Pages: 4 Words: 1305

Microbiology & Spontaneous Generation
Microbiology is the study of microbes that are practically invisible to the human eye. Although microbes are usually associated with causing and aiding disease, they are essential organisms in the ecological world. They allow for life to thrive and are of great interests for food, scientific, and medical industries (Black, 2008). The term microorganism encompasses bacteria, protozoa, fungi, archaea, parasites, algae, prions, and viruses (Nester, Anderson, & oberts, 2012). Each of these types of microorganism is responsible for everything that can essentially cause illness in living organisms, but are also necessary for the proper functioning of a mammal's digestive tract. However, in early scientific history, as illnesses were being investigated and the cell theory was beginning to emerge, the question about whether life could come out of nowhere was being explored. Because the majority of microorganisms were practically invisible, early microbiologists did not understand the concept of…...

Pages: 3 Words: 1009

Microbiology
Microbes

Microbial metabolism is referred to as the manner in which microbes find their nutrients and energy that makes them live and reproduce. The paper will describe metabolic requirement for Staphylococcus aureus and Clostridium botulinum that provide them with environment that support their growth. The paper also summarizes mechanism of action by which drug inhibits the growth of Pseudomonas aeruginosa.

Staphylococcus aureus

Staphylococcus aureus is as facultative anaerobic gram-positive cocci that is able to occur in irregular, in pairs or in single cluster. It tends to be catalase/coagulase positive, non-spore forming and nonmotile. The real colonies have a color that ranges from yellow to golden yellow, slightly raised, smooth as well as hemolytic on 5% sheep blood agar. Nevertheless, most of the strains may as well look non-hemolytic and dirty white.

Generally staphylococcus aureus is known to find their breading environment on the skin as well as mucous membranes that belongs to warm-blooded animals…...

Microbiology How to Discover the Causative Agent
Pages: 5 Words: 1837

Microbiology
How to discover the causative agent of a new disease and its mode of transmission:

The standard epidemiologic triangle model of infectious disease causation, asserts that communicable diseases are the result of the contact between the agent, surroundings and the host with the vector. Transmission in particular happens if the agent leaves the host or reservoir via an exit portal and then it is moved (transmitted) in a particular form and enters a vulnerable host, infecting it through a suitable portal of entry. This cycle is also is widely regarded as the sequence of infection.

The locale where the infectious agent usually breeds and multiplies in number is its reservoir. The environment, animals and humans are some of the reservoirs. A contagious agent can be transmitted to a host either directly from a reservoir or through other intermediary sources. There are several different ways by which diseases spread from the natural reservoir…...

Pages: 4 Words: 1252

This is primarily because two sprouting facilities in two states were linked with the implicated alfalfa sprouts and only one lot of seeds from Idaho State was common to Michigan and Virginia. Therefore, the likely point of contamination include during growth or harvesting, seed processing, in storage, or during transportation of the food. This implies that the identification of the actual point of contamination requires collection of more information on each of these steps.
Question 17:

The results of inspection of the alfalfa fields indicated that the three possible source of contamination include cattle manure, deer feces, and irrigation water. Generally, cattle are the basic reservoir for E. coli O157:H7 while other animals like deer can either be carriers of or become infected by the bacteria. Therefore, inspecting the alfalfa fields and harvesting process may require consideration of the site of the fields, soil, fertilizer, pesticides, irrigation water, harvesting and processing…...

Quality in the Clinical Microbiology Laboratory
Pages: 10 Words: 2946

Quality in the Clinical Microbiology Laboratory
The objective of this study is to define quality in the microbiology clinical laboratory including its major components. Toward's this end, this study will examine what constitutes quality in the laboratory setting and will list and discuss the activities in the laboratory that are designed to assure quality from collection of specimen to reporting.

Quality management in the clinical microbiology field was initiated in the decade of the 1960s with government and professional societies alike introducing proficiency testing and laboratory inspection and accreditation programs. It is reported that there were many laboratory scientist and pathologists "independently active and creative in expanding efforts to monitor and improve practices." (artlett, et al., 1994, p.1) The emphasis in the beginning was on intralaboratory process with attention later shifting to such as "physician ordering, specimen collection, reporting, and use of information." (artlett, et al., 1994, p.1)

Certainly, the fact that I signed up for the course both times I was given a form is an indication of my understanding of my responsibilities and my desire to fulfill them. When I was not scheduled for these classes, I assumed I still had some time to meet the requirements in a future semester. However, I am learning only now that due to the aforementioned inconsistency between the handbook and the curriculum itself, that there is a requirement for this course to have been completed before I am able to move on the next tier of my education.
I do understand and respect the rules of this institution. However, in my current position, I am imploring you to consider that this misunderstanding was a reasonable one and that I might be entitled to be made an exception. Certainly, I have had every intention of taking the required microbiology course.…...

