Salmonella Research Paper
Salmonella is a bacillus bacteria from the Enterobacteriaceae family which can be devided into two species which is Salmonella bongori and Salmonella enterica, and another six subspecies can be divided from the species of Salmonella enterica, which are enterica, salamae, arizonae, diarizonae, houtenae and indica. Salmonellae are found globally in all types on animals, and also in the environment. From an article researched, proposed by C. Wray and A. Wray, it is stated that one of the main habitat of Salmonella is in the digestive tracts of animals which is responsible for diarrhea and also typhoid-like syndromes. Salmonella was first discovered in the year of 1885, when a medical research scientist T.Smith which isolated bacteria from swine …show more content…
Salmonellae are passed through the lymphatic system of into the bloodstream (typhoid form) of the host, which will then be carried by the bloodstream to al over the body and also to the vital organs for formation of secondary foci (septic form). The endotoxins exhibited by the bacteria will cause the vascular and nerve fibers to increase in permeability and decreases those in the blood vessels, which will lead to upset of thermal regulation, vomiting and also diarrhea.

Staphylococcus is a genus of the Gram-positive bacteria which appears as grape-like clusters structure when observed under the microscope. Staphylococcus genus can be grouped into not less than 40 species, where nine of them consist of 2 subspecies and one gas three subspecies. Staphylococcus was first found in the year if 1880 by surgeon A.Ogston during a surgical abscess in a knee joint. Until this day, average estimation of 20% of the human population are carriers of Staphylococcus aureus. Staphylococcus aureus, one of the members of the Firmicutes, is commonly found in the respiratory tract or on the skin, causing skin irritation and infection and also sinusitis and respiratory infection (Ogston A 1984).

The bacteria can be divided into 11 clusters with the taxonomy of the bacteria is based on the 16s rRNA sequences (Takahashi.T

    The genus Staphylococcus includes more than 20 species as described in Bergey 's Manual (2001). Only two are significant to humans, Staphylococcus aureus and Staphylococcus epidermidis. S. aureus colonizes mainly the nasal passages, but it may be found regularly in the oral cavity, gastrointestinal tract and the skin. Staphylococcus epidermidis is an inhabitant of the skin. Of these two Staphylococcus aureus is serious pathogen. Staphylococcus epidermidis is of the normal flora and is not considered to be a serious pathogen (textbookofbacteriology.net). Staphylococcus epidemidis becomes pathogenic when the skin is broken or through contamination from medical procedure. Staphylococcus aureus are only able to invade via broken skin or mucous membranes.…

    Typhi and S. Paratyphi A. Onset of symptoms for this form of Salmonella usually becomes present within six to seventy-two hours after exposure to the bacteria. This subset of the illness causes nausea, vomiting, diarrhea, abdominal cramps, headaches and fever; with symptoms generally lasting four to seven days and completely tapering off within a week. Symptoms and the duration of illnesses may vary from individual to individual depending on host factors, the amount of the dose ingested, and the individual bacterium strain characteristics. In otherwise healthy people, symptoms usually vanish by themselves, but long-term arthritis may develop three to four weeks after the onset of acute symptoms due to an individual’s weak or delayed autoimmune response. Typhoid fever is a more severe, intense, and debilitating form of Salmonellosis. For those under the most serious conditions, up to 10% of people who don’t get treatment may die. Typhoid fever is caused only by the S. Typhi and S. Paratyphi A serotypes of Salmonella, both of which are found only in humans. Onset of symptoms generally occur one to three weeks after exposure to the bacteria, but sometimes may take as long as two months to surface. Symptoms of typhoid fever are much more serious and urgent; high fevers from 103° to 104°F, headaches, lethargy, loss of appetite, a rash of flat rosecolored spots, and…

    Also it can be contracted if there is contamination of sewage water into drinking water. This results in more likeliness of an outbreak in areas of the world where hand washing is less frequently practiced and contaminated water is more prevalent. Most species of primates can also be carriers which makes this a zoonotic disease. Once Salmonella Typhi bacteria is ingested it multiplies and spreads into the bloodstream resulting in Typhoid Fever. The body response with fevers as high as 104 degrees fahrenheit accompanied by weakness, stomach pains, and loss of appetite. In some cases, the infected person may have a rash with flat, rose colored spots. The only way to confirm if a person has been infected is to test samples of their stool and blood for the presents of Salmonella Typhi. With a stool sample the standard test is culture isolation, but this alone will only result in a positive reading 50% of the time. Blood, intestinal secretions (vomitus or duodenal aspirate), and stool culture results are positive for S typhi in approximately 85%-90% of patients with typhoid fever who present within the first week of onset…

