Concepts of microbiology Affiliation: Microbiology involves the study of microscopic organisms-bacteria, viruses, fungi and protozoan as both disease causative agents and for beneficial purposes. Branches of microbiology include environmental, medical, industrial, agricultural, water and food microbiology. Microbiology is applicable in everyday life in various ways. Personal hygiene prevents autoinfection with bacteria. Regular and thorough washing of hands with soap and water, cleaning and disinfection of the clockrooms and bathrooms minimizes risk of feco-oral infections. Garments are disinfected during washing because they trap disease-causing microbes too (Pommerville 2010).
Food fermentation is the anaerobic conversion of carbohydrates to alcohol using microbes such as Saccharomyces spp, Lactobacillus spp. It results in products variety that can be preserved for long. Fermentation products include cheese, alcoholic drinks, sauer kraut among others. In agriculture, microbiology has improved soil characteristics and increase plant productivity. Biofertilizers that contain living organisms such as Rhizobium, Azotobacter help in nitrogen fixation, solubilizing phosphorous and stimulating plant growth hormones. Manure from animal waste contains microbes that help in soil aeration. They are cost effective and reduce soil pollution through use of inorganic fertilizers.
Food preparation involves thorough washing of fruits and vegetables and cooking of foods. This ensures any harmful microbes are killed. Examples are milk pastuerization and boiling of drinking water. Utensils, pots and surfaces in cooking areas should also be thoroughly cleaned. Proper waste disposal reduces environmental pollution. Degradable matter is breakdown by microbes to form manure. Sewage water is drained into septic tanks where it is processed before discharge into rivers and streams. Nondegradable waste products are burnt and others recycled. A student is able to learn microorganism identification using the various characteristics of microbes. They are able to use differential, selective or enrichment media to grow microorganisms, gram staining and microscopy to identify cell structures, components and other morphological characteristics.
Understand current and emerging topics in microbiology in relation to healthcare. Advances in microbiology diagnostic techniques have evolved. Research is ongoing on issues of drug resistance. Current research studies on use of microorganisms as gene vectors in disease treatment. Microorganisms are used for production of cellulose, solvents, enzymes, amino acids, biopolymers such as polysaccharides and polyesters are produced by microorganisms. Corynebacterium spp is used in production of L-glutamate and L-lysine.
In pharmaceutical microbiology, mass drug production using yeast such as Streptomyces and Penicillum. Ensuring the drugs contains minimum contaminants and they are safe and effective for use. Vaccines are made from weakened or killed forms of a microbe or its toxins. They stimulate the body’s immune system to recognize it and keep memory. Involves knowledge of vaccine type, dosage, storage and the type of immune response it stimulates.
Clinical practices include clinical presentations of a disease in diagnosis which vary depending on host immune mechanism. It involves analysis of the patients’ history, specimen collection and processing. In combination diseases can be diagnosed accurately. Respiratory syndromes, both bacterial and viral may have similar symptoms (Pommerville 2010).
Antibiotics act against microbes that cause disease in the body e.g. bacteria and fungi. Prescription and administration of antibiotics and other drugs depends on disease progress. Knowledge of drug composition is also important. Underdose of drug may lead to drug resistance; overdoses are harmful to the body and may be fatal.
Microbiology involves public health, disease control and prevention. This deals with healthcare at a population level rather than on individual level. It’s educating the community on how to reduce risks of infection by microbes. It encourages early diagnosis and reduces the negative impact of disease-related complications.
Maintaining sanitation in a hospital involves disposing used equipment and using sanitizing agents to minimize nosocomial infections. Sterilization and disinfection procedures used use of ethanol, acetone, ethylene dioxide, radiation and autoclaves among others. Washing of hands between patients contact is important.
Understanding host defense mechanisms, skin, mucous membranes that prevent microbes from entering the body. Specific immune responses from the lymphoid system and antibodies, nonspecific immune responses protect the host against infections. These factors determine the virulence and degree of resistance or susceptibility of host.

Evaluating, Narrating, and Describing the narrator’s doting husband, who she describes as “very careful and loving, and hardly lets me stir without special direction” (p.2). These show that the overall setting of the story is not one of an ideal marriage, but one of misery and oppression. In fact, this is already made obvious at the start of the story where the narrator states, “John laughs at me, of course, but one expects that in marriage” (p.1). In the narrator’s description of the room, “the windows are barred for little children, and there are rings and things in the walls,” one can easily see that the details of the room can be attributed to a room that is used to isolate an insane individual. Eventually, the narrator identifies herself with the...

Describing a depth experience

...DEPTH In John Haught’s superb mediation on faith and science in the contemporary world, he describes what he calls “depth Scientists make a tacit assumption that the world is always more than what first impressions yield. But religion also assumes that there is more to the world than what appears on the surface, indeed infinitely more. In theologian Paul Tillich’s terms, religion is a state of being grasped by the inexhaustible depth that lurks beneath the surface of our lives and of nature too. In religious experience we do not so much grasp this depth as allow the depth to grasp us. Depth takes hold of us in such a powerful way that we can neither deny it nor master is . . . 1 For those of who still maintain religious belief... in these...

... Describing the Warfront Caption We have long forgotten the ritual by which the house of our life was erected. But when it is under assault and enemy bombs are taking their toll, what enervated, perverse antiquities do they not lay bare in the foundations! What things were interred and sacrificed amid magic incantations, what horrible cabinet of curiosities lies there below, where the deepest shafts are reserved for what is commonplace? In a night of despair, I dreamed I was with my best friend from my schooldays (whom I had not seen for decades and scarcely ever thought of at that time), tempestuously renewing our friendship and brotherhood. But when I woke, it became clear that despair had brought to light like a detonation... by the...
