Bacillus cereus, a commonly occurring pathogen which can survive in remarkably hostile conditions, is typically found in soil. B. cereus has been recognized as an agent of food poisoning since 1955. The natural environmental reservoir for B. cereus consists of decaying organic matter, fresh and marine waters, vegetables and fomites, and the intestinal tract of invertebrates, from which soil and food products may become contaminated, leading to the transient colonization of the human intestine. Illness associated with B. cereus can occur when heat-resistant B. cereus endospores survive cooking. If the food is then inadequately refrigerated or held for extended periods at improper temperatures the endospores can germinate and multiply. Once the spores germinate, the vegetative cells can multiply and produce illness causing enterotoxins. Bacillus cereus is known to cause two distinctly different types of food-borne illness. The first type of illness, referred to as the Rapid-onset (Emetic) Vomiting-type, is characterized by nausea and vomiting. The incubation period ranges from 1 to 6 hours. Both the symptomology and incubation period mirror those of Staphylococcus aureus. The second type of illness, generally referred to as the Slow-onset Diarrheal-type, is characterized by diarrhea and…
He contracted Clostridium difficile and survived the initial infection, but lost most of his intestine. his waste empties into a ileostomy bag now. He came back to the states from China with some intestinal pain, where his doctor prescribed him with CIPRO, a broad range antibiotic. Nevertheless, the drug effectively cleared out all his natural bacteria, letting the Clostridium difficile become unopposed space-decently in his gastoral intestine. His doctors realized how fast the infection was growing, so they put him in a month long coma as they tried and failed to treat it. In the end, they took out his massively swollen intestine and left him with a tiny bit. Corresponding, Mariana Bridi Costa from Brazil was living a dream, traveling the world trading her beauty for a career in modeling, while lifting her family out of poverty. Except during a tour of contests, she contracted Pseudomonas aeruginosa, a multiresistant urinary tract infection. It worsened rapidly, and turned into septic shock. In desperate attempt by surgeons they amputated her hands, legs, and some stomach. She sadly died the next day after she completely stopped breathing. These deadly scenarios are prevalent all over the world now, and a quick saviour is nowhere in…
Doctors have put healthy peoples fecal into a pill that helps a disease called Clostridium difficile, or C-diff. This disease cause abouot 14,000 to die every year. These fecal capsules have cured 27 patients with C-diff, while antibiotics failed to help. By taking this capsule, it can restore good bacterias and prevent reinfection. They are taken through colonscopies. It takes many pills to hold bacteria for treatment. An example of someone using the capsules, had her daughter as a donor, and she has felt better ever since. Huge potential is found in using these capsules, especially for hospitalized patients at risk and using normal…
Clostridium difficile grows without oxygen and in normal temperature of 98.6 that is why the body makes a perfect host. C.difficile exists in two states-the vegetative (growth) state or the spore state. In the vegetative state the bacterium is able to use nutrients to grow and divide. When conditions become unfavorable, C.difficile is able to enter a dormant state and form a highly resistant spore. When conditions become favorable C. difficile is able to return to its vegetative state. Spores can survive up to two years on inanimate objects. C. difficile causes disease by the release of two protein enterotoxins, toxin A and toxin B, which cause severe inflammation and mucosal injury to the colon-colitis.…
It was originally predicted that in minimal media, the bacteria would have greater enhancement of growth with squalane than those in nutrient broth, as the squalane compensates for the otherwise scarce energy and carbon availability. This was not evident in the experiment, as there was no difference in enhancement of growth between media. Despite this, there was still a significant increase in growth in samples supplemented with squalane within media groups. This further supports the general growth-enhancing effects of the substance, but does not conclusively demonstrate its mechanism.…
Clostridium Difficle is a nosocomial infection acquired mostly in hospitals. In 2005 it was consider the most precarious infection to bombard North American in a decade. Armed with knowledge about the infection, transmission, environmental factors, alternative treatments, prevention and ways to control C.diff healthcare workers can better be prepared to help fight the spread of this deadly infection. A…

On November 14, 2012, Rita Bernstein visited Bergen Community College to talk about Escherichia Coli O157:H7. Escherichia coli or better known as E.coli is a tube-shaped bacterium that is found in the stomachs of warm-blooded animals. O157:H7 is a member of the E.coli family, which produces shiga toxin, and are capable of producing bloody diarrhea. E.coli O157:H7 attacks red blood cells, it interrupts flow of oxygen, and it breaks down walls of vessels.…
