Salmonella And Common Food Poisoning Biology Essay

Salmonella And Common Food Poisoning Biology Essay Food poisoning is a common problem that affects millions of people in the United States and throughout the world. Food poisoning can cause distressing and sometimes life threatening problems in humans. People that have eaten contaminated food may be symptom-free or have symptoms ranging from intestinal discomfort to severe dehydration and bloody diarrhea. The following bacteria can cause food poisoning; Campylobacter, Shigella, E.Coli, and Salmonella. The Salmonella family contains over 2,300 serotypes of bacteria. A serotype is a group of microorganism, viruses, and cells classified together based on their cell surface antigens. Salmonella is a Gram-negative, rod-shaped, flagellated and motile bacterium. Salmonella is found in the gastrointestinal tract of fish, turtles, snakes, lizards, gerbils, hamsters, other rodents and humans. Infection can also be spread from person-to -person. Salmonellosis is a zoonotic disease that can spread from animals to humans. Salmonellosis can be spread by eating uncooked pork, chicken, beef, and fish. Salmonellosis can also be spread by eating contaminated food with Salmonella. Symptoms are bloody or watery diarrhea, stomach cramps, throwing-up, fever, head-ache, chills, sweats, fatigue, and a lack of appetite. If the infection is severe the individual might be given antibiotics. The risks of Salmonellosis are the loss of body fluids, dehydration, shock, and death. Remedies for Salmonellosis depe nd on symptoms. Remedies are antibiotics, rest, eating a bland diet, and drinking plenty of fluids. There are three high risk groups: infants, people above the age of 60, and people with compromised immune systems. Salmonella bacteria can also cause Typhoid Fever. Typhoid Fever can be cause by two types of Salmonella bacteria: Salmonella typhi bacteria and Salmonella paratyphi. Typhoid Fever is contracted by the ingestion of the Salmonella bacteria in contaminated food or water. Patients with acute illness can contaminate the surrounding water supply though stool. The stool contains high concentration bacteria. Patients can be classified as Long-Term Carriers if they have a mild infection and it go unrecognized. The bacteria replicates in the gallbladder, bile ducts, or liver and passes into the bowel. The bacteria can survive for weeks in water or dried sewage. Symptoms of Typhoid Fever are high temperature, chest discomfort, abdomen discomfort, headaches, lethargy, poor appetite, ad diarrhea. Typhoid Fever is determined through a stool culture. Typhoid Fever is treated with Antibiotics. There are several scientists doing research on the Salmonella bacteria. There are a series of experiments that are being conducted abroad the International Spaceship that may lead to vaccine against Salmonellosis from Salmonella bacteria. Scientists at the USDA Agricultural Research Service have developed a poultry vaccine for some strains of Salmonella in poultry. The study of how Salmonella contaminates powder infant formula has helped them to create quality assurance procedures, to help prevent contamination of Powder Infant Formula. Scientists are trying to use Salmonella as remedy for hypoxia to help the in treatment of cancer. There are a group of scientists in Morocco that did a study on food samples from Morocco to determine if the food they were eating contained Salmonella. There are a series of experiments that are being conducted abroad the International Space that may lead to vaccine against Salmonellosis from Salmonella bacteria. Dr. Cheryl Nickerson has produced studies that have shown that Salmonella becomes more virulent in weightlessness environment. Salmonellas virulence can be controlled like an on and off switch. NASA started these studies because they were concerned about their astronauts being more susceptible to food poisoning due to their weakened immune systems. Weakened immune systems are due to microgravity. Researchers discovered that microgravity changes Salmonella. The scientists can use this information from space on Earth because the environment inside the intestines is similar to the weightlessness in space. Another Scientist, Professor Timothy Hammond, is pursuing a vaccine based on the genetic changes seen in the space-borne bacteria. There are a series of experiments that are being conducted abroad the International Space that may lead to vaccine against Salmonellosis from Salmonella bacteria. (Klotz, 2009) Scientists at the USDA Agricultural Research Service developed a poultry vaccine to reduce the spread Salmonella enteritidis (S.enteritis) infection among flocks. S.enteritis is a serotype of Salmonella .This current epidemic is caused by egg-borne Salmonellosis. Egg-Borne Salmonellosis is caused to intact and disinfected grade A eggs because S.enteritidis infects the ovaries silently. This contaminates the hens eggs. The vaccine reduces shedding ten to forty percent more effectively than the three commercial vaccines that are currently being used. The vaccine reduces the amount of S.enteritidis that is located in the birds digestive tract that helps eliminate the pathogen shedding in the birds feces. The vaccine also eliminates the pathogen invasion of the birds internal organs. The vaccine is an experimental oil emulsion vaccine. This vaccine is different from commercial preparations because it increases specific levels of antibodies in the digestive tract which reduces the Salmone lla in the hens intestinal tract and prevents infection of eggs and disease of transmission. In this research study, the vaccine was administered to the birds subcutaneously in two doses four to six weeks apart before exposing the birds to S.enteritidis. Researchers performed strict measures to ensure that there are no other pathogens were present in the hens before and during the investigation. In the 1970s, meticulous procedures for cleaning and inspecting eggs were implemented to reduce Salmonellosis. Salmonellosis is caused by the external fecal contamination of egg shells. S.enteritidis became a public health concern in the 1980s. The pathogen invades poultry which can cause harm to the reproductive organs that can lead to contamination of the eggs. In the 1990s, scientists started to develop poultry vaccines against S.enteritidis. Currently, twenty-five million doses of S.enteritidis vaccine are used annually. (Smith, 2006) Powdered Infant Formula (PIF) is not a sterile product and may be contaminated with pathogens that can cause serious illness in infants (children aged

