Microorganism

The invention of microscopes have changed science and medicine drastically as it’s creation has allowed people to discover new viruses and view microorganisms which are unable to be seen by the naked eye. The microscope has also given us the opportunity to diagnose diseases such as cancer, anemia and due to the microscope’s magnification, it is also able to conduct tests such as the ‘Bone Marrow Test’. Bone Marrow Tests portray the health of the bone marrow and determine whether the bone marrow…

So I came closer and closer to the machine, I realized that this machine was the shrink ray that the teacher's were talking about. Before I could dive out of the ray's way, I suddenly was shot with a laser and I was shrunk into the size of a microorganism. I was blown by the air conditioner and there I was, on my friend's apple. My friend ate his apple, it all happened in slow motion. I could smell his terrible breath, I almost fainted, but the real hazard came…

only comprise of those three ingredients (Hardy). It was not until 1857 that Louis Pasteur discovered microorganisms were responsible for fermentation that yeast was recognized as the crucial ingredient in brewing beer (Alba-Lois and Segal-Kischinevzky); Baker 's yeast was thus aptly named Sacchromyces cerevisae, with cerevisae meaning “of beer”. Since then, culturing strains of microorganisms for food processing has generated a large diversity of novel foods and drinks, as well as enabled…

Vector carrying diseases and microorganisms seem to be adopting positively to warmer, wetter conditions and even some microorganisms are also wrecking havocs In even to cooler, drier conditions. All these support the facts that climate change is a strong factor influencing generally the health and existence of humanity, it unfortunate that microorganisms are adapting to survive in the extreme climate behavior while humans are continuing in…

Bacillus anthracis is the causative organism of the serious infectious disease, called anthrax. There are three manifestations of this disease. The manifestations include gastrointestinal anthrax, inhalation anthrax, and cutaneous anthrax. This research will explore the morphology, virulence factors, reservoir, transmission, and portal of entry of B. anthracis. The pathogenesis will also be reviewed, including symptoms, how B. anthracis causes these symptoms, the possible complications of the…

BACTERIOPHAGE MEDIATED PHYTOREMEDIATION Wastewater is any water that is against the usage by human . Wastewater is the result of domestic, commercial, industrial or agricultural activities. After the use water is returned to the environment in a different condition, usually as dirty water (wastewater).It is never returned in the same way as it was withdrawn. Wastewater produced by households or communities is also called municipal wastewater or sewage. (Tilley) Effluent refers to the sewage or…

Q3) What do you understand by “effective hand cleansing”. Describe each method separately: Transmission of microorganisms on the hands of healthcare workers is the most common cause of cross infection, occurring directly from patient contact or indirectly via contact with the environment. Hand hygiene is therefore considered to be one of the most important procedures in the prevention of cross contamination and cross infection. When to perform hand wash: Before: the beginning of the shift,…

As years have gone by, the quality of life of human beings has been dramatically improved through the discoveries of some of history’s greatest scientific minds. A major contributor of the impact of science on the today’s world was Sir Alexander Fleming, known to most people as the “Penicillin Man.” Alexander Fleming was born in Ayrshire, Scotland, on August 6, 1881 (Biography.com Editors). Sir Alexander Fleming was a doctor and bacteriologist most notorious for his discovery of the penicillin…

One of the most important physical properties of molecules is their chirality, or lack thereof which is known as achirality. Chirality is defined as the ability of a molecule to exist in two no superimposable images called enantiomers. This means that achirality is the opposite, in which molecule is superimposable on its mirror image. When two molecules are related in the fact that they are stereoisomers of each other, but are not mirror images. In nature chiral molecules do not exist in their…

method. Hanging drop technique is a well-established method for examining living, unstained, and very small organism. The hanging drop is where employs a glass slide with a circular concavity in the center into which a drop of fluid, containing the microorganism. Wet mount is the technique where a drop of water that contains the bacteria is put on the slide and covered by the cover slip to be observed under microscope. There are pro and cons in using this technique. For wet mound, it tend to dry…
