Antimicrobial Potency Of Silver Nanoparticles

Analysts have been concentrating among the dynamic parts of supportive microorganisms inside the human body, and they found out that: “In fact, most of the cells in the human body are not human at all. Bacteria cells in the human body outnumber human cells 10 to one.” (Jennifer Ackerman, 2012, p. 38) Ackerman also expresses that

Bacteria is a single celled organism, bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body, only 1% of bacteria is actually harmful.

Bacteria are ubiquitous; they can be found on the skin, in the soil, and inside the body. Because of the very nature of this ubiquity, it is important to be able to determine between different strains of bacteria. An example of this is determining the causative agent for a disease so that the patient will be treated with the appropriate antibiotics. It may be important to determine the bacteria in a certain region, because like with enteric bacteria, it is normal to find them in the digestive tract as they are in a symbiotic relationship with our bodies in this area; however, they also cause opportunistic infections in places outside of the digestive tract to our detriment, such as with a urinary tract infection. Some strains of bacteria are common to nosocomial infections, and identifying these bacteria as such helps create the guidelines for healthcare workers in antiseptic technique. All of the morphology and characteristics of each strain of bacteria help us to better understand the role of bacteria in the body as well as helps us understand how they can cause illness, and what treatment regimen to set in place. In lab this semester, a sample of unknown

It’s fascinating and a bit strange to think just how many bacteria live in our mouths, on our skin, and inside our bodies. Usually we think of all bacteria as being bad and harmful to us, but our bodies contain tons of good bacteria that play a very important

We will isolate the bacteria by plating out the root nodule extract on enriched media and typing unique colonies using 16S rRNA sequencing. Additionally, to understand how these bacterial isolates behave in the presence of other actinobacteria, we will test all isolates arising from these purity streaks against an actinomycete known as C3BA. We will observe the interaction between the C3BA companion strain and the test strain and screen for morphology, color, and the ability to inhibit or affect the growth or behavior of either strain. Finally, we will use mass spectrometry to analyze interactions that produce a visible effect, and we will search for unique natural products that may be responsible for the physiological changes observed. If the mass spectrum yields any unique compounds, we will subsequently isolate these compounds and then analyze the compound by NMR to determine the structure of the molecule. This project ties into the larger theme of identifying novel compounds produced by actinobacteria in the environment, with the ultimate goal of potentially identifying a new molecule that may have useful therapeutic

Bacteria are a very small, self-sufficient, one-celled organism that thrives in a variety of environments. However, many bacteria thrive in the mild 98.6 health body environment, some of these environmentally content bacteria in your body are actually good for you; its only 1% that isn’t.

Bacterial symbionts are predominant among organisms that shape the biological world (Hurst 1993, Wernegreen 2004). Some of the bacterial symbionts that have an inordinate influence on the health and evolution of their hosts are those bacteria that live within their symbiotic hosts, so-called endosymbionts. Bacterial endosymbionts are the focus of current research programs by the National Institutes of Health (Human Microbiome Project, http://www.hmpdacc.org/) and the National Science Foundation (The Symbiosis, Defense, and Self-recognition Program).

Symbiotic relationships are those that evolve between two organisms that interact in a specific manner with each other. These can range from being facultative, where the relationship is not required by either organism, to interactions that are obligate and are required by both organisms to facilitate survival. There are many mechanisms and processes that bacteria and their hosts can use to initiate and maintain symbiotic interactions and a few examples will be described in this report.

Bacteria are classified as microbes,which are single celled prokaryotic organisms that are invisible to the naked human eye. As diverse as humans are, microbes are even more so, having been on Earth 1,000 times longer than human beings, a total of 3.5 billion years. Because of this, microbes have evolved to inhabit practically all environments on this planet, from extreme high and low temperatures, no oxygen content, or

There are trillions of microorganisms living within us, greatly outnumbering our cells and genes. They are found in our skin, hair, membranes, mucous membranes and gastrointestinal tracts. Collectively these microorganisms are called our microbiota. Every individual has a unique microbiota, kind of like a fingerprint, but usually share similar metabolic functions. A vast majority of these are harmless and even beneficial to us, these are referred to as commensals. There are many bacterial commensals, that have co-evolved with us for centuries, making it possible for our bodies to properly function. Commensals benefit us by synthesizing vitamins and minerals, digest foods we alone cannot, regulate immunity, detox the body, protect against infections, and reduce inflammation. While there

When we speak of the word “bacteria” some individuals may not recognize how large of a role these tiny organisms play in our everyday lives. Some may jump to the conclusion that bacteria are related to the spread of germs or sickness among the human population. Most microbes are harmless or beneficial (Matthews, 2015) and a large majority of these tiny microbes are extremely important in order to maintain the balance of living organisms and chemicals in our environment (Tortora, Funke, & Case, 2013).

Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic, measuring 1 micron in length. However, colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. When considering the pH level, bacteria are classified as either acidophiles (acid-loving), neutrophiles (neutral ph range), or alkaliphiles (alkali-loving). The one that causes disease in humans would be the neutrophiles, which have an ideal pH range of 5.4 to 8.0. There are exceptions, however, like Alcaligenes faecalis and Vibrio choleae, which are both alkaliphiles and can infect humans. There are physical and nutritional factors that affect bacterial growth in the environment. Sterilization is needed to keep an environment free from bacterial growth. Failure to sterilize bacterial growth in our food products today leads to the unfortunate consequence of food poisoning.

Is the key to disease prevention, treatment, and longevity found within us? For many illnesses pervading in American society today, our bodies may hold the answer. Each individual human has more than 100 trillion bacterial cells in their gastrointestinal tract. The commensal and mutualistic relationship between this multitude of bacteria and their host has been seen to prevent and treat disease, as well as provide insight to a long, healthy life (Koboziev, 2014). The diversity of these microorganisms and their relative abundance within the gastrointestinal tract provides protection against disease and metabolism of food (Nicholson, 2012). Due to the great diversity in gut microbiota, the composition can serve as a biological fingerprint (Sunagawa, 2013). Any significant change in an individual’s gut

Bacteria plays an important role in our bodies and in the environment. In the human body, bacteria helps us remain healthy by fighting off infections, aiding in digestion, reinforcing intestinal barrier effects and enhancing intestinal cell health and growth. Not only is bacteria important for our health, but they are also important for the Earth’s environment. In these environments, bacteria plays a pivotal role in helping to keep organisms healthy and to help maintain the balance and control that are needed in these environments. In this research paper, I am going to talk about what bacteria and the many benefits that it offers to every living species that is living on thee Earth.

Antimicrobial resistance (AMR) is a problem so serious that "it threatens the achievements of modern medicine",3 and has developed faster than new antimicrobial agents coming to the market despite preventive efforts such as prudent use of available antibiotics,5 exemplifying the urgent need for additional research in this field. Antimicrobial resistance is common among organisms responsible for widespread and life-threatening disorders such as sepsis, bacteremia, pneumonia, urinary tract infections, bone and respiratory disorders. Over the past few years, antimicrobial resistance has significantly increased among gram-negatives such as Escherichia coli6,7 (E. coli), Klebsiella pneumoniae8 (K. pneumoniae) and gram-positives such as Enterococcus
