Staphylococcus aureus

Healthcare-associated infections (HAI) cause an estimated 1.7 million infections and 99,000 deaths annually in the United States costing us approximately $17-29 billion a year (Center for Disease Control, n.d). HAIs can lead to increased hospitals stays, increased use of diagnostic tests, treatment and antibiotics. The Joint Commission added the reduction of Central Line Associated Blood Stream Infections (CLABSI), reduction of Surgical Site Infections (SSI) and the reduction, incidence and…

Literature Review The majority of the literature agrees that antibiotic resistance is a serious issue that results mainly due to the overuse and misuse of antibiotics. This issue is causing a large financial impact on the health care system. A study conducted by Rajasekar, Guest, and Bodansky (2015), analyzed the medical records of 100 patients in order to ascertain whether or not these patients actually had illnesses that could be treated with antibiotics, or if the antibiotics were misused.…

In the article, "Repelling Germs with Sharkskin" written by Esther Landhuis, it discusses the benefits of sharkskin for humans. As the article unfolds, you will see a scientist named Anthony Brennan, inventor of the sharkskin texture, realized many marine animals have "crusty" skin due to the buildup of algae and barnacle. This prompted him to wonder what the skin was made up and why it was so different than other animals. The scientists soon found a process that helped them find what the skin…

Complications Cradle cap may become infected in some children. In these cases, the skin under the crust will look red and possibly swollen. Furthermore, blisters, pus, or weeping lesions may develop. Usually caused by the same skin bacteria, such as Staphylococcus aureus or Streptococcus, this may require topical antibiotic treatment. Secondary fungal infection may be treated with antifungal ointments. The infection may spread to other parts of the body to cause impetigo or school sores. The…

was a decrease in surgical site infections, which the statistics were taken from 10 procedures that were analyzed throughout previous reports. The report states that there was a “13 percent decrease in hospital-onset methicillin-resistant Staphylococcus aureus (MRSA) bacteremia (bloodstream infections) between 2011 and 2014” (“Healthcare-associated Infections,” 2016). We can assume that these decreases are due to better anti-septic techniques, both by nurses and surgeons. Although there was a…

persistence to tuberculosis. Starting Fall 2015, to Spring 2017, I worked in the lab of Dr. Michael Chikindas where I was responsible for screening naturally derived molecules for quorum sensing inhibition of AI-2 in Gram positive bacteria using Staphylococcus aureus as a reference organism. This culminated in my contributions to the paper entitled “Gemini Cationic Amphiphiles Control Biofilm Formation by Bacterial Vaginosis Pathogens” in the Journal of Antimicrobial Agents and…

bacteria may occur more than once, or have a trait in common relating to another bacterium. Additionally, under a microscope, each bacterium tested either positive or negative with a gram stain test. As shown in Table 1, of Experiment A, the Staphylococcus Aureus consisted of a perfect circle shape, it had tested positive for the gram-stain test which meant that the stain of the bacterial cells was purple, and the peptidoglycan cell walls were thick. Furthermore, Pseudomonas Aeruginosa tested…

thiol group played an essential role in bacterial inactivation. Silver Silver nanoparticles have inhibitory activity against Gram positive bacteria and Gram negative bacteria as well. Several experiments conducted against E.coli, B. subtilis, SS. aureus, methicillin-resistant coagulase-negative staphylococci, vancomycin-resistant Enterococcus faecium, ESBL-positive K pneumonia, S. typhi, V cholera to analyse the inhibitory effects of silver nanoparticles.The antibacterial activity are related…

On October 31, 2017, at 4:00 pm, I attended the Department of Biology Seminar Series hosted by Dr. Richard Gomer that helped in the Biological Sciences Building East, Room 115. The lecturer was Dr. Carolyn Cannon from the Department of Microbial Pathogenesis and Immunology at the College of Medicine TAMHSC. What intrigued me to go to this lecture was the title, “Wolves in Sheep's Clothing: Killing Bacterial Pathogens with Innocuous Compounds. Surprisingly the title did match the content that Dr.…

agar helped in final selection of the 5 isolates. To examine the antimicrobial activity of those isolates, in vitro inhibition by cross streak assay was performed, in cross streak method all the 5 isolates were able to inhibit the growth of Staphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 8739), Salmonella enterica (NCTC 6017), and Bacillus cereus. Previous studies also revealed…
