LOVE (14% Discount) - Essay Example Effect of a microorganism or virulence of a bacterium may be caused by an organism being physically present in the host where it releases toxins to the host directly or its preformed toxins get into another organism’s body system through various routes such ingestion, skin etc. The virulence of microorganisms varies across genus as well as species. In this paper, I am going to describe two bacteria, explain their ecological niche, and finally compare them. After a thorough evaluation of bacteria I have rested on Escherichia coli and Lactobacillus bulgaricus. The reason for selecting the two organisms is that they share a common feature of exhibiting a rectangular shape but their behaviors are totally different. Their similarities and differences are expounded below. Lactobacillus bulgaricus’ is a non pathogenic organism. It occurs in its natural environment and its ecological niche is where there is its requirements for growth are provided especially in dairy products that contain lactose. It is chemoorganotrophic meaning that it must obtain energy and carbon from organic compounds. It is a rod shaped and the rods join end to end to form a filamentous structure that are extensively long. This bacterium is a gram positive facultative anaerobe. Based on this fact, Lactobacillus bulgaricus can be homofermenative or heterofermentative. When it comes to motion, the bacterium is non motile because it does not possess locomotion. When conditions become unfavorable this particular bacterium does not form a spore. According to Guchte (2006) its size based on its shape ranges between 0.5-0.8 x 2.0-9.0mm. For this bacterium to grow it requires a medium whose pH ranges between 4.6 -5.4 (Guchte, 2006). The fact that it can only hydrolyse lactose sugar makes it quite important to food industry because of its by-products. When

People’s emotions and characters are always defined by those they are close to and are directly affected by this closeness; this is why Eugene O’Neill’s play A Long Day’s Journey into the Night portrays an idea of naturalism that flows through people within a family unit throughout their lives (Brantley: New York Times June 21, 2012). Realism is mainly depicted by naturalism. Naturalism dictates the chains of events, occasions, lives and the people at large. What shape the human character are the environment, social conditions, and the hereditary factors; that binds families. A critical analysis of the play vividly shows that it is an idea of naturalism on how family influences the lives of its members in a manner that is inevitable. Naturalism and materialism in the context of different scopes of life and its pre-determinants are basis of the Marxist theory. Families are the units that greatly support one another throughout life. People face many challenges in life and needs come in different forms. The play exhibits the essence of naturalism, Marxism and the need of family; which are evidenced by the constant disturbing realities shown in the play right from the start all the way to the end. At the beginning, James’s wife, Mary, is being treated from morphine addiction and at some point tends to abandon the habit, and being restored into the normal life. However, this is only short-lived. It is clear that the stress in the family is contributing to the scenarios (Brantley: New York Times, May 7, 2003). Edmund’s bad health is distressing the family and James and Jamie’s alcoholism are apparently contributing to Mary’s morphine addiction even if she tries to avoid it. This is a clear example of how the negative elements in a family negatively