Microbial World
The history of Microbiology

Microbiology dates back to the 1600s. This is when there was recorded evidence of scientists collecting and observing micro organisms. obert Hooke was the first person to do so, as he studied strands of fungi among the different cells he observed. In the 1670s, Anton van Leeuwenhoek conducted research on protozoa, fungi and bacteria. After he died, is when the theory of spontaneous generation was developed. This is because there were only a handful of experiments to support his claims. Under the theory, it was believed that life forms emerge from lifeless matter such as beef broth. This debate continued until Lazzaro Spallanzani and Francesco edi disputed it through a series of experiments that were conducted by them. (Bastian, 2001) (Black, 2008)

In the late 1880s, Louis Pasteur concluded that bacteria can make someone ill and demonstrated how it will have an effect on all organisms. His…...

Biology Microbiology Gt-Sc1 Tuberculosis TB
Pages: 4 Words: 1191

M. tuberculosis can extend to other tissues or organs such as the lymph nodes, joints, skin, bones, the central nervous system, the urinary tract and the abdomen. The host immune reaction to M. tuberculosis originally involves the employment of activated macrophages to the site of infection in the lung, where they can form a tuberculous granuloma that serves to restrict the infection. Bacteria that are trapped in the granuloma face aggressive surroundings that become anoxic and rich in toxic fatty acids. M. tuberculosis under these circumstances has been assumed to take for granted a dormant status in which it can remain viable for years without causing observable disease. A succeeding breakdown of the immune system of the host may permit its emergence from this dormant status, resulting in reactivation of the latent disease (Manganelli, Dubnau, Tyagi, ussell and Smith, 1999).
In order to diagnosis TB a doctor will complete a…...

Phylogenetic Analysis of the Black Plague
Microbiology Article eview

The first successful sequencing of an ancient bacterial pathogen was reported in the October 27, 2011 issue of Nature (Bos et al., 2011). Samples of Yersinia pestis, otherwise known as the Black Death, the Black Plague, or the bubonic plague, were recovered from the teeth and bones of victims interred in a 14th century burial ground outside of London, England.

Y. pestis DNA was recovered from five teeth and the authors found a C. To T. damage pattern previously shown to be characteristic of endogenous ancient DNA. The recovered DNA fragment length averaged around 55.5 base pairs, which is also consistent with ancient DNA. These findings help to confirm the recovered samples had not been contaminated with extant strains of Y. pestis.

After validating the technical approach, which was a capture-based array method, the authors were faced with aligning the very short reads in order…...

Corynebacterium diphtheriae is a bacterium that is pathogenic and is the leading cause of diphtheria. Due to the resemblance in their shape and sizes, bacteria and archaea were earlier classified as one but on discovery of their metabolic and biochemical differences, it was determined that they had different evolution histories. The bacillus falls under the nonlipophilic fermentative bacteria in classification. Structurally, it possesses cell membranes formed from a combination of the hydroxyl group and fatty acids. Unlike the bacteria, the archaea has linkages that contain ether bonds (Willey, 2003). The cell wall of C.diphtheriae is made up of peptidoglycan bonds which is a great variance from that of the archaea which contains no such bonds. Another major cutting edge factor that classifies C.diphtheriae…...

Luminous Bacterium Vibrio Fischeri Vibrio
Pages: 6 Words: 2011

The chemical was found to turn on quorum sensing in V. fischeri, whereas it inhibited pathogen Pseudomonas aeruginosa. Also, the slow-release was shown to be far more effective than by applying the chemical directly as an aqueous solution. Since quorum sensing is also important for pathogen establishment this application could be important for inhibiting pathogenic bacteria from colonization of internal medical devices.
In summary, the V. fischeri and squid symbiotic relationship is an important model host-bacteria system. Aspects of colonization of host-symbiont and host-pathogen have been shown, using the V. fisheri and squid model, to be the same. Therefore, understanding the mechanism and complex transcriptional regulatory systems of V. fischeri could lead to potential new therapies and pharmaceutical applications. Likewise, understanding the environmental factors necessary for successful host-bacteria interactions could lead to novel drug targets. In addition to being important in understanding other harmful host-bacteria relationships the V. fischeri and…...

Management of Immunocompromised Patients
In beginning I writer specific nursing assignment. The Question: 2000 Words While clinical placement asked prepare a single room an admission. The patient requiring admission isolation room immunocompromised.

Immunocompromised patients usually require isolation in order to prevent them from becoming infected with infections from other patients which is known as protective isolation. For the immunocompromised patients, their immune system is unable to fight the infectious diseases. There are many diseases or conditions that lead to immunodeficiency in patients.

One is AIDS (acquired immunodeficiency syndrome). The pathophysiology of AIDS starts when the person's CD4+ T cell count begins to decrease as the disease kills these cells. This is HIV-induced cell lysis where the virus enters the CD4+ cells where it inserts its genetic information to the cell nucleus thus taking over the cell and replicating itself. The virus then mutates extremely rapidly thus making it more and more difficult for…...
