Many people get viruses, prions, and bacteria confused in multiple ways. However, these are different in several aspects, and once informed about them, people should no longer get them mixed up. For example, the most important and most unique differences between bacteria, prions, and viruses is that bacteria is a living organism, prions are not living organisms, and the debate regarding the living status of viruses has been, and still is, running on without the slightest sight of a resolution. Other pieces of evidence differentiating these is the way they reproduce, the way that they look, as in their shape and size, and the diseases that they cause and can help cure. In the past fifty years medical and technological information has increased majorly, revealing more knowledge and insight as to the similarities and differences between viruses, bacteria, and prions.
The first topic of discussion is the different structure types and sizes of these different organisms. Bacterium can appear in a few different shapes when you observe it under a microscope. The first of three is a spherical shape. The scientific name assigned to this type of bacteria is coccus (plural: cocci). Coccus is a term that means a berry. Many berries are in the shape of a sphere and this is why scientists designated it this name. Secondly, there are bacteria that exist as a rod shape. These are called bacilli (singular: bacillus), meaning a little stick. Lastly, and most uniquely, there are certain bacteria that are in the form of a spiral. The name given to these is spirillum (plural: spirilla), meaning spiral or coil. As for the way bacteria lives with other bacteria, it can exist on its own, in a pair, diplo-, in a group, staphylo-, or in a chain, strepto-....

Essay on Prions

- Sometimes a scientific discovery shakes the confidence of scientists, making them question whether they truly understand nature's ground rules. That's exactly what prions have done to scientists' understanding of the ground rules for infectiousdiseases. Prions cause diseases,but they aren't viruses or bacteria or fungi or parasites. They are simply proteins, and proteins were never thought to be infectious on their own. Organisms are infectious, proteins are not. Or, at least, they never used to be....   [tags: essays research papers]

- Viruses, Bacteria, Prions Bacteria is essential to humans to not only be able to live, but also to be able to live on Earth. Bacteria is also essential for good health. The typical structure of bacteria includes; cytoplasm, nucleoid, flagella, pili, and a cell wall with a capsid. Bacteria is found in the Large Intestine, where it makes Vitamin K. It also helps provide a taste for yogurt and sourdough bread. Bacteria is used to digest cellulose for animals such as cows, sheep, and goats. Bacteria is prokaryotic, and appears as many different shapes....   [tags: microbiology essential to humanity]

Viruses, Bacteria, and Prions Essay

- Viruses, bacteria, and prions are all quite different, but they all share one commonality: they can all cause disease in humans. All three are also organic, in one way or another. Despite this, only bacteria are properly alive by most definitions. Bacteria are also the most complex, followed by viruses, and then finally, prions. Bacteria As mentioned in the introduction, bacteria are the most complex organizations that will be covered in this paper.

Bacteria, Viruses and Prions Essay

- We’ve all heard of viruses, bacteria and the diseases they can harm us with, but many of us haven’t even heard of prions and most people probably don’t know specific details about viruses or even bacteria for that matter. They’re all very interesting forms of organic matter, though. Bacteria are the only one of the three that are actually considered life forms 100%. The topic of whether or not viruses are to be considered an organism is very debatable in the world of microbiology, because they don’t actually have even a single cell, but they reproduce and have many other things in common with organisms....   [tags: proteins, health, disease]

Essay on Bacteria, Viruses, and Prions: Cell Structure and Reproduction

- Commonly known for causing diseases in humans, bacteria are also a valuable key in a healthy lifestyle and other aspects of life. From manufacturing Vitamin K to giving yogurt its tangy taste, bacteria come in many shapes, sizes and forms. Bacteria lack a well-defined nuclei and membrane-bound organelles, and with chromosomes containing a single closed circle of DNA, they are categorized as Prokaryotes. Each bacterial cell typically has the same structures that have a certain function within the cell....   [tags: biology, biochemestry]

Biological Agents Which Can Cause Infectious Diseases Essay

- 1. There exists seven distinct categories of biological agents which can cause infectious diseases. These agents are: a. Virus. They have an outer coat made of protein and have DNA or RNA core. They can only reproduce and grow in living cells. An example of a disease caused by virus is influenza- a respiratory illness that leads to the development of pneumonia. b. Bacteria. These are single-celled organisms with no nucleus. An example of a disease caused by these organisms is tuberculosis; a well-known chronic lung disease....   [tags: Bacteria, Infectious disease, Infection]

Essay on Bacteria and Viruses

- Bacteria are unicellular organisms called prokaryotes. Viruses are pieces of biomolecules that cannot reproduce independently. Both groups may be pathogens, or may be beneficial- sometimes, the same species or variety may be both, depending on circumstances (Starr, C., and Taggart, R., 2004.) Throughout history, pathogens and more helpful species have played vital roles in the development of humanity as a species and of the human social arrangement. Prokaryotes are divided into eubacteria and archaebacteria....   [tags: Health]

Essay on Prions

- Prions Prions have been a mistery for scientists from the day they where discovered. Prions act like viruses but they are not. Their structure and chemistry are unknown. They are believed to be proteins but that is yet to be completely proved. Prion stands for “proteinaceous infectious particles”. Prions are known to cause many diseases involved with nervous systems like the brain. They are the ones that cause the well known “ mad cow ” disesase in Britain and “scrapie” for animals. For humans they are known to cause a rare disease in Papua New Guinea called Kuru ( or “laughing death”) which striked only the cannibals in the Highlander tribes....   [tags: essays research papers]
