Description
Salmonella is an intestinal infection caused by Salmonella enterica bacteria. You can become infected by eating foods contaminated with Salmonella or by touching infected pets. In rarer cases, Salmonella infection can also be carried in medical products that were derived from contaminated animals. Before a Salmonella infection can begin, somewhere between 100,000 and 100,000,000 Salmonella enterica bacteria must actually be swallowed. Salmonella bacteria invade the intestinal wall, where they trigger inflammation. They also produce irritating intestinal poisons. In some rare cases, Salmonella bacteria may enter the bloodstream and settle in tissues and organs far away from the intestines. This spread of Salmonella infection is most common in infants, in the elderly, and in patients whose immune defenses are weakened.
Symptoms
After someone has eaten food contaminated with Salmonella bacteria, it usually takes 8 to 48 hours for symptoms to begin. Symptoms of Salmonella include fever, chills, nausea, vomiting, abdominal pain, and muscle aches.
Prevention
You can prevent Salmonella by thoroughly cooking all meats, ground beef, poultry and eggs, and by promptly refrigerating all leftovers. Whenever silverware has touched raw meat, wash these items thoroughly with soap and water. Also, avoid eating eggs that are raw or partially cooked. Frequent hand washing is particularly important, especially after using the rest room.
Treatment
Doctors do not usually prescribe antibiotics, since patients typically recover on their own in a few days. Since many strains of Salmonella are resistant to one or more antibiotics, a patient may be treated initially with one antibiotic, then switched to a second antibiotic if it doesn’t work.
Prognosis
Most patients with Salmonella recover within 5 to 10 days; however, they may continue to pass Salmonella bacteria in their stool for up to 2 months.
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
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.
E. coli are bacteria that can cause an infection in various parts of your body, including your intestines. E. coli bacteria normally live in the intestines of people and animals. Most types of E. coli do not cause infections, but some produce a poison (toxin) that can cause diarrhea. Depending on the toxin, this can cause mild or severe diarrhea.
Be sure to take medication exactly as directed and do not stop therapy without speaking to health care provider. The nurse should evaluate the effectiveness of any antibiotic treatment to be sure the infection is going away and not getting worse. Improving of the signs and symptoms of infection should be seen by 5 days.
Prognosis: After early diagnosis and full treatment, syphilis can be eradicated from the body. Secondary syphilis may take a few weeks to a year to be completely free the system. One third of the patients who receive no treatment get late syphilis, which may result in death.
In America, there are many people who never think twice to question what they are eating. Most American’s simply assume, if it tastes good it must be good. This is unfortunately not the truth. In 2001, a young boy tragically passed away after ingesting meat that was contaminated with the Escherichia Coli bacteria (Metzger). Escherichia Coli is a bacterium that is normal inside of the intestines of most animals including humans, but when it is presented outside of the intestinal tract it can be fatal. E. Coli is spread when cattle are slaughtered and the E. Coli from the hides of the animals is getting transferred into the meat (Daluiso). This bacteria is clearly very harmful to the human body. After the death of this child, his grandma and mother tried very hard to get a law passed that would better regulate the production of food and decrease contamination (Metzger). Kevin’s law is:
In order to isolate bacteriophage specific for Salmonella, we will following procedures below. Firstly, we will inoculate 5 mL tryptic soy broth with Salmonella. Then we touch a colony of Salmonella by using a sterile needle and transfer it to the tube consisting LB broth. After that, we incubate the culture overnight at 37oC. The next day, we will inoculate another tube with 4.5 mL of water sample that we take from poultry farm nearby that we suspect as source of Salmonella contamination on the squid water farm. We also add 0.5 mL of overnight Salmonella culture and 0.5 mL of 10X tryptic soy broth. The mixture will be incubate for about 24 to 48 hours at 37oC. During this incubation period, we expect phage in water sample will be able to bind to Salmonella. The phage also will replicate and lyse the bacteria. Therefore, the significance of this step is to amplify the phage that can infect the Salmonella.
You can also get salmonella poisoning from meat. People think that the problems come from eating red meat and are opting for fish over steak, but new evidence proves that fish can cause health problems too, risks that can’t be cooked away. This is a growing problem called histamine poisoning (Peck). Children are learning at a younger age that they don’t like meat, maybe because they don’t like the taste, or maybe it’s because they have a fear of eating their favorite cartoon or movie hero. For example, the pig from the movie “babe”.
Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule. The capsule prevents the white blood cells and antibodies from destroying the invading bacterium. Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not cause disease. They release digestive enzymes onto the organic matter. The enzymes breakdown the large food molecules into smaller molecules, which are absorbed by the bacterial cells. Parasites live on or in living organisms, and may cause disease. A few types of bacteria are Autotrophic, they can synthesize the organic nutrients they require from inorganic substances. Autotrophic bacteria are either photosynthetic or Chemosynthetic. The photosynthetic bacteria contain chlorophyll that are different from the plant chlorophyll. In bacterial photosynthesis, hydrogen is obtained by the splitting of compounds other than water.
First-time infection. Symptoms often improve significantly within a day or so of antibiotic treatment. However, you’ll likely need to take antibiotics for three days to a week, depending on the severity of the infections.
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.
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...
Each and every year millions of people become sick because of food poisoning and other food related illnesses. Many of these illnesses can easily be prevented by properly cooking and handling food in the kitchen. Unfortunately, many people around the world are unaware of the consequences that can occur from contaminated and undercooked food. It is important for every individual who is planning on making a meal in their life (virtually everyone) to understand how to properly prepare their meal.
