The Intestinal Tract Of Human And Animals

The signs or symptoms of E. coli O157:H7. The symptoms begin like three or four days after you are exposed to the bacteria but some people can also feel the effects in like a day to a week. The first symptoms are Diarrhea, which could

The development of antibiotics was an important advancement in 20th century medicine. Previously deadly infectious diseases are now routinely treated with antibiotics. Moreover, for modern-day medical procedures such as chemotherapy treatment to be successful, antibiotic use is necessary. For these reasons, the prospect of bacteria developing widespread resistance to antibiotics is a major concern as it would render many modern-day medical therapies unviable.

Modern-day advances have allowed scientists to develop methods to control pathogens. The more common methods include the use of antiseptics, antibiotics, and vaccines. By definition, antiseptics are chemicals used to kill pathogens. A few widespread antiseptics include soap, vinegar, and rubbing alcohol. Antiseptics are primarily used for the external destruction of pathogens, while antibiotics and vaccines target internal pathogens. Nevertheless, there are and can be difficulties concerning the use of antibiotics. “As antibiotic use has become more common, antibiotic-resistant bacteria have evolved.” This resistance due to evolution is called antibiotic resistance. It results in the antibiotics having no effect whatsoever on the bacteria, rendering the antibiotics useless. When antibiotic resistance occurs, scientists must resume their search to create a new medicine to can kill the mutant bacteria.

Antimicrobial resistant has been called one of the world's most pressing public health problems. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant ones may be left to grow stronger and multiply. Although antibiotics can help treat bacterial infections, a possible side effect is that they can strengthen certain bacterial strains. Antibiotics are supposed to be used for bacterial infections, but are wrongly being used for both viral and bacterial infections. When we use antibiotics on viral infections, deadly bacteria multiplies and becomes stronger. We can fix this problem by using antibiotics for bacterial infections only.

E. coli or Escherichia coli are a kind of bacteria that affects the intestinal or the digestive system of a human being, which can even lead to death. It is one of the subgroup of fecal coliform bacteria. E. coli O157:H7 is that toxic microorganism or bacteria which causes the intestinal disease in the human beings which is most likely to last about a week. The common symptoms of these diseases are that the patient will have diarrhea with blood (Clermont, Bonacorsi and Bingen 2000). However, the serve cases of this disease may lead to kidney problems, which can lead to death especially when the patient is a child or an elderly person. That is, it can act severely in those patients who have does not have a strong immune system. Some types of E. coli are normally found in the intestines of people and animals

coli bacteria is a type of bacteria that can live in the intestines of animals and humans. However, there are some types of the E. coli bacteria, particularly E. coli 0157:H7, that can cause intestinal infections. Symptoms of this type of infection include dehydration, abdominal cramps, fever and bloody diarrhoea. These symptoms can endure 2-8 days after exposure to the bacteria. Since these symptoms generally resolve after a few days to a week, most cases of E. coli 0157:H7 infection can be treated at home.

Furthermore, dangerous strains of E. coli, such as E. coli O157:H7, produces toxins such as Shiga toxins. These toxins have the capabilities to damage the lining of the small intestine, which can result in stomach cramps, diarrhea, vomiting, nausea and bloody stool. If a person can come into contact with a contaminated source, symptoms can appear about three to four days after exposure and can usually last between one to nine days. The infected host is considered contagious until their symptoms stop and even a couple days after that. The way E. coli O157:H7 is diagnosed is by a special stool culture that is sent to a stool laboratory, where tests are run to

Escherichia coli (E.coli) has been a public health issue since the 1980s and is a major concern in food contamination in products like beef, dairy, and fresh produce. E.coli 0157:H7 itself is not invasive but it produces a Shiga toxin which attacks the host small blood vessels in the kidney. This makes the kidneys work harder which can destroy red blood cells and lead to hemolytic anemia (lowered number of red blood cells produced). The incubation period for E. coli ranges from three to eight days. The infection often causes severe bloody diarrhea and abdominal cramps, but can also cause non-bloody diarrhea or no symptoms. E.coli may greatly affects children and the elderly.

