Staphylococcus Aureus Research Paper

A Food Poisoning bacteria – Staphylococcus aureus
Introduction
Microbe which sizes form 0.2µm to 200µm includes bacteria, algae, fungi, and protozoa. It is such a tiny organism that we cannot see it with naked eyes (Eric S. MacDicken, 1999). Nevertheless, microorganism is influential for us, without it we cannot eat or even breathe, in fact, they are our invisible companions in our lives. Our living environment is surrounded by microbes so we are keeping in touch with them. Many people believe that all microbes are harmful for us but it is false. Some microbes are not only advantageous to our health but also beneficial to our economy (Elizabeth Brown, 2014). Whereas some microorganisms are toxic for us such as Staphylococcus aureu (S. aureus). …show more content…
aureus, it breeds asexually by binary fission. Binary fission is a process that parent cell copies its genetic material then divide and transform into two daughter cells (G. Klotz-Engmann, 1989). There are four stages in binary fission (figure 9):
1. Cell doubles its biomass – chromosome replicates, cell wall, cell membrane and cell organelle start to synthesis and cell shape elongated.
2. Replication of the DNA in the cell – replicated DNA move into the contrary side by attaching to growing membrane
3. Septum Formation – Septum is formed to divide the cell
4. Cytokinesis – Division of the cell into two daughter cells, each containing a single copy of the chromosome
Binary fission (figure …show more content…
We cannot look down on them since they can help us on many aspects. We can see the wisdom of S. aureus, they evolved different characteristics to adapt to the environment. Although they are low animal, they can change their body structure easily that human or other high animal cannot do. Our evolution demands a long time (Dobzhansky, T. G., 1962), maybe microbe is better than us in term of evolution. As the highest animals, human should learn how to respect and appreciate other animals, respect and appreciate their simple and small. Because of human’s high intelligence quotient, sometimes, selfishness occupies our mind, we ever think of ourselves but not other creatures. In recent years, human keeps destroying the habitat of other animals for economic benefits or somethings making species extinct. Frankly, in the world, all kind of organisms should have equal right to enjoy the resources provided by
