Etiology/Causative Agents
Salmonellosis is an illness caused by the zoonotic bacteria, Salmonella typhimurium or Salmonella enteritidis. Salmonella is of the Enterobacteriaceae gram-negative family (CDC). Salmonellosis is commonly thought of as an intense stomach bug, or food poisoning. This illness is most commonly foodborne, and occurs upon the digestion of animal feces that has contaminated the source (Minnesota Department of Health). When food is not properly cooked to remove all bacteria, or if food is contaminated after preparation, this is when the person is most likely to become infected. Due to the portal of entry being through ingestion of the bacteria, it takes form primarily in the stomach. It has a special outer membrane made up of lipopolysaccharides that allows it to coexist with the acidic digestive environment (Microbewiki). It is also possible to be infected by an animal host. Coming in contact with a contaminated

Certain foods are more likely to be infected than others. It is more typical for infected foods to be from animals, or around animals that could contaminate it. Raw meats, poultry, seafood, eggs and fruits and vegetables are the most commonly infected. Bacteria can be avoided if proper cooking precautions are taken. Things like rinsing foods, and cooking them thoroughly can help to prevent food poisoning. Pets can also carry the bacteria. It can be in their fecal matter, or shells of pet turtles. One of the main reasons anyone working in the food industry is required to be out of work if they are experiencing diarrhea is to reduce the chance of transmitting Salmonella. Any feces transferred to food, and consumed will cause food poisoning. This is also why it is so important for everyone to stay on top of personal hygiene and regular hand washing (Minnesota Department of Health). After consumption, the incubation period typically begins to show symptoms within the first three
So as you can see Salmonella typhimurium is a serious microorganism that can create a lot of havoc if it gets inside of a person’s system and although there are many ways to diagnosis it, it must be diagnosed quickly or a person could end up in the hospital.
Typhoid fever is a systemic infection caused by the gram-negative organism Salmonella typhi. It is transmitted through fecal-oral or urine-oral route by either direct or indirect contact of the carrier’s or infected individual’s feces or urine. Humans are the only source of this organism. Ingestion of
Hypothesis about signs and symptoms: Symptoms: cramping, diarrhea, and dehydration. These symptoms were thought to be due to the disease withdrawing fluid from the blood and irritating the stomach and
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
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...
During the investigation, seven test were used to determine the unknown bacterium as Salmonella typhimurium. “Salmonella typhimurium is a genus of gram-negative, non-lactose fermenting, medium-sized, rod-shaped, bacteria, members of the family Enterobacteriaceae, most species having flagella and pili” (medical-dictionary). This bacterium is known for causing food poisoning. This illnesses usually last 4-7 days. Treatments for the illnesses caused by this bacterium are dependent upon the severity of the symptoms, the age of the patient, and the comorbidities.
Abstract: Salmonella is a bacterium that causes one of the most common intestinal infections in the United States - Salmonellosis. The chance of contracting this disease is significantly high, and more and more people are suffering from the symptoms and complications of Salmonella. This paper will discuss about the disease itself, the current outbreaks that are related to this disease, preventions and the treatments.
Salmonella is one of the most common causes of food poisoning. It is a gram-negative, aerobic (oxygen requiring), rod-shaped bacterium that can infect humans, birds, reptiles, and other animals. It results in the swelling of the lining of the stomach and intestines. Salmonella food poisoning occurs worldwide, however it is most frequently reported in North America and Europe. In the United States, Salmonella is responsible for about 15% of all cases of food poisoning (Salmonella food poisoning).
Symptoms, which include diarrhea and abdominal pain, usually begin two to eight days after a person has been exposed to the bacteria and resolve within a week.
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. ...
• Wash your hands thoroughly before and after preparing food and after using the bathroom. Make sure people who live with you wash their hands often too. If soap and water are not available, use hand sanitizer.
The time between becoming infected and becoming sick is about 1 week. Cyclospora infects the small intestine and usually causes diarrhea, with frequent bowel movements. Other usual symptoms include loss of appetite, stomach cramps, bloating, gas, nausea, weight loss and fatigue. Vomiting, fever, headache, body aches, and indications like the flu may be noted. Some infected had no symptoms at all

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...
Cholera is a disease caused by the cholera bacterium Vibrio cholerae infecting the intestines. Usually, the illness is mild, and for some, symptoms of cholera never even present, but sometimes, the disease can also be severe. A severe case of cholera is “characterized by profuse watery diarrhea, vomiting, and leg cramps. In these persons, rapid loss of body fluids leads to dehydration and shock. Without treatment, death can occur within hours” (Cholera Symptoms, Causes, and Treatment). Normally, in a gentler case of cholera, the infected person only has mild diarrhea. “In 5-10% of cases, however, patients develop very severe watery diarrhea and vomiting from 6 hours to 5 days after exposure to the bacterium. In these cases, the loss of large amounts of fluids can rapidly lead to severe dehydration. In the absence of adequate treatment, death can occur within hours” (Cholera Symptoms, Ca...
