Essay On The Antibacterial Effects Of Microorganisms

Microorganisms are both beneficial and harmful. These microorganisms are important to humans because they play a role in the ecology of life, by decomposing wastes, both natural and man-made, such as creating nitrogen fertilizer at the root zones of certain crops. Other several pathogens that can cause serious harm, even immediate death due to the diseases or disease causing products they produce. Overall, microorganisms play an important role in life.

Moisten the filter paper in the funnel with a little distilled water, and make sure that the moist filter paper fits snugly in the bottom of the Buchner funnel with no folds or bends in the filter paper visible. Use the thick rubber tubing from your drawer to provide vacuum from the “aspirator” to your “filter flask.” Be sure you are connecting the tubing to the “aspirator,” not to the water or gas outlet. Turn on the water to a low volume to create a vacuum in the filter flask but not so much that you flood the sink.

The bacterium is largely spread in nature and be present in soil, water and contaminated foods. Animals and fresh produce are prone to contamination in foul environment. How this affected Enterprise Food, is the factory workers were in the presence of the bacterium while they were producing the perishable, and from the above research listeriosis shows that it has the ability to affect the working environment through oxygen ‘inhaling’, and through quality checks when the quality in spectator test the product as for quality protocol by tasting the perishable meat. Infection of the bacterium can cause in mild to severe febrile gastroenteritis and in pregnant women, the bacterium can cause pregnancy loss. (National institute for communicable

Effective treatment of infections depends on selecting the source, site, complete medical history, also, conduct a physical assessment to identify the signs and symptoms consistent with the current infection. Other factors include patient’s age, weight, present health condition and the severity of the infection should be put into consideration (Arcangelo & Peterson, 2013). The purpose of this paper is to describe the categories of antimicrobial agents, also, description of the differences between viral and bacterial infections will be reviewed. In addition, explain why proper identification of viral and bacterial infections is the key to selecting the proper antimicrobial agent.

It is undeniable that the recent discovery of antibiotics and disinfectants in the past century is leading to the creation of increasingly dangerous antibiotic-resistant bacteria. Super bugs like Methicillin-resistant Staphylococcus have begun breaking out in hospital areas, killing more and more patients due to the lack of people following through with simple safety measures. In order to stop the creation and spread of antibiotic-resistant super bugs, proper precautions must be taken such as avoiding antibacterial cleaners, following through with instructions when taking prescriptions and maintaining adequate hand hygiene. Through adhering to basic safety rules, the creation and spread of super bugs can be minimized and all together

Whether we like it or not bacteria is everywhere, it can be good and bad, on every surface we touch and even within our bodies. Bacteria, usually as a single celled microorganism, is almost harmless on its own as it can be engulfed by phagocytes and even destroyed by antibiotics. However, bacteria can group together and create something called a biofilm, which can be more detrimental to the health of humans. Biofilms are defined as a complex structure adhering to surfaces that are regularly in contact with water, consisting of colonies of bacteria and usually other microorganisms like yeasts and fungi. (Dictionary, 2002) What they are in not too complex words are microorganisms that stick together to become bigger and stronger cultures. The initial bacteria that attach themselves to surfaces do so by using weak, reversible, short-range electrostatic forces. These forces are called the van der Waals forces. If the bacteria is not disturbed and further grows, at this stage it begins to release a sticky polysaccharide, called extracellular polymeric substance (EPS) that allows the bacteria to strengthen and promote the arrival of pathogens. These

On the other hand, bacterial contamination of the food can be occurred at various stages throughout the food processing and production chains beginning from the farm stage until the consumption stage. Foodborne bacterial pathogens have the capability to be attached in the form of biofilms on the surfaces of food industrial settings and equipment, these biofilms are resistant to most disinfections and become the main causative agent of bacterial foodborne persistence in the food production and processing chains. The control of foodborne bacterial pathogens and production of microbiologically safety food products are worldwide fundamental challenges concern both human health and worldwide economies. The unique properties of nanoparticles including their characteristic size, surface area, shape, as well as their amazing antibacterial properties especially against major foodborne bacterial pathogens, all offers great promise in solving bacterial food contamination facing food processing and production

Recently, persistence of foodborne bacterial pathogens in food processing environments has become of great impacting hazards to the public health as well as increases risk of microbial food contamination (Pricope et al., 2013; Larsen et al.,

“Infections caused by microbes that contaminate the food supply are a frequent reminder of the complex food web that links us with animal, plant, and microbial populations around the world. While we are all at risk, the elderly, the very young and those with compromised immune systems are most vulnerable.

