Vancomycin - Essay Example New antibiotics were introduced to fight the ever changing and more resistant strains. Vancomycin, the antibiotic of last resort, has been used to fight infections when all other drugs fail, but has recently met its match with strains that have become resistant to this last line of defense. Methicillin-resistant Staphylococcus aureus (MRSA) is a highly virulent infection that has become resistant to most antibiotics. MRSA is a bacteria that is normally found in healthy people and usually is merely a passive bystander. However, it can cause skin infections and can occasionally be quite severe. By 1987 hospitals in Europe were reporting the first cases of vancomycin resistant Enterococcus. Between 1987 and 1993 the problem was escalating and had resulted in a 20 fold increase in the number of cases of vancomycin resistant enterococcus reported by intensive care units in hospitals in the United States. It was reported in 1992 that the vancomycin resistant gene from Enterococcus had been transferred to Staphylococcus aureus in a laboratory in England. The researchers were alarmed and destroyed the bacteria. According to Dr. Ricki Lewis reporting in the FDA Consumer magazine in 1995, "... bacteria swap resistance genes like teenagers swap T-shirts".

Colonialism in 1880-1900 Essay Example | Topics and Well Written Essays - 750 words

Colonialism in 1880-1900 - Essay Example According to the study the end of the slave trade was an additional main controlling feature towards colonialism. Even though the trade of humans was â€Å"legislated against, many of the Africans and Arabs continued the practice, particularly inland, where the European influence was less concentrated''. Those Europeans dedicated to eliminating this practice were compelled to stay at these internal places with the intention of taking direct as well as instant action. Obviously, slavery was a profitable trade and its elimination meant that substitute trade and business required to be started all over Africa. Therefore, colonialists as well came into the continent to discover different trading means, types of transportation and additional resources. They were required to teach the neighboring societies regarding commercial growth with the intention of maximizing the productivity of the countries. During the colonial phase, the perception of particular indigenous people in the African continent attained broader recognition, even though not without debate. From this paper it is clear that the extremely diverse and abundant ethnic groups, which consisted of most contemporary, self-governing African states, had within them different individuals whose condition, civilizations and pastoralist or huntsman life wee usually marginalized and set separately from the leading political as well as financial structures of the country. From the last part of 20th century, these people have increasingly wanted identification of their constitutional rights as separate indigenous people, within both nationwide and worldwide perspectives. Given the widespread and complex account of human immigration inside Africa, being the earliest people within a territory is not a required condition for recognition as an indigenous people. To a certain extent, indigenous uniqueness communicates more to a set of attributes and practices than ‘priority of arrival’. For instance, quite a lot of populations of nomadic people occupy regions within which they a rrived somewhat lately. Their declaration to indigenous standing is founded on their marginalization as nomadic people in regions and countries ruled by inactive farming people. Early African reaction to European invasion into Africa during the last part of 19th century was not standardized. A small number of groups that had experienced long-term combat or slave raiding provided a doubtful welcome to European existence within their constituencies in anticipation that there would be harmony. Other groups vigorously opposed the arrival of European political power. On the other hand, a number of people had no initial response towards colonialism. This was due to the fact that the early years’ colonialism had slight impact on the lives of several rural African people. These circumstances transformed as the impact of colonialism became more extensive as well as deep during the mid of the 20th century. By the last part of World War I, the majority of Africa had been successfully co lonized. European colonialists had managed to control the attempts by Africans to defend against the organization of colonial regulation. The subsequent two decades were known as the inter war years by historians and was somewhat calm within colonial Africa.
