The concept of microbiology emerged in the late 1600s when Antonie van Leeuwenhoek first observed bacteria and other microorganisms using a single lens microscope. The microscope manufactured and used by Leeuwenhoek served as a catalyst for the field of microbiology, exposing a whole world of microorganisms. With the utilization of tools like microscopes and methods like ink staining, scientist have been able to step into a seemingly invisible world and note the contribution of microorganisms to human life. These tools and methods have been essential to the discovery that DNA was the macromolecule charged with the transformational ability of genetic information in bacterial cells

...most important macromolecules in all living organisms, was lead by microbiology. Working with and dissecting cells that remain invisible to the naked human eye is one of the main components of microbiology. When scientist analyze Griffith’s experiments they are able to observe the protective capsule surrounding the S-strain cells by embedding the organism in India ink before sectioning it and using an electron microscope (3). This allowed them to actually note the presence of a smooth exterior and the transformational ability of the genetic material. The same techniques were also used to enhance all of the previously mentioned experiments. Electron microscopes and other other innovations from the field of microbiology helped validate the initial findings of these experiments and establish DNA as the macromolecule that facilitates the transfer of genetic information.

- Statement of Purpose The amount of damage that microbes like HIV and Cholera could do to the human body fascinated me, and my curiosity led me to want to learn a lot more about these diseases and others. As an AP biology student, my teachers did go into some detail about how these diseases developed, I kept asking more questions about the molecular basis of how these diseases worked until my teacher would tell me that she did not know. As an idealistic high school student, not only did I want to learn more about how these diseases interacted with the human body, but I also wanted to discover ways of stopping them....

- There are six steps to become a licensed veterinarian. The earning of two degrees’, the courses that are recommended, the extra certifications required to specialize in particular fields, the testing to pass on to the next step to become a licensed veterinarian, the veterinary experience to get on your feet and an idea of what is expected, and lastly, the interview process. Once a student has gone through all six steps, then the student is transitioned into a doctor of veterinary medicine. To become a licensed veterinarian, a student must major in either a science or mathematics degree.... [tags: Medicine, Physician, Medical school]

- Knowledge is power when discussing the classes you have taken in college and how it affects your everyday life. Microbiology is one of those important classes where although for a majority of majors you do not have to take it and therefore will not learn the information discussed in it, other majors such as biology and nursing require you to take it. They will require you to take it because you will encounter some of the information being taught in it in the work field. As a nurse practitioner I have worked in the field with many patients who were diagnosed with Leprosy, Escherichia coli, Salmonella and other bacterial diseases....

- The readers of my paper vary from demographics, it is intended to be read mainly by biology and health students, but it also includes parents of young children from all backgrounds, though they are a secondary audience. Students read my paper so that they a have a grasp on a how their field is applied in the real world and the complications that result of implementing it in a certain fashion. My readers likely understand the fundamentals of how vaccines are supposed to work, and they understand the necessity of being immunized, many if not all would favor having a completely immunized populous, resulting in elimination of diseases....

- Forensic Pathology The forensic field is categorized into many different kinds of specialists or forensics, for example Anatomic Pathology (The morphologic evaluation of tissue removed from living or dead individuals, using the unassisted senses and the microscope) and Clinical Pathology (the evaluation of body fluids by laboratory means). The most important field is forensic pathology. An understanding of DNA analysis and its advantages over other methods of criminal association is considerately more important to the forensic scientist tasked with a murder case, which is why it is the most important....

- BIOL 240: Assignment One 1876: Validation of the germ theory of disease| Robert Koch After conducting studies on Anthrax, Koch published a paper blaming a particular bacteria as the root of the disease, validating germ theory. The validation of germ theory helped pioneer the field of clinical microbiology. By understanding that certain microorganisms cause disease, the community made huge advances in anti-biotics and hygiene. In this course, we study Koch’s postulates, the four criteria that generally need to be fulfilled to conclude that a microorganism is responsible for a disease....