    The infectious agent (pathogen) that causes salmonella is called salmonella enteriditis. The bacteria is larger than a virus; but, is visible to the eye with the microscope. It is rod-shaped, gram negative, non-motile bacteria that does not form spores. Interestingly enough it communicates to its fellow bacteria via AHL. It infects the cell, multiplies within it; then, bursts the cell. Special effector protein factors are required for salmonella intestinal invasion and the induction of fluid secretion and for inflammatory responses. There are about six names species names of it, salmonella enteritidis, and salmonella enteric which cause the human disease.…

    Salmonella is one of the most commonly reported types of food-borne illness. Salmonella is caused by a variety of different bacteria. The ensuing illness is treatable, but in some cases, fatal. Most of the time people aren’t even aware they have salmonella, they think something they ate didn’t agree with them and the symptoms are mild and disappear quickly. I believe no one really takes any action of going to a hospital or to their doctor until the symptoms worsen and become unbearable or scary for them that’s at least what I do, which I shouldn’t because instead of me finding out what problem was solving it quickly, I go through the pain and agony until I can’t take t\it anymore. Quite often, the mishandling of food products causes salmonella. In many cases, the bacterium is spread by animal feces coming into contact with fresh foods in the case of eggs, the bacteria come from within the chicken and are already in the egg before it is laid. Eggs are the most common source of salmonella. Infections can also come from contaminated dairy products, meats, and various shellfish. Undercooked meats and poultry may contain the bacteria and on rare occasion fresh fruits and vegetables can also be contaminated. Clinical symptoms are diarrhea, fever, chills, cramping in the stomach and intestine, fatigue and in some cases, headache symptoms can appear as soon as eight hours after ingestion contaminated food products. In some cases, it takes a few days for the symptoms to appear. The illness usually lasts 4 to 7 days, most people recover without treatment. The way you treat salmonella also known as (food poising) is by managing any complications until it passes. Dehydration is most common because of diarrhea so drinking a cup of water or a rehydration drink for each large, loose stool you have. Do not drink fruit juices or soda due to the fact they have too much sugar and they are not good for dehydration. Ways to prevent salmonella are: do not eat row or uncooked eggs, avoid…

    Typhoid fever is most often caused by the Salmonella typhi bacteria. Infection of Salmonella typhi leads to the development of typhoid fever. This disease is characterized by the sudden onset of a sustained and systemic fever, severe headache, nausea, and loss of appetite. Other symptoms include constipation or diarrhea, enlargement of the spleen, possible development of meningitis, and/or general depression. Untreated typhoid fever cases result in mortality rates ranging from 12-30% while treated cases allow for 99% survival. S. typhi has a combination of characteristics that make it an effective pathogen. This species contains an endotoxin typical of Gram negative organisms, as well as the Vi antigen which is thought to increase virulence. It also produces and excretes a protein known as “invasin” that allows non-phagocytic cells to take up the bacterium, where it is…

    Staphylococcus Aureus is a group of bacteria that live on the surface of people's skin and inside the nose. It is normally harmless: most people who are carrying it are totally unaware that they have it. In fact, it is thought that up to 30% of the general UK population carries these bacteria in their nose or on their skin (Nordqvist, 2012). Problems occur if MRSA bacteria are able to enter the body through a cut or wound. Although most people are able to fight off MRSA, there are still some that can’t. People with weakened immune systems or who have undergone surgery can develop more serious problems. In more vulnerable people, Staphylococcus aureus bacteria have been known to cause boils, abscesses, impetigo, septic wounds, heart-valve problems and toxic shock syndrome. In extreme cases, it can result in death (Nordqvist, 2012). How do you know if you have MRSA? MRSA is easy to recognize. Some signs of MRSA are; On the skin, MRSA infection may begin as a reddish rash with lesion(s) that looks like a pimple or small boil. Often it progresses to an open, inflamed area of skin that may weep pus or drain other similar fluid. In some instances, it may appear as an abscess, a swollen, tender area, often with reddish skin covering. When the abscess is cut open or spontaneously bursts open, pus drains from the area (Stöppler, 2012). MRSA is very easily transmittable. Even though MRSA is easy to get. It is also easy to prevent, here are some ways to do so; * Cover your wounds * Clean your hands * Do Not share personal items * Maintain clean environment. *…

    Symptoms vary from mild to severe due to several conditions such as the initiation of the appropriate therapy, age, the choice of antimicrobial therapy, previous exposure to the fever, and vaccination history. These symptoms usually begin to appear from one to three weeks after exposure. Symptoms include malaise, cough, small fever, headache, diarrhea, and red-colored spots on the chest, and magnified spleen and liver. (7) First of all, the main cause of Typhoid fever is the bacteria Salmonella typhi, which infects humans only. It is transmitted by the consumption of polluted food and water. In other words, transmission usually occurs through eating raw fruit and vegetables which are fertilized by human excreta. Additionally, it is easily transmitted through milk and other dairy products such as yogurt and cheese. In a like manner, transmission also occurs when a large number of people drink from the same source of water such as rivers, streams, and lakes. Moreover, flies may transmit the infection by carrying the bacteria, Salmonella typhi, from one person to another…