A current predicament in the field of science is antibiotic resistance against superbugs.Though fighting against superbugs; which can be defined as a strain of bacteria unable to be killed using multiple antibiotics, is now a large problem, in the past it was not. The evolution of resistance in bacteria due to antibiotic abuse and lack of product development has brought upon us once again the fear of a pre-antibiotic era; one where simple, once easily defeated infections could kill. Already, infectious diseases are the 3rd leading cause of death in the US and the 2nd across the entire world, and drug resistant superbugs send 2 million Americans to hospitals every year; killing 23,000 of those people. And any bacterium can quickly and easily become multidrug resistant, the leading cause of this being antibiotic misuse in both humans and animals.( "Clinical Infectious Diseases." The Epidemic of Antibiotic-Resistant Infections: A Call to Action for the Medical Community from the Infectious Diseases Society of America. UCLA Medical School. Web. 27 Mar. 2016.)

Most people become sick within two to eight days after swallowing the organism. Symptoms of E.coli O157:H7 include fever, nausea, vomiting, stomach cramps, diarrhea that is often is bloody, malaise, poor food intake, and mild dehydration. Some people require no treatment since many infections are self-limited. ( BIO 205 Notes)However, the main treatment is hydration, in the form of either oral or intravenous hydration. Several studies suggest that antibiotics should not be used because they lead to a more severe disease. This increase in severity is believed to be related to the damaging effect of the antibiotic on the bacteria, causing the damaged bacteria release more toxins. The use of antibiotics has been reported to increase the incidence of HUS. Most illnesses resolve on their own within seven days. However, some illnesses last longer and can be more

There was a time I use to consider the colon as a passage for waste products. However, after reading a couple of health related articles, I found that the colon plays many roles in the body, and not just as a passage for waste products. Unfortunately, it is one of the less recognized organs in the body.

Escherichia coli, (E. coli) 0157 is a gram negative bacillus rod shaped bacterium it belongs to the Enterobacteriacea family. (Gould, 2011) E. coli 0157 is a member of a large group of bacterial germs that inhibit the intestinal tract of humans and other warm – blooded animals. (Marler, 2011). This bacterium can live in an environment with or without the presence of oxygen. E. coli has been around since the 1800’s. There is one good benefit to E. coli. Studies have found that E.- coli, colonizes the human bowel within a few weeks of birth and is beneficial to the human body because it reduces the risk of over growth by other bacteria that is more than likely to cause gastrointestinal infection. It was first detected in the stools of babies in 1885. (Gould, 2011) It is named after Esherich, the scientist who 1st isolated it. E. coli is the organism most known for causing urinary tract infections and is especially known for being a main contributor of diarrhea for individuals traveling overseas.

In December 2015, victims began reporting E.coli -related symptoms, including severe stomach cramps, bloody, and vomiting. Although most sufferers recover after a week or so, those who do not seek medical attention run the risk of experiencing

Escherichia coli are bacteria commonly found in the intestines of humans and other animals (Water: Basic Information about Regulated Drinking Water Contaminants 2009). Many strains of E.coli are harmless and contribute to healthy intestinal tracts. However, some strains can cause illness, including abdominal cramps, diarrhea, vomiting, hemorrhagic colitis, and hemolytic uremic syndrome (Tian Ding 2012).

Take for example MRSA (Methicillin-resistant Staphylococcus aureus), a S. aureus strain that was discovered in 1961 to be resistant to the antibiotic methicillin. Webmd indicates that MRSA has now grown its resistance from methicillin to “amoxicillin, penicillin, oxacillin and many other common antibiotics” (MRSA). This increase in resistance of a methicillin-resistant strain of S. aureus can be attributed to the increasing use and overuse of antibiotics, not only in the doctor’s office but also in agriculture. MRSA is only one of many antibiotic resistant strains of bacteria. New resistant strains are evolving rapidly. According to Dr. Ed Warren, “there are high levels of antibiotic resistance in bacteria causing common infections (e.g. urinary tract infections, pneumonia, bloodstream infections) in all regions of the world” (21).
