E.coli is a member of the Enterobacteriaceae family which is also where Salmonella typhinurium is also classified. E.coli lives in the intestines of humans and can cause many infections ranging in severity. It doesn 't even require any growth factors, and can synthesize all essential purines, pyrimidines, amino acids and vitamins, starting with their carbon source, as part of their own intermediary metabolism (Todar). I was nervous about working with E.coli and bacteria because in general before starting this lab because of some of the symptoms they can cause. Especially intestinal swelling (MedLineplus). Even with that stated I have grown to enjoy this experiment and have learned so much valuable information that will benefit me in my nursing…
Which bacterial infection is caused by an unusual strain of E. coli, the common bacterium in the large intestine?…
Escherichia coli are gram- negative bacteria that are normally found within the gut of warm bloodied organisms. There are several strains of E. coli that exist as part of the normal flora of the human digestive system. They prevent harmful bacteria from establishing themselves in the intestines, and they also aide in the production of vitamin K2. Most E. coli strains are not harmful to humans, except for serotype O157:H7, which causes food poisiong and can be life threatening. There are other less common serotypes of E. coli. We will be discussing Escherichia coli O26, which has been linked to an outbreak involving raw clover sprouts.…
coli is a gram negative, bacterium found in the lower intestine of warm blooded organisms. Although E.coli strains are harmless there are serotypes that can cause food poisoning in humans. [2] Harmless strains can be found in the flora of the gut and produce vitamin k¬¬2 and prevent pathogenic bacteria from establishing and are therefore beneficial to the host. The major cause for disease is fecal to oral transmission. It is an ideal candidate for bacterial transformation because it is made of only one cell, reproduces every 20 minutes, is not harmful to people, and cannot survive outside the…
PBHL 3100 Group #4 Foodborne Illness Salmonellosis Foodborne illness, more commonly called food poisoning, is the cause of nearly 48 million illnesses, and an estimated 3,000 deaths in the United States annually. Food poisoning is caused by a bacterial, viral, or parasitic contamination of food. It can happen at any point during the food production realm; growing, harvesting, processing, storing, shipping, or preparing. There are several bacterial, viral, or parasitic agents that can cause food poisoning. The Centers for Disease Control and Prevention (CDC) estimates that 90% of these illnesses are due to the seven most common pathogens: Salmonella, Norovirus, Campylobacter, Toxoplasma, E. coli O157:H7, Listeria and Clostridium perfringens.…
Most types of Escherichia coli are harmless and are actually a part of a healthy human intestinal tract but some are pathogenic. It can be transmitted multiple ways; fecal-oral route, fecal contamination of water, food or fomites, poor sanitation and hygiene (General Microbiology Fact Sheet). A person can show signs and symptoms of Escherichia coli which include fever, bloody diarrhea, may result in hypotension with severe toxemia. The incubation period is 12-72 hours. Knowing the steps and process of finding an unknown is helpful when it comes to the different types of bacteria’s and which are harmful to the body and how to treat…
Food all bacteria need food to grow. Vegetables and raw meat from any animal are significant sources of contamination. Bacteria are always present in animal intestines. These can spread through meat products during slaughter or when a product is minced. . The bacteria can then get carried through the food chain. If the meat product is not cooked properly then the bacteria enter the body through the mouth and are absorbed through the digestive system once we have eaten them.…
A subset of this group of bacteria is known collectively as fecal coliforms, which includes the well-known E. coli, some strains of which are necessary for human health, and some which are pathogenic and can make you very sick. Although the beneficial strains of this bacteria aid human digestion, finding these bacteria in waterways serves as a warning for the potential spread of disease because they can indicate human or animal feces. Therefore, coliform bacteria are used in water quality testing as indicators of other pathogenic bacteria that commonly are found associated with coliforms, e.g., Salmonella, Shigella, Yersinia, Klebsiella and certain strains of E. coli.…
E. coli can come from getting rid of waste through dumping, broken septic tanks, household pet waste, livestock, and storm water runoff.…
The Good Health Hospital records of 2013 have indicated that was an E-Coli O157:H7infection spread among the patients in the Tampa Bay area.” The E coli can be ingested from contaminated foods and cause bloody diarrhea and create a form of kidney failure ( Friis, Sellers,2014)”. There was two males and two woman that were infected .The males were ages 15, and 23; the females were ages 21 and 42. The ethnicity of the females was African American and Caucasian; the males were both Mexican. The outbreak occurred on very hot summer day.…
Fecal coliform is bacteria found in human and animal waste. It can enter our rivers and streams from direct discharge from animals, storm runoff, and human sewage. Some of the sources for human sewage include septic systems from waterfront property, boats that have improper plumbing, and municipal sewer systems that overflow. Water that contains fecal coliform can be harmful to the environment by reducing dissolved oxygen levels. This may reduce the oxygen level enough to kill fish and other aquatic life. In high concentrations, fecal coliform can also cause illness in people that consume the aquatic life.…
Bacteria can get into your body in many ways; the first one is Droplet infection so when you cough, sneeze or talk you expel tiny droplets full of pathogens from your breathing system and then other people breathe that in. The second is Direct Contact which means that some diseases are spread by direct contact of the skin. The third is through contaminated food and drink so when you eat raw or undercooked food or you drink water containing sewage can spread disease for example diarrhoea and food poisoning (salmonella). The fourth is being infected by bacteria through any animal or insect bite for example malaria is spread by a mosquito that contains the malaria virus biting you.…
There are transmitted from unwashed hands to then touching food by being infected by someone that did not wash their hands after going to the bathroom.…
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…
It is caused by the consumption of contaminated food or water causing an acute infection in the gut, however if left untreated can lead to rapid dehydration. (World Health Organization, 2014) This was very common back in the 19th Century due to lack of clean drinking water and poor sanitation, as well as this people from that time were unaware of the dangers of not properly washing your food or washing your hand before you handle food. Due to the lack of knowledge and information this epidemic was allowed to kill many people. During the years since then we have developed a great understanding about how important it is to have clean running water to be able to wash our food before it is prepared and wash our hands.…
