Antibiotics Are Bacteria And Bacteria

- Stewart, Philip S, (2001) states that antibiotics are elements that are used to kill, or hinder the multiplication and growth of organisms. Especially, these antibiotics are meant to control fungi and bacteria. In this case, the antibiotics that are used in killing bacteria are referred to as bactericidal, and the ones that are used to prevent the multiplication process are bacteriostatic. The primary microbes for antibiotics are bacteria and fungi. These microorganisms are crucial to facilitate the secretion of substances that kill harmful bacteria which confer competition for the limited available nutrients (Southern, P....   [tags: Bacteria, Antibiotic resistance, Microorganism]

Why The Bacteria Is Resistant Or Sensitive Or Pathogenic Bacteria?

- Introduction We identify bacteria in order to identify whether or not it is good bacteria or pathogenic bacteria. Cultures are run to determine if the bacteria is resistant or sensitive to an antibiotic. The bacteria must be identified and susceptibility test must be performed for the doctor to know the cause and to give the patient the best treatment.

I am very interested in learning my topic because it could help lead to conclusions about how to keep different types of bacteria from spreading over the course of time. This could be a useful experiment because if certain types of harmful bacteria don’t grow as quickly when it is exposed to certain types of music, others scientists could figure out a way to prevent harmful types of bacteria from...   [tags: sound, waves, frequency, health, experiment]

Bacteria reproduce rapidly and exist in any place conducive to their survival. Although their omnipresence is intimidating from a survival standpoint, the vast majority of bacteria are harmless. Those few that are infectious, disease-causing agents are known as pathogens. Despite their negligible size, these organisms can be lethal when they infect living things....   [tags: antibiotics, bacteriophages]

The Anthrax Of The Pneumonia Bacteria

- a. The first experiment conducted by Griffiths, in 1928, used two strains of the pneumonia bacteria each injected into live mice. The 3S strain was found to kill the mouse, while the 2R strain was found to be fought off by the mouse’s immune system. However, when live 2R and dead 3S strains were injected into the same mouse, the dead 3S bacteria strains were brought back to life and the mouse died. This discovery lead to further experimentation done by Avery, Maclead and McCarty. Their experiment separated the live 2R bacteria strain into three individual vials and injecting one type of enzyme into each vial in order to inhibit either the DNA, RNA or protein of the live 2R bacteria strain....   [tags: DNA, RNA, Virus, Gene]

Understanding Viruses, Bacteria, and Prions

- 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....   [tags: Molecular Expressions Cell Biology]