Gender Role Reevaluation in Boys and Girls by Alice Munro Essay

Gender Role Reevaluation in Boys and Girls      Ã‚   Recent history boldly notes the protests and political unrest surrounding the Vietnam Conflict during the 1960s and 70s. However, equally important in this era are the women who pushed for gender role reevaluation and publicly rebelled against the established social norm of a woman's "place." Although Alice Munro may not have been burning her bra on the courthouse steps, threads of a feminist influence can be found in "Boys and Girls." Munro's main character, a girl probably modeled after Munro's own childhood experiences on an Ontario farm, faces her awakening body and the challenge of developing her social identity in a man's world. "The girl," an unnamed character, acts as a universal symbol for the initiation of a girl into womanhood. Through first-person narrative, Munro shoes the girl's views of her budding femininity and social identity by describing the girl's conceptions of her parents' work, her parallel to the wild mare Flora, and the "mysterious alte rations" (Munro 474) in her personal nightly stories.      Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   As if to forsake her femininity and forego a life of confinement and housework, the girl reveres her father's work and condemns her mother's duties. The sum of the girl's respect seems to lie with her father, as is evident in her reference to his work outdoors as "ritualistically important" (468). On the other hand, while the girl recognizes that her mother is busy, she still considers her mother's "work in the house [to be] [ ·] endless, dreary and peculiarly depressing" (468). The division between her parents' tasks is especially apparent in the girl's reaction to her mother's presence at the barn. She feels threatened by her... ...hether this quantifies complete acceptance with the girl, however, is not solidified by Munro due to the final sentence: "Maybe it was true" (475).         Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Through opinion, comparison, and imagination Munro details the girl's journey from a rebellious tomboy to a slowly blooming woman. The characteristics so endearing to the girl's developing identity, such as her assistance in Flora's escape and her unwillingness [comment13] to easily submit to the social constraints of life as a woman, also lend themselves to her universality as a representative to initiation to femininity. Munro's own personal views of femininity arguably color this work, "Boys and Girls."    Works Cited Munro, Alice. "Boys and Girls." The Norton Introduction to Literature. Eds. Carl E.

