Bacteria Essay

manufacturers, thinking infectious diseases were essentially conquered, cut back severely on searching for additional antibiotics” (Levy). Unknowingly, people all over the world are promoting the reproduction and spread of multiple-drug resistant bacteria and viruses. Every continent in the world is connected by easily accessible travel which makes infection effortless. There are numerous amounts of methods can slow down this process and keep people healthy. If the problem is ignored any longer,…

lab, students will be taking the pGLO gene, which makes the protein Green Fluorescent Protein (GFP), commonly found in a species of jellyfish, which glow (N.d., p. 32). Theoretically, when the pGLO gene is inserted into the E. coli bacteria, then the E. coli bacteria will also…

staining for identifying a Gram positive bacteria – Please explain your answer? The ideal staining for identifying a Gram positive bacteria is brown-brenn gram stain is preferred to detect the positive bacteria. 13. What is the ideal staining for identifying a Gram negative bacteria – Please explain your answer? The ideal staining for identifying a Gram negative bacteria is the brown-brenn modification is superior for the detection of the gram negative bacteria. 14. How does…

that stood out was that the news article used the statement from Dr. Timothy Lu, “There’s a symbiotic relationship between the two sides, human and bacteria” to emphasize what the point of relating gut bacteria and humans was, while the journal article just used more scientific facts and terms to talk about more specific conclusions between gut bacteria and social behavior. Obviously, the journal article was narrower in its discussion while the news article used some other outside sources also…

quite different. These drugs have different effects on the bacteria they are being used against. Rifampicin is a bactericidal drug and chloramphenicol is bacteriostatic. Bactericidal drugs interfere with the bacteria to such an extent that the bacteria die. They not only prevent new cells from growing but also cause a crucial aspect of the cell division to stop operating which leads to death. Bacteriostatic drugs however only prevent new bacteria from growing and dividing. When used for a long…

and even purposes. The reasons for this hypothesis is because, as the bacterium were being observed, it was recorded how one is uniquely different than the other. Each structure allows the bacterium to carry out different functions. However, some bacteria may occur more than once, or have a trait in common relating to another bacterium. Additionally, under a microscope, each bacterium tested either positive or negative with a gram stain test. As shown in Table 1, of Experiment A, the…

as well as many mucosal surfaces. They are composed of mainly bacteria, fungi, and protozoa. These commensal microorganisms live in the human body in symbiosis. Microbiota play a functional role in the health and disease of an individual. Roughly there are around 1012 bacteria found on the skin, primarily staphylococci and corynebacteria, and 1010 found in the mouth, primarily, streptococci, lactobacilli.1 But the majority of the bacteria, more than 400 species are found in the gut with…

HLTIN301C Assignment Q5a+b need answering 1. List and give a brief description of the four main groups of microorganisms. • Bacteria – A single celled organism that thrives in diverse environments. There are 5 groups that bacteria can be divided into (according to shape): bacilli, cocci, filamentous, spirilla and vibrio. Some are beneficially good for the body and others can be parasitic and produce toxins that can cause disease or death. • Fungi – A single celled or multicellular organism…

Escherichia Coli, or E. Coli, are a large and diverse colony of bacteria within the fecal coliforms group – a group of closely related bacterial genera that share the ability to metabolize sugar lactose, producing acids and gas as byproducts – found living harmlessly in warm-blooded organisms’ intestines, the environment, or in various foods (2006). Unfortunately, some forms of E. Coli bacteria are pathogenic, in which the bacteria has developed the ability to cause the disease of the urinary,…

the evolutionary order is the typical bacteria, which I viewed at a 1000 magnification. These bacteria can be found in the Eubacteria domain and kingdom. The bacteria in my sample were coccus, which means that the bacterium has a round shape, and this type of bacteria is one of the simplest forms of bacteria. These cells are also prokaryotic because they do not have a nucleus and they are heterotrophic because they do not produce their own food. These bacteria are unicellular, however they work…
