The Conspirator - Essay Example This paper discusses the conspirators involved in this plot in general and the role of Mary Suratt in particular. Abraham Lincoln was assassinated on April 14, 1865. He was the first president in American history who faced assassination. Lincoln was assassinated at a time when American civil war was in its closing periods. At the time of assassination, Lincoln was watching a play at Fords Theatre in Washington, along with his wife. The major conspirator of Lincoln’s assassination was a stage actor called John Wilkes Booth. He has planned this murder in company of Lewis Paine, George Atzerodt, David Herold, and Mary Surratt. Actually, the conspirators planned to murder the secretary of state and the vice president along with Lincoln. Pain and Herold had assigned the duty of killing the secretary of states while George Atzerodt had the duty of killing the vice president. However, they succeeded in murdering Lincoln alone even though Paine shot the secretary of state. The major objective of this mass murder attempt was to destabilize the American government which took serious actions to end civil war and also to end racial discrimination. All the conspirators were arrested even though Booth suffered serious injury while attempting to escape and later died in the police custody. All the other four conspirators were hanged. Mary Suratt was an American boarding house owner who was accused for participating in Lincoln’s murder conspiracy. She was hanged and became the first woman in American history to suffer execution Mary Suratt’s involvement in the conspiracy was unbelievable to the people who know her. She was highly religious in nature and was not at all a woman of aggressive nature or intend. She was simple and behaved politely with others. However, her involvement in this conspiracy was proved beyond doubt

Streptococcus pneumoniae - Essay Example They are readily stained with aniline dyes and are Gram positive. The capsule may be demonstrated as a clear halo. They have complex growth requirements and grow only in enriched media. They are aerobes and facultative anaerobes, the optimum temperature being 37Â ºC. On blood agar after incubation for 18 hours, the colonies are small, dome shaped and glistening with an area of green discoloration along them. Some strains that develop abundant capsular material (types 3 and 7) form large mucoid colonies. Under anaerobic conditions, colonies on blood agar are surrounded by a zone of beta hemolysis due to oxygen labile hemolysin O. In liquid media, such as glucose broth, growth occurs as uniform turbidity. Streptoccocus pneumoniae ferment several sugars, forming acid only. Fermentation is tested in Hiss’s serum water or aerum agar slopes. They are bile soluble. Bile solubility is a constant property and hence is of diagnostic importance. Pneumococci are catalase and oxidase nega tive. They are delicate organisms and are readily destroyed by heat and antiseptics. The most important anitigen of pneumococcus is the type specific capsular polysaccharide. Pneumococci isolated from lobar pneumonia were originally classified into 3 types, I, II, and III and a heterogenous group IV. Memebers of Group IV were later classified into types, and 90 different serotypes are recognized. Typing may be carried out by i) agglutination of the cocci with a type specific antiserum; ii) precipitation of the SSS with the specific antiserum; or iii) the capsule swelling reaction described by Neufeld (1902). An abnormal protein (beta globulin) that precipitates with the somatic ‘C’ antigen of the pneumonia, appears in the acute phase sera of cases of pneumonia but disappears during convalescence. On repeated subculture, pneumococci undergo a smooth-to-rough (S-R) variation. The virulence of pneumococci depends on its capsule and the production of called