It is how people liberty to express themselves through music in whichever way they prefer. as well as art and what people confront on a daily basis. Furthermore, art and music has change over time and it has influence in the way we dress and dance. It also reflects on violence and drugs. Finally, have an extremely negative impact on the attitudes and behaviors of American youth. Music affects society now in days by influencing teens in the wrong way. For instance, music videos have made a humongous impact on the behavior of teens. Moreover, teens flaunt their bosoms around just because they see it on the videos so they portray the same image thinking that is the style. For example, Adriana, a cousin she dresses something similar to that and her response is that is what is in. Also, the way teens dance through music. For example, the songs Bring it, Donk, Ass by listening to this type of songs they start twerking dancing. In particular, a dance that teases and inappropriately moves. It consists of how you shake your behind. personality my perspectives about those move dances are inhuman. In addition, this type of songs has made an impact on the dances and it has everybody twerking. A dance that consist of shaking hips and bottom and bouncing up and down motion, causing to shake, wobble and jiggle . Another, huge impact would be the song and dance called The Twist it had have a tremendous impact back in the days. many people were against it but some were not. Foremost, John Johnson Jr. â€Å"The Twist† The Los Angeles Times, 2013) states. â€Å"Soon, the fad hopped generations, sweeping up the â€Å"Mad Men† set of swinging company men and their hip-shaking wives.

Death Of A Salesman, American Dream essays

Death Of A Salesman, American Dream essays After reading Death of a Salesman by Arthur Miller, I notice a major difference can be noticed between my vision of the American dream, and the Loman familys vision of the American dream. To mean the American dream is to decided on your own what you want to do for a living when you are older, and how you want to go about getting there. There are many roads you can take to get to your goals. You can go to college if you desire to, or if your goals and standards are set lower, you can achieve them without college. The choice on how you want to live your own American dream is limitless in my eyes. In my opinion the Loman family has a terrible view of the American dream, and will never be able to achieve true success. The Loman family lives in more of a dream world than reality. They often sugar-coat their lives and make things seem much better than they are instead of actually facing lifes hardships and dealing with them. The entire Loman family does not see life for what it really is, they see life on how they wish it was. Instead of trying to gain their desired lifestyle, they pretend they already have it. Willy Lomans imagination is much larger than his sales skills, which leads to him getting pay cuts and eventually leads to him getting let go from his company. Willys sons Happy and Biff serve as clueless children who live through their fathers lies and false lifestyle. Willys wife Linda serves as a loyal wife who stands by her husband and lives in his dream world. Through out the play I believe Arthur Miller shows many examples of the American dream, but none of them are of the nuclear Loman family. In the beginning of the story a boy named Bernard (neighbor) states that Biff needs to study with him today for the Regents exam that their class would be taking next week. Bernard also stated the results will determine who gets college scholarship. After hearing this Willy...

Norms and Values Essay Essays

Norms and Values Essay Essays Norms and Values Essay Essay Norms and Values Essay Essay Beginning of Life Culture is an acquired style of living. At birth children do not have any knowledge of their cultures nor do they have any influence on which culture they can emulate. The process through which a person acquires certain values and norms is called socialization. At the beginning of ones life, the major influences on the behaviors, conceptions, and values of infants are their immediate social circles. Family and friends often make for the primary influences of individuals. Another important influence is the cultural context in which socialization occurs. The norms and values that are in India may not be the same as how people are socialized in Canada. Cultural diversity often influences the socialization (Kallivayalil 535-559). Looking at the differences in the socialization process in India and Canada can give important insight into the norms and values of both societies. Socialization pushes people towards an ideology or philosophy that governs social and cultural life (Kallivayalil 535-559). In India, there are many different ethnicities. This phenomenon, therefore, complicates the socialization process of the country. For instance, Yanomamo Indian boys are brought up to be aggressive and thought. They are taught to embrace violence and overwhelming emotions. For the most part, socialization is often culturally motivated in India, compared to European and Western Cultures. The family unit is an important social and political unit. In India, a lot of families practice joint living with the extended family (Kallivayalil 535-559). The mother is the nurturer while the father represents the bread winner of the family. In Indian culture, males are permissive, and females are meant to be submissive. The respect for elders also makes important competency for these students. The gender lines in India are given priority in nurturing children. For instance, theyre taught how they ought to behave and even have arranged marriage. In fact, the filing of divorce is not taken well by the society. Western cultures bring up their children in a different method. For one, the value for culture is limited given the diverse mix of people. It is difficult to find parents and peers whose cultural and social belief coincide. For this reason, one of the approaches through which values and norms are imparted to children (Pike and Zureik 1). Education and political socialization, therefore, present as the acceptable and most widely used measures for socialization. It is important to note that these measures only improve the outcome of how youth grow. Through learning about stratification methods and incorporating the ideologies deemed universal in civic education, is the primary approach towards socialization in western cultures (Pike and Zureik 1). Political socialization is a method through which people are socialized in Canada. Through civic education, the value of having and practicing certain moral values and coin conceptualizations is instilled in the lives of young people. However, it is important to note that there are different approaches towards civic education. The intent for Canada, however, is to stir political participation in the people (Claes, Hooghe and Stolle 613). Still, through civic education, small children can grow up having value for social service. Social service inspires more participation in community and therefore inspires more responsibility and character in peoples. It is, however, important to note that in its diversity, social stratification and socialization is one of the priorities of political socialization. The country is ultimately focused on protecting the ethnicities and the values that they hold. They country, therefore, is better positioned regarding liberal and culturally motivated socia lization(Claes, Hooghe and Stolle 613). Work Cited Claes, Ellen, Marc Hooghe, and Dietlind Stolle.