Clostridium Difficile, C. difficile or more commonly called C. diff. belongs to the “domain bacteria which makes it a prokaryotic, its Phylum is Firmicutes, its class is Clostridia, its order is clostridiales, its family is Peptostreptococcaceae” (Brymer). “Clostridium difficile is a spore-forming, Gram-positive anaerobic bacillus that produces two exotoxins: toxin A and toxin B. It is a common cause of antibiotic-associated diarrhea (AAD). It accounts for 15-25% of all episodes of AAD.” [1] The two toxins produced by C. diff are toxin A and toxin B. “Toxin A is an enterotoxin and cytotoxin that causes fluid secretion and increased musical permeability because of the increased inflammation” (Brymer). “Toxin B is a cytotoxin, that bind to…
diff). Clostridium difficile is a type of bacteria that lives in your intestines. It generally will do no harm to the human body but, certain things can lead to this bacteria to grow, which will end up causing some serious life threatening problems. "Most people who get a C. diff infection are getting medical care. The biggest risk factor is taking antibiotics. While antibiotics may cure the bacteria that are making you sick, the drugs can also knock out the healthy bacteria in your digestive tract. Then C. diff takes over." says webmd.com. As of 2011 C. diff was the cause of half a million infections in the United States.There are other bacterial infections that have a serious threat such as Multidrug-Resistant Acinetobacter and MRSA. Multidrug-Resistant Acinetobacter is a bacteria that are mostly found in either soil or water. It has the possibility of living in human skin for days at a time. The people that are mostly seen with this bacteria is the people who have been in the hospital with another illness for a while. This infection is very dangerous because it is faster at developing more resistance against antibiotics than any other bacteria. On the other hand MRSA is a bacteria that stands for methicillin-resistant Staphylococcus aureus. As stated by mayoclinic.org "infection is caused by a…
One of the most common foodborne illnesses in the United States is Clostridium perfringens (C.perfringens). According to the Center for Disease Control, it is responsible for approximately one million cases of foodborne illness each year (Center for Disease Control, 2011). This bacterium is an anaerobic gram-positive bacterium. This means that it requires little to no oxygen to survive. It is found in many environmental sources including soil, sewage, raw meats, and vegetables as well as in the intestines of humans and animals. The bacterium creates a toxin in the intestines.…

Clostridium difficile (C-difficile) is a common bacterium that is a frequent cause of infection in the colon and effects numerous patients. Clostridium difficile increases the hospital costs associated with inpatient care, including identification of the organism as well as treatment. The most common cause of C-difficile infection is the elimination of normal intestinal flora caused by antibiotic use. Standard treatment of C-difficile infection includes the use of oral (Flagyl) and intravenous (Vancomycin) antibiotic therapy. The use of fecal transplantation to treat C-difficile infection is increasing in popularity. Research regarding fecal transplantation dates back to 1958; however, the efficacy of fecal transplant for the treatment of C-difficile are rapidly emerging with noted benefits for patients. The mere thought of presenting fecal transplantation for the treatment of a C-difficile infection is often dismissed because of limited available evidence and the concerns about using someone else’s stool to treat the infection. The necessity to educate patients with C-difficile is an additional challenge. Potential donors and recipients need to be assured of minimal risks associated with the screening and transplantation process. The ability to educate society on the results of evidence-based practice regarding the treatment of C-difficile with fecal transplantation should minimize concerns and enhance patient outcomes. The creation of a patient education programs is increasingly beneficial when multiple health care professionals and interdisciplinary teams are involved. Thus, a project objective in implementing an educational patient program for fecal transplantation is the creation of an informative brochure for potential use in the Endoscopy Department at Sharp Memorial Hospital by December 2014. The…
Fidaxomicin is an orphan drug that treats Clostridium difficile infections. This drug inhibits bacterial RNA polymerase and cause rapid death of C. difficile bacteria. It undergoes minimal systemic absorption and causes its effects directly in the GI tract. C. difficile is a sporeforming, anaerobic bacillus that transmitted to human via the fecal-oral route. The FDA-approved dosing of fidaxomicin is 200 mg twice daily for 10 days with or whithout food for adults. The most common adverse effects of this drug are gastrointestinal events like vomiting, nausea, gastrointestinal hemorrhage, and abdominal pain.…
a. The bacteria that causes botulism are found in soil, water, animal guts and dung. When the spores exposed to low oxygen and certain temperature, they produce botulinum toxin, able to germinate, metabolize, food sources through an aerobic respiration to produce toxin. The toxin blocks the release of acetylcholine from motor nerve endings causing paralysis symptoms. The botulism either food born, eating contaminated home-canned foods where the fermentation takes place. or through abrasion in the body skin where the Clostridium bacteria can infect the wound releasing the neurotoxin, this has been increased recently because of the use of tar heroin injection. or infant that he ingests spores and the spores grow in the intestine producing neurotoxin…
