Introduction
Salmonella typhoid bacteria have over 100 strains in the world today. Most cause illness in humans, but only a few of those strains cause the illness Typhoid Fever (Pike, 2014). Typhoid is a bacterium that has been very devastating to the human race for centuries. Typhoid thrives in undeveloped countries and countries with high populations and poor sanitation procedures. But, it is still a relevant disease here in the United States because of its ease of spread once someone is infected (Pollack, 2003). Antibiotic treatment is usually successful when treating Typhoid Fever, but it still has the ability to cause death, even with treatment of advanced medicine and antibiotics. When one thinks of salmonella, they will most commonly think of a food borne illness (food poisoning symptoms) caused by eating raw or undercooked animal products such as undercooked chicken or pork. That is the effect of some strains of the bacteria, but not the one that causes typhoid fever (Pike, 2014).
Typhoid Facts and History
Salmonella enterica typhi (typhoid fever causing bacteria) are parasites with no other known living environment outside of humans (Pike, 2014). Typhoid has the ability to cause large outbreaks and the Centers for Disease Control and Prevention (CDC) has classified Salmonella species with other food safety threats as high priority potential bioterrorism agents (Baggier, Burwen, Haber, & Ball, 2004). Salmonella enterica typhi is one of three species of the Salmonella genus. Typhoid gets its name from Typhos, which means smoke, or to cloud, or vapor. It was thought to be transmitted through a “cloud of sickness called miasma” (Pike, 2014). When someone recovers from typhoid fever, about 3-5% become carriers o...

Diagnosis of salmonellosis involves testing a sample of stool, as well as isolation from samples of tissue, blood, or urine. Since it is commonly mistaken for the flu and involves similar symptoms to other illnesses, the method of diagnosis for salmonellosis is pretty hard to come by. Most people with salmonellosis don’t seek treatment, so they’re never aware that they even had it. Since it is a foodborne pathogen, has a common route of infection via oral ingestion, and is found in food products that we consume on a daily
Judith Walzer Leavitt's Typhoid Mary details the life of Mary Mallon, one of the first known carriers of the typhoid disease. Leavitt constructs her book by outlining the various perspectives that went into the decisions made concerning Mary Mallon's life. These perspectives help explain why she was cast aside for most of her life and is still a household catchphrase today. Leavitt paints a picture of the relationship between science and society and particularly shows how Mallon was an unfortunate example of how science can be uneven when it is applied to public policy. This paper will focus on the subjectivity of science and its' interaction with social factors which allowed health officials to “lock[ing] up one person in the face of thousands”, and why that one person was “Typhoid Mary” Mary Mallon (Leavitt p. #).
August 1940, a year from the beginning of World War II and the date of which marks the beginning of Unit 731, a shorten name for Epidemic Prevention and Water Purification Department of the Kwantung army. Unit 731 was part of a Japanese biological and chemical warfare research department with the goal of developing biological and chemical weapons for use by the Japanese Kwantung army. It was given the nickname Asian Auschwitz for its cruel human experimentations that they have conducted toward their prisoners. Unit 731 did not spare anyone from its experiments and had a wide range of subjects, including infants, elderly, pregnant women, and prisoners. Some of the experiments included amputating limbs, vivisection without anesthesia, and injecting diseases into the body. Unit 371 members did cruel experiments, but their actions can be explained through the views of Staub and Doris.
The outburst spread of diseases in a population causes people to panic and become hopeless. The main reason diseases spread is due to unsanitary living styles. Also when a disease first begins, it is really hard to find a cure right away. A very deadly, infectious disease known as Typhus spread during the Holocaust. Typhus is caused by rickettsia and is spread by lice and flees.
Anthrax is one of the most preferred biological warfare agents for many highly identified reasons. First, anthrax is extremely lethal. Anthrax can contain up to 100 million lethal doses in just one gram of anthrax spores, which is 100,000 times more lethal than any other biological warfare agent. It is also known that inhalation anthrax is almost always fatal if the symptoms are allowed to progress without any treatment. Anthrax is also the silent and invisible killer. On top of the fatality rate of anthrax, there are also very low barriers to produce the biological weapon. Anthrax spores are very easy to produce in large quantities, and the process of production is very inexpensive. Also, there is plenty of available information on how to weaponize anthrax and not a whole lot of technology is needed to be able to produce anthrax. Anthrax is also easy to weaponize because it is extremely stable as a dry powder in the form of spores. These spores can live for decades and still be very lethal to the human body. Anthrax can be put into an aerosol form disseminated into a spray can, and it can also be freeze-dried into a bomb. Presently anthrax is the most preferred biological agent is because we have no accurate detection capability.