2.Critically examine and compare urban planning cultures in developed Essay

2.Critically examine and compare urban planning cultures in developed and developing countries and discuss how such cultures have evolved or been adapted to the - Essay Example h planners may continue to wish for a world like it existed earlier where they did not have such numerous factors to take into account before even beginning to plan any town, but such a probability has been closed on the human civilization forever. What remains now to be done is to ensure that whatever planning is now being done in urban areas all over the world, they are established on sustainable grounds. The only way to find out which patterns of planning towns will prove to be sustainable however, is to study the already evolved planning techniques by the developed world and compare between them what should be the best mode for developing towns when it comes to countries which are presently undergoing urbanization. The issue being addressed in this paper is to critically examine and compare urban planning cultures in developed and developing countries and discuss how such cultures have evolved or been adapted to the different development planning challenges being faced in those c ountries. Britain- the first of the European Union countries to become industrialised, had only around 3% of its labour force concerned with the agricultural activities, while almost 80% of its population had become urban by the year it had joined EU that is the year of 1973. Therefore for countries like Britain and even the United Sates or Japan for that matter almost any kind of town planning is mostly urban town planning. The change in patterns of planning however has occurred with time in countries like Great Britain. For instance, the difference between the local town and country planning introduced by the historic Town and Country Planning Act of 1947 and the system which replaced to under the Town and Country Planning Act of 1968 is that of details (Taylor 1998). It was argued in the 1960s that planning should not be focussed on minute details in fact it should be based on generalised and diagrammatic picture of the spatial distributions at any point of time, only filling in

Effects of Media Essay Example | Topics and Well Written Essays - 1000 words

Effects of Media - Essay Example Thus, media is, for better or for worse, charged with nearly sole responsibility for forming people’s ideas of themselves, their relationships with others, and their views of society at large. The other side of the debate claims that mass media has no such effect, at least not in any way that can be conclusively proven. Scientists on each side of the debate claim that the opposing side has flaws in one aspect or another of their research. Such flaws include errors in methodology, misinterpretation of data, clear biases in research, and lack of comprehensive understanding of the media being studied (Gauntlett, 1998). The argument that contends mass media produces profoundly negative effects on those who absorb it is an aggressive one. This often comes across as foolhardy given the lack of empirical data to support the argument itself. Some individuals choose to malign media, television in particular, as being at worst an intentional design to instigate violence in viewers or at best a reckless lack of care regarding the incompetent nature of most viewers. The â€Å"at best† aspect of the argument particularly targets children. At this point, the argument against mass media implies the belief that children are incapable of intelligently and objectively viewing various forms of media, and are given to acting something out that they have seen. This is, of course, a veritable â€Å"Monkey see; Monkey do† interpretation of children’s abilities. In Gauntlett’s words, with regards to psychology and psychology studies, â€Å"children are often considered not so much in terms of what they can do, as what they (apparently) cannot† (1998). Such views are not necessarily appropriate, much less accurate. Chief amongst the complaints of researchers who have yet to accept any effects of mass media is, as was published in the Guardian, â€Å"as far as I can see there has been no
