How Antibotic Resistance occurs and Prevention of Resistance Essay

How Antibotic Resistance occurs and Prevention of Resistance - Essay Example The situation is so serious that some medical experts have suggested the fact that the medical field might again fall into the dark period where there were no antibiotics (Davies & Davies 2010). Antibiotic resistance is a serious medical issue that is led to by many reasons and many drug resistance strains have of bacteria have resulted for example the strains of Neisseria gonorrhea. Antibiotic resistance has evolved owing to many underlying causes. Human activities have been a major cause. These include the utilization of antibiotics regularly for agricultural purposes and the disposing of wastes containing a high quantity of the antibiotics. Treatment plans for wastewater are also seen to have high quantities of genes and resistant bacteria. The incorrect use of antibiotics is another reason for the formation of drug resistant strains of bacteria. Genetic changes are the most common reason for the creation of resistance strains. The most common mutations are noted in the genes that code for the ÃŽ ²-lactamase enzymes. Intrinsic resistance is another process which results in resistant bacterial strains. This results as the genetic code of certain bacteria already possesses the capability of forming new resistant strains. Certain bacteria already possess the ability of preventing the functioning of antibiotics and hence this is also a cause of antibiotic resista nce (Davies & Davies 2010). Neisseria gonorrhea is a common bacterial agent which has had many genetic changes that have resulted in making many antibiotics ineffective in its treatment. Sulfonamides were considered to be the best treatment for gonorrhea but after a short period of their usage resistant strains of this bacteria came forward. Gonococcus bacteria have the capability to adapt to changes in their surrounding and undergo changes which is the reason for the

Strategy Of Oil Spill Disaster In The Gulf Of Mexico Essay

Strategy Of Oil Spill Disaster In The Gulf Of Mexico - Essay Example In the month of April, the year 2010, a platform for deepwater drilling in the Gulf, located fifty miles from the Louisiana coast capsized and sank due to an explosion. Several attempts to seal the top the well continued to be futile necessitating huge volumes of oil to spill and spread to the shores. The spills reached as far as the marshes Louisiana. The company that was behind the oil-drilling venture was the British Petroleum. The effects of this disaster are tremendous and cut across several sectors ranging from the economy to the biological sustainability. The oil spillage threatened the livelihood of more than four hundred species of wildlife. The sea animals whose lives were most threatened includes tuna, whales, and shrimps together with several species of birds. The land animals most affected by the disaster were the white-tailed deer, gray fox several amphibians like the snapping turtle and the alligator. The economic costs arising from the spillage in the Gulf were huge (The Daily Green 2010, p.1). For instance, by June 2010, the government had paid $ 62 million as compensation claims to 26,500 the residents in the Gulf of Mexico. Additionally, the insurers will likely spend up to $ 1.5 billion in compensation. Close to 12, 000 residents of Louisiana are now jobless due to oil spills in the Gulf (The Daily Green 2010, p.1).

This is not the initial time the British Petroleum industry has had to confront a disaster. A refinery that the company owns in the city of Texas experienced a massive explosion in 2005.
