Plasmids are extra chromosomal DNA within some bacteria that exist as circular structures. Although they are not essential for survival of the bacterium, they often do confer many environment advantages such as antibiotic resistance. One bacteria of interest is E. coli, a gram-negative organism that is part of normal human gut flora. Some strains of E. coli are pathologic to humans, however some strains are beneficial. For example, one strain produces vitamin K, an essential nutrient. In this…
“Mommy, I don’t feel well!” Instantaneously after hearing her child’s complaints of feeling ill, the concerned mother rushes her child to the nearest pediatrician in order for her child to receive the finest antibiotics. This magical medicine results in the sick patient miraculously feeling better in a relatively short amount of time. As a whole, society views antibiotics as life-saving measures, which they most certainly can be, as antibiotics effectively treat diseases that previously killed…
are considered to be plants which have been modified using genetic engineering to alter their DNA. This is used to introduce a new trait to the plant which doesn’t occur naturally such as resistance to certain diseases, insects, environmental conditions, decreases the likelihood of spoiling, increases resistance to herbicides and/or pesticides, or improve the overall crop. Unlike cross fertilization process, genes that have been genetically modified are inserted directly into the DNA of the…
fittingly when insulin is available. Dissimilar to type 1 diabetes, the insulin resistance is for the most part "post-receptor", significance it is an issue with the cells that react to insulin instead of an issue with creation of insulin (Vijan, 2010). Since sugar is not getting into the tissues, strangely elevated amounts of sugar develop in the blood, which is called hyperglycemia. Numerous individuals with insulin resistance have hyperglycemia and high blood insulin levels in the meantime.…
bacterial based diseases. Antibiotics have increased the longetivity of people 's lives around the world; it 's now a rarity to hear of people dying of bacterial infections in modern world. Recently we have seen certain types of bacteria develop resistance to antibiotics, labelled 'the superbugs '. We now a see the emergence of diseases that were once a thing of the past, sparking a worldwide panic. In 1929, microbiologist Alexander Fleming discovered penicillin, a naturally growing substance…
When strolling through the grocery store gathering ingredients for dinner, it is highly unlikely that superbugs are on the shopping list, but many Americans are bringing them home unknowingly. Superbugs, or antibiotic resistant bacteria, are becoming a major public health threat in the United States. Certain varieties of these antibiotic resistant bacteria can be found in our commercialized meat products, such as chicken, beef, and pork, and even on our Bugs, fried in Thailand by Paul Esson…
Why is there such tremendous resistance from the public to accept GMOs? The media can be partially to blame. With fallacious portrayals of the mechanisms and effects of genetic modification, the media has an indelible rhetorical skill every scientist envies. By consistently reporting…
team’s findings, it becomes more important to seek global regulation of the use of antibiotics in food production, in order to minimize the evolution of these superbugs. Global regulation could prove effective in reducing the rate of antibacterial resistance, but another effect of these regulations could be a net loss in the food production of the Earth, as more animals would be lost to infections. Another possible means for government intervention, would be the creation of programs to further…
The article explains the veterinarians, who prescribe the antibiotics, stand point on the topic. I plan on also using statistics about antibiotics being used as growth promoters, and statistics about deaths regarding bacteria that have built up resistance to the antibiotics. This is primarily seen as the result of using antibiotics in the livestock…
to their causes. Whether one believes in the cause or not the violence wielded as a tool for reform is that of a Neanderthal mindset and not one of a civilized educated society. Civil disobedience by its very definition is that of a non-violent resistance to the demands, laws, or treatments of a government body. While violence may be construed to more of a civil rebellion, there is some debate as to whether all civil disobedience does in fact need to be nonviolent.…