Many children around the world , especially in third world countries suffer many bacterial infection of the gastrointestinal system as a result of lack of awareness and the spread of the disease in the less attention to hygiene and the environment . In order to explain this word gastrointestinal tract infection , especially the stomach and intestines , it can result from infection by bacteria or virus or other parasites (1) . Some of the causes of inflammation as a result of eating food poisoning , especially meat and eggs . However , some symptoms of severe cases are headache , nausea , vomiting , general weakness , diarrhea and pain , the illness begins suddenly with high fever , vomiting , abdominal pain and stool liquid to water that may contain some blood and mucus . The result of drought through loss of fluids and salts and lead an alliance with the poisoning to the collapse of the circulatory system in diseases such as cholera (2) . It must be conducted in diagnosing bacterial to find the source of infection because it causes illness and death of millions in the third world and in particularly children as mentioned . In this report will refer to the most common types of bacteria cause gastrointestinal tract infection for example , Shigella , Salmonella , Vibrio and Campylobacter (3) . First of all , Shigella is gram negative , nonmotile , non lactose fermenting and H2S production . There are four important species , S. sonnei , S. flexneri , S. boydii and S. dysenteriae is the most serious . Next is Salmonella which is gram negative as well , non lactose fermenting and production H2S . These species are S. typhi and S. paratyphi found in humans and animals . Finally , Campylobacter is gram negati...
Salmonella is one of the most common food-borne diseases that attack an enormous amount of people in poor countries every year. It is shown that “Today, it still attacks some 17 million people in poor countries each year, and kills about 600,000 of them. Back before antibiotics such as chloramphenicol, typhoid was very much feared” (Trek 1). Despite the advance in technology and medicine, Salmonella is

enemy. It has been around for thousands of years, but in different forms. To take a case in point, the article, “History of Bioterrorism,” states that the Assyrians poisoned the well of their enemies with rye ergot in the 6th Century B.C. More recent examples of bioterrorism include the anthrax inhalation from received mail in 2001 (Office of The Surgeon General). Although these are only recorded acts, there is a whole other story to what should happen once a victim is diagnosed with any type of bioterrorism and what treatment they should undergo, if one exists. For example, the medical response and treatment are different for anthrax, smallpox and tularemia. The medical response and treatment depend on the severity of the case and the type of bioterrorism.
Salmonella is one danger that has caused many effects to consumers. Walsh writes about one incident when an outbreak “from tainted peanuts that killed at least eight people and sickened 600,” (Walsh 167). This incident left many people asking the same question, how can we trust the food that we put into our bodies? Salmonella, a type of food poisoning caused by bacteria found on different food types has caused an epidemic because of its domino effect on food and our health. Once one factory is contaminated, that factory could be housing both crops and meat, which is then transferred to our supermarkets and on our dinner tables. ...
Biological warfare. Using infectious diseases, bacteria, viruses, fungi, and biological toxins to kill animal, plants, and even humans as an act of war. But one of the most gruesome biological warfare scientists is Shiro Ishii. From testing germs of warfare on Chinese prisoners of war, to killing hundreds of innocent civilians, Shiro was one of the most harrowing biological warfare scientists in his time.
Food-borne transmission refers to any illness that results due to the consumption of contaminated food, pathogenic bacteria, viruses, or parasites that contaminate food, as well as chemical or natural toxins such as poisonous mushrooms (cdc.gov). Bacteria is the most often the pathogen that causes food-borne illness. This is usually due to improper handling of foods, improper preparation of food and improper food storage. According to the CDC, the top 5 contributing pathogens to food-borne illness are Norovirus, non-typhoidal Salmonella, Clostridium perfringens, Campylobacter spp. and Staphylococcus aureus.
There is a little known piece of paper that was formed by the United Nations called the Biological Weapons Convention. It was formed in April 1972 as part of an effort for disarmament, production and stockpiling. This document was entered in to force on 26 March 1975, and over the years there have been several conferences to review and amend the Convention. As of today, there are one hundred and ten signatory states and one hundred sixty eight state parties. There are four members of the depositary governments: Russian Federation, United Kingdom of Great Britain, Northern Ireland and the United States of America.
Salmonella is also a bacterium that is widespread in the intestines of birds, reptiles, and mammals. It can spread to the human species a variety of different ways; through foods or animal origins. Some examples of food involved in outbreaks are eggs, poultry and other meats, raw milk and chocolate. The illnesses it causes are typically fever, diarrhea, and abdominal cramps. In people with poor underlying health or weakened immune...
Typhoid fever (also known simply as typhoid) is a symptomatic bacterial infection that is characterized by various mild to severe symptoms, including fever, marked headache, and malaise. Other reported symptoms include anorexia, relative bradycardia, splenomegaly, nonproductive cough in the early stages of the illness, visible rose spots in the trunk, and constipation more often than diarrhea in adults (Heymann, 2015). The causative agent of typhoid is Salmonella enterica serovar typhi. Salmonella organisms penetrate the mucosa of both the small and large bowel, coming to lie intracellularly, where they proliferate. Initially S. typhi proliferates in the lower small intestine from where systemic dissemination occurs to the liver,
