Pseudomonas Aeruginosa Essay -- Botany

Pseudomonas aeruginosa is a Gram-negative aerobic bacterium with a rod shape, belonging to the family Pseudomonadadaceae. Pseudomonas aeruginosa is a free living bacterium commonly found in soil, water, and occasionally on the surfaces of plants and the normal flora of animals (Todar, 2008). It acts as an opportunistic pathogen of humans and will infect almost any compromised tissue causing a range of infections from urinary tract infections, bacteremia, and a variety of systemic infections; especially in those with a compromised immune system (Todar, 2008). The infections caused by Pseudomonas aeruginosa can be frustrating to clinicians because of its resistance to antibiotics. Primarily a nosocomial pathogen, it is known to cause ten percent of hospital-acquired infections (Todar, 2008). Pseudomonas aeruginosa is motile by means of a single polar flagellum used for adhesion and invasion during bacterial infection. Pseudomonas aeruginosa is omnipresent in soil and water or surfaces that come in contact with soil or water; as well as all manmade reservoirs. Its metabolism is always respiratory, but it will grow in the absence of oxygen if nitrous oxide is available to work as a respiratory electron acceptor (Todar, 2008). Its most favorable temperature for growth is thirty-seven degrees Celsius, but it can grow in temperatures as high as forty-two degrees (Medscape, 2009). In nature, Pseudomonas is a fast-swimming hearty bacterium because of its flagellum (Medscape, 2009). It has very simple nutritional requirements, making it easy to thrive almost anywhere. Organic growth factors are not required, yet it can use over seventy-five organic compounds for growth (Todar, 2008). Pseudomonas aeruginosa is tolerant of many conditio... ...the best way to treat an infection caused by Pseudomonas aeruginosa, but it cannot always be prevented. Most strains are susceptible to gentamicin, tobramycin, and fluoroquinolins, but resistant strands have emerged making treatment virtually impossible (Todar, 2008).

Importance of Sports and Games

Education without activities is always incomplete. A child may mug up the history textbook, but for how long? May be until the last bell of exams but if it gets a bit of interactive touch, then the same student may have such a memorization and understanding that he will not only just forget it ever in his life but also implement it in his life with an equal degree of effectiveness. The clear-cut inference is this that if the education is the car then sports and activities are the keys to drive on towards the success! Yesterday I read a newspaper report which showed the tendency oildren to remain away from all sorts of physical activities.I felt really sorry to hear this. Friends if you think that if Newton had just studied days and nights to bring to the world his greatest achievement. Importance Of Sports The importance of sports in the life of a young student is invaluable and goes much further than the basic answer that â€Å"it keeps kids off the streets. † It does in fact keep kids off the streets, but it also instills lessons that are essential in the life of a student athlete. Sports play a pivotal role in the makeup of a young athlete, especially in the middle school to high school years where student athletes are much more mature and mentally developed.Where else can a young, impressionable youth learn values like discipline, responsibility, self confidence, sacrifice, and accountability? Television, which may be the most influential tool in the lives of young adults, does not show enough of these qualities, nor is it on the Internet, or radio. Rather it is up to the parents, teachers, sports teams, clubs, and after school programs to help mold, develop, and instill these qualities into the lives of student athletes.

Discovery Essay on Away Michael Gow - 923 Words

â€Å"To discover is to gain sight or knowledge of something.† How have ideas about discovery been shown in Away and The Book Thief Discovery allows main characters to gain sight or knowledge into themselves and others. This is evident in Michael Gow’s Away, as seen through the characters of Gwen, Coral and Tom. The three gain sight and knowledge into their lives through the different perceptions and ideas of discovery. Similarly, in The Book Thief, Liesel gains sight and knowledge into the world around her, with the help of books which allow her to become educated about the immoral acts that are†¦show more content†¦As a result of Gwen’s upbringing in the depression, she consequently places a false value upon materialistic goods. At the night of the play, Gwen asks Meg â€Å"Why did you have to do Shakespeare for? We couldn’t see a blessed thing†. Through her dialogue in relation to the Shakespearean allusion, this displays that Gwen resis ts the emotional depth that Shakespeare represents, and that she is metaphorically blind. Once Gwen discovers the knowledge about Tom’s condition, she gains sight, and is no longer metaphorically blind to reality. Through her sight, she realizes that family is more important than placing a false value on materialistic goods. This idea of discovery has been explored through relationships and events which significantly impacted on her new found knowledge and sight. Tom, the agent for change gains sight and knowledge into the acceptance of his impending death. The opening of the play starts with the ending of A Midsummer Night’s Dream where Tom as Puck says â€Å"Gentles, do not reprehend. If you pardon, we will mend.† This foreshadows Tom’s healing role in the play. Although Tom seems to be the character in the least need of a discovery, he still gains sight into the reality of his condition and knowledge that he needs to accept this.