Very hot environments can influence a variety of different bacteria in a variety of different ways. Food preservation is an example of a hot environment because it is the canned goods that go through this process so that they stay good until opened to consume (Tortora, Funke & Case, 2015). A hot environment is also used to sterilize a variety of different things such as the use of laboratory media, glassware, and hospital instruments (Tortora, Funke & Case, 2015). Within these two environments it is the heat that kills microorganisms by transforming their protein shapes causing them to inactivate. Very hot environments can react differently based on three different concepts. One concept is ‘thermal death point’ which is the lowest temperature that a microorganism within a liquid

The fact that each bacterial species, and even some of their respective strains, responds uniquely to a given antimicrobial makes it necessary to have methods, which provide researchers and clinicians with measurable susceptibilities. This need has become prevalent since the rising of later generations of antimicrobial compounds achieved by chemical modifications of the naturally occurring antibiotics. By utilizing the Kirby-Bauer method, researchers and clinicians are able to determine the susceptibility of given microorganisms to different antibiotics and antimicrobials. While antibiotics specifically target bacteria, antimicrobials cast a

The effects of antiseptic on both gram positive and gram negative microorganisms have been researched and well documented in comparative studies. Such antiseptics include

Bacteria are microorganisms that are well known to be the major cause of why people get ill. Many of these microorganisms in the world are pathogenic by nature but are treatable by a wide number of antibiotics, some are normal flora in the body, and others are opportunistic ones. In recent years, scientists formulated specific antibiotics that would eliminate and eradicate these pathogenic types of microorganisms, but there are still some microorganisms that are present today that is hard to eliminate due their capability to tolerate antibiotics.

Dr. H. Scott Hurd, author of, “The Other Side of Antimicrobial Resistance” is writing to contradict thought that antibiotic-resistance is becoming a complete global threat. (2012) the article gives several counter claims that lead you in a different mindset than simply health care precautions. The author talks about foodborne illness been linked to antibiotic resistance in modern medicine, also about the important knowledge that can be taken away from antibiotics when researching HIV/AIDS, Methicillin-Resistant Staphylococcus Aureus (MRSA), and hospital-acquired infections through research and development. The author is showing the readers that there is another side, such as, not needing to be concerned about resistance to any antibiotics because scientist and others have an understanding of certain guidelines when it comes to the patients’ health. Therefore, each excuse people are giving to support the claim antibiotic-resistance is a threat to people. He states in his writing, “As soon as an antibiotic is first used, resistance begins to develop.” He is wanting to imply in his message that even though over-prescribing is a big factor, even as simple as the first time an antibiotic is prescribed it is having effects on the patient. However, according to the Mayo Clinic, in “Antibiotics: Misuse Puts You and Others at Risk” it infers the overuse or misuse of antibacterial drugs can make resistance develops even faster, causing an epidemic before scientists can find a

The discovery of antibiotics is arguably the greatest contribution to modern medicine. The widespread use of antibiotics along with vaccines had paved the way for the treatment and cure for many of the otherwise fatal bacteria diseases and this led to a decline in the mortality rates in the mid-20th century. The use of antibiotics in medicine today to treat diseases have not all been met with positive outcomes. As a matter of fact, its relative ease of access and abundance has given rise to a major problem in creating new strains of bacteria that are able to resist our antibiotics today. Such is the case for a special type of bacteria, Staphylococcus aureus, a gram-positive bacterium with a spherical shape which in some strains of this particular species has ultimately developed resistance to virtually all antibiotics we have present today. Staphylococcus aureus is often found on skin surfaces in humans colonizing about 30% of the human population [1]. They generally are not pathogenic until they enter inside the body through an open wound or colonize other areas of the body of which they generally are not found [1]. Staphylococcus aureus commonly cause non-fatal skin diseases such as folliculitis, cellulitis and abscesses however, they can invade the circulatory system and cause a serious infection known as bacteremia [1,9]. Bacteremia is often common in a hospital setting where patients are exposed to invasive procedures such as surgeries which allow colonies of S.
