Berges

Journal of Undergraduate Research

About 20% of humans are carriers of Staphylococcus aureus (SA). There were an estimated 11,000 deaths in the United States in 2005 attributed to SA, with the majority caused by MRSA (Methicillin Resistant Staphylococcus Aureus) isolates [1]. Many MRSA isolates have developed resistance to all but one antibiotic drug: vancomycin. However, other bacteria have developed resistance to vancomycin, suggesting that in time MRSA will likewise become non-responsive to this last available drug and MRSA infections will be untreatable. This project looks to find an alternate method of MRSA treatment. Bacteriophage (phage) are viruses that infect bacterial cells in order …

Isolation And Characterization Of Novel Lytic Phage To Treat Mrsa, Tyler White, Bradford Berges

Journal of Undergraduate Research

The bacterium Staphylococcus Aureus is the cause of a serious skin disease that is known to cause life-threatening infections such as pneumonia, endocarditis, meningitis, sepsis, bacteremia, and toxic shock syndrome [1]. Nonetheless, most SA infections are readily remedied via antibiotic treatment with methicillin. However, over the course of frequent exposure to various antibiotics, the bacteria have evolved a mutant strain (MRSA) that is completely resistant to the drug. In 2005 an estimated 11,000 deaths occurred that can be attributed to SA, with the majority caused by MRSA isolates [2]. Albeit the mutant is named MRSA, isolates of this strain are …
