2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with

users are more likely to spread it and less likely to treat it properly. Something that I learned from the articles CDC-TB‚ MDR-TB CDC‚ and Tuberculosis NY Times was that bacteria mutates more frequently when people don’t finish their doses of antibiotics‚ which can lead to a mutated form of TB such as MDR-TB. There are different forms of TB‚ which are MDR-TB (multidrug resistant TB) and XDR-TB (extreme drug resistant TB). Medication and treatment for MDR-TB and XDR-TB is extremely expensive and

Staphylococcus aureus‚ otherwise known as Staph‚ is a bacterium that has naturally acquired resistance to many current antibiotics. Specifically‚ the MRSA (methicillin-resistant Staphylococcus aureus) strain has acquired resistance to methicillin. Staph frequently colonizes in human nasal passages‚ which serve as reservoirs for transmission. The following texts focus on Staph’s nasal colonization and mode of transmission‚ inspired by the research of Dr. Alexander Cole at UCF’s Burnett School of Biomedical

contributes to antibiotic resistance is the amount of antibiotics that are given to farming animals. Did you know that as of 2015‚ “80 percent of all antibiotics sold in the U.S. are given to poultry and livestock” (National Geographic: Should We Continue to Feed Antibiotics to Livestock?‚ 2015). Knowing the threatening consequences of antibiotic resistance‚ why are antibiotics given to cattle? The majority of the nation pays no attention to how antibiotics in cattle contributes to antibiotic resistance

“Explaining FDA’s Antibiotic Phaseout in Livestock” was written to explain the FDA’s policy about antibiotics in the feed for livestock and what the FDA believes is most important for the livestock and for human health. The Food and Drug Administration (FDA) made a plan to slowly decrease dispense of the medically important antibiotics. They do not want the antibiotics to boost the growth of the food animals or increase feed efficiency. The plan of the FDA would also consist of gradually increasing

It has been taught for several generations that hand hygiene is effectively accomplish through the use of handwashing with soap and water. Unfortunately‚ studies have shown that handwashing practices have

Resistant Staphylococcus Aureus‚ MRSA‚ is a common infection in a lot of hospitals‚ nursing homes‚ and among those with weak immune systems. MRSA infections are mostly non-life threatening but can be fatal if left untreated due to its resistance to antibiotics commonly used. Even a healthy person can be a “carrier” and not be infected. To aid in the prevention of MRSA infection‚ hands should be washed using soap and water or cleansed with an alcohol-based hand sanitizer. Wounds need to be covered with
