Antimicrobial

Antimicrobial resistance has been increasing throughout recent years. One reason is due to a prevalent use of antibiotics as growth stimulants in livestock. The bacteria in the livestock become resistant due to constant exposure to the antibiotics. When the meat harvested from these animals is packaged and sold, the bacteria are now exposed to the human population. This bacterium can make its way into the human body and cause various illnesses. Illnesses that were once easily cured with…

Antimicrobial agents are agents that kill off microbes or make them less harmful to other organisms like humans. They are classified into three types. The first type is Antibiotics, these are antimicrobial agents that come from other microbes and are used to kill bacteria. They are typically taken internally and they act differently depending on the organism. The second type is Antiseptics, these are microbial agents used on the skin and they are harmful to microbes. The third type is…

Surgical procedures lead to contamination of previously sterile tissues or fluids, surgical prophylactic antimicrobial therapy (SAP) is an initial administration of short course of an antimicrobial agent before the surgery to prevent development of infection , SSI is 3rd most common nosocomial infection in US acute-care hospitals (14-16%),Complicates 5% of surgical cases overall, Increases hospital length of stay by approximately 10 days ,Increases readmissions to hospital ,Increases morbidity,…

Antimicrobial resistance has long been a topic of research due to the increase prescription of antibiotics. According to the Center for Disease Control and Prevention, antimicrobial resistance is defined as a microbe’s ability to change when exposed to antibiotics and allow them to resist the effects1. This causes the antibiotics to be unsuccessful in treating bacteria. Antimicrobial resistance happens when a bacterium has the ability to survive against antibiotics causing a selectivity for the…

there are any household substances that have antimicrobial properties. For the purpose of this lab, we will consider a substance to have antimicrobial properties if it produces a measurable zone of inhibition within an E. coli culture. A zone of inhibition is the area around an antibiotic disc that contains no bacterial growth. Turmeric was tested because curcumin, the compound that gives turmeric its bright yellow pigment, has well-known antimicrobial properties (ACS). We also tested cinnamon…

Silver nanoparticles have unique antimicrobial properties. They have a variety of applications: diagnostics, wound healing, pharmaceuticals, etc. These nanoparticles destroy bacterial cells walls and interrupt membrane integrity by their electrostatic attraction to the negatively charged bacterial cell walls [10]. Metal nanoparticles are usually synthesized by chemical techniques which is costly and highly toxic. Currently, there is a growing demand for alternative methods that would limit the…

healthcare concern of Antimicrobial Resistance (AMR). Antimicrobial resistance is a prevailing issue since the discovery of the first antibiotic Penicillin in 1928. There are 5 mechanisms which allow resistance to impede new antibiotic development for the last 29 years (WHO, 2016) consisting of mutations in target genes, enzymatic resistance, latency, antibiotic efflux and non-specific mutations. Latency and antibiotic efflux are some of the most detrimental mechanisms on antimicrobial…

decrease susceptibility and resistance to many antibiotics used to treat them. It has been seen that “it may be influencing both the emergence and transmission of antimicrobial resistant STI pathogens.” (1) One of the biggest factors of why this disease has not been able to be treated is due to its impressive ability to have antimicrobial resistance (AMR). This continues to make things harder for researchers because they might think they have found a treatment just to have it be counteracted…

jejuni strains obtained from the Michigan Department of Health and Human Services (MDHHS) over a five year period. Hypothesis: Trends of antimicrobial resistance will continue to increase in Michigan. These trends will be vary from those reported by the national antimicrobial resistance monitoring system (NARMS). Aim 2: Determine if multiple-locus variable number tandem repeat analysis (MLVA), and single nucleotide polymorphism (SNP) molecular-typing methods…

Introduction: The effectiveness of Antimicrobial agents against Microorganisms Population of microorganisms or growth are killed and/or inhibited by natural or synthetic chemical antimicrobial controls (Madigan, et al 2012). Antimicrobial agents are grouped according to their efficacy against microorganisms. Bactericidal that kill and bacteriostatic prevent and/or reduce growth (Madigan et al, 2012). Harmful pathogens are targeted with different antimicrobial agents according to their toxicity…
