Enterococcus faecalis species is known to be the most common of Enterococci. Enterococcus faecalis is a gram positive bacteria. It is Non-Acid Fast. There are no endospores, but capsules are present. Enterococcus faecalis or Enterococci live within our GI tract, they also can be found in the mouth and vagina. They normally live inside our intestines without problems, the problem occurs when Enterococcus faecalis leaves our intestines, it can create an infection in the blood, urine, or in wounds. E. faecalis can cause a problem in people with a lowered immune system because they are more infection prone for example cancer patients, people on dialysis, people who have HIV or AIDS, transplant patients, etc. Interesting note about E. faecalis is
The Gram positive bacteria has been nicknamed Posi. The Gram positive species’ morphology includes having an opaque opacity with a smooth margin. The moisture content of the Gram positive species is shiny and the pigmentation is gold. The Gram positive species grows at an optimal temperature of 37°C. The shape of the Gram positive species is a cocci, with an arrangement of grapelike clusters. The Gram positive species’ size ranges from .5-1.5 µm. Oxygen requirement of the Gram positive species is facultative, and has complete lysis of red blood cells. All results are summarized in Table
The results of the gram stain test were cocci and purple. This indicated that the unknown bacteria were gram positive. The gram stain test eliminated Escherichia coli, Klebsiella pneumonia, Salmonella enterica, and Yersinia enterocolitica as choices because these bacteria are gram negative. Next a Blood Agar plate was used because in order to do a MSA or a Catalase test there needs to be a colony of the bacteria. The result of the Blood Agar plate was nonhemolytic.
The purpose of this laboratory is to learn about cultural, morphological, and biochemical characteristics that are used in identifying bacterial isolates. Besides identifying the unknown culture, students also gain an understanding of the process of identification and the techniques and theory behind the process. Experiments such as gram stain, negative stain, endospore and other important tests in identifying unknown bacteria are performed. Various chemical tests were done and the results were carefully determined to identify the unknown bacteria. First session of lab started of by the selection of an unknown bacterium then inoculations of 2 tryptic soy gar (TSA) slants, 1 nutrient broth (TSB), 1 nutrient gelatin deep, 1 motility
The SMART goal for the patient’s diagnosis of diarrhea is that the patient will defecate formed, soft stool every 1 to 3 days and will express relief of cramping with little or no diarrhea. The intervention to meet this smart goal is the administration of fidaxomicin, a narrow spectrum antibiotic, to treat the infection of Clostridium difficile (Sears, 2013). Another nursing intervention for the treatment of diarrhea is assessing the patient for sodium and potassium loss, as well as explaining the prevention methods to avoid the spread of excessive diarrhea (Mitchell, 2014). The nurse must also provide proper skin integrity care to the peritoneal are and make the environment safe and easy for access to the bathroom. The SMART goal for the patient’s diagnosis of acute pain is that the patient will state relief of pain in abdominal area after treatment with opioids in a 24hr period. The nursing intervention for acute pain is the administration of opioids as well as positioning to keep patient in as much comfort as possible and take pressure off of the abdominal area. The nurse must also assess the patient’s vital signs and pain level
Salmonellosis is a bacterial disease that affects the intestinal tract. It is one of the most common foodborne disease worldwide. It is caused by a Gram-negative, lactose non fermenter, glucose fermenter,
Many children around the world , especially in third world countries suffer many bacterial infection of the gastrointestinal system as a result of lack of awareness and the spread of the disease in the less attention to hygiene and the environment . In order to explain this word gastrointestinal tract infection , especially the stomach and intestines , it can result from infection by bacteria or virus or other parasites (1) . Some of the causes of inflammation as a result of eating food poisoning , especially meat and eggs . However , some symptoms of severe cases are headache , nausea , vomiting , general weakness , diarrhea and pain , the illness begins suddenly with high fever , vomiting , abdominal pain and stool liquid to water that may contain some blood and mucus . The result of drought through loss of fluids and salts and lead an alliance with the poisoning to the collapse of the circulatory system in diseases such as cholera (2) . It must be conducted in diagnosing bacterial to find the source of infection because it causes illness and death of millions in the third world and in particularly children as mentioned . In this report will refer to the most common types of bacteria cause gastrointestinal tract infection for example , Shigella , Salmonella , Vibrio and Campylobacter (3) . First of all , Shigella is gram negative , nonmotile , non lactose fermenting and H2S production . There are four important species , S. sonnei , S. flexneri , S. boydii and S. dysenteriae is the most serious . Next is Salmonella which is gram negative as well , non lactose fermenting and production H2S . These species are S. typhi and S. paratyphi found in humans and animals . Finally , Campylobacter is gram negati...
Eukaryotic microorganisms can be defined as organisms whose cells contain a nucleus and other organelles enclosed in membranes. It is said that all multicellular organisms are eukaryotes which mostly comprises of animals, plants, and fungi. They are known to be much larger than prokaryotes which contain no nucleus because they are multinucleated organisms. Eukaryotes were said to have developed about 1.6 – 2.1 billion years ago. But that is only an approximation. We would not be here if eukaryotic microorganisms did not exist. These organisms tend to share a common origin and could be treated as a super kingdom, empire, or domain. Lastly, many unicellular organisms are also eukaryotes e.g protozoa. The types of eukaryotes are algae, yeast, fungi and protozoan.
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.
Escherichia coli (E. coli) is a member of the Enterobacteriaceae family of organisms. It is a non-spore forming, facultative anaerobic, gram negative rod capable of growing on a variety of media and, similar to other members of the Enterobacteriaceae family, contains the enterobacterial common antigen. Most E. coli are part of the normal flora of the human gastrointestinal tract, however some strains are pathogenic and capable of causing clinical disease. Epidemiologic classification of E. coli is based on the expression of certain surface antigens. The three of greatest importance are the somatic O polysaccharide (part of the lipopolysaccharide or Gram negative endotoxin), the K antigens (part of the capsule), and the H antigens (flagellin proteins). The bacteria regulate the expression of these antigens through antigenic phase variation. This process allows the organism to selectively express or not express the antigens, which aids in protection from antibody-mediated cell death. Enterohemorrhagic E. coli (EHEC) are strains that produce exotoxins (particularly verotoxins) that result in hemorrhage of the intestinal mucosa. There are several serotypes of EHEC; the most clinically significant is O157:H7.
when I first read this microorganism name the first thing that comes to mind was “vampire” blood sucking. Therefore, I chose this bacterium as my unusual microbe due to the unrealistic name. Vampirococcus is a predatory prokaryote that attack and consume their prey, as the name implies they attach themselves to other bacteria and ‘sucks’ their cytoplasm using enzymes. Vampirococcus is a gram-negative that has ovoid shape, they usually found in sulfur lakes northeastern Spain. However, it was found in 1983 by Esteve and was classified as one of few kinds predatory bacteria. The micro-organisms that feed on other micro-organisms are classified as predatory.
The student also forget to apply aseptic technique throughout experiment, which made experiment vulnerable to contamination. Unknown 3 After gram staining, it was revealed that unknown 3 microscopic morphology was Gram positive cocci in chains Enterococcus faecalis. When observed under the microscope, the bacteria’s morphology displayed a purple color, round shape, and in short chains. Enterococcus faecalis is most often found in large intestine of humans2.
Enterococcus faecalis is a genus of gram positive cocci and form short chains or are arranged in pairs. They are nonmotile, facultative anaerobic organisms and can survive in harsh conditions in nature. There are over 15 species of the Enterococcus genus but about 90% of clinical isolates are E. faecalis. E. faecalis is a nosocomial pathogen because it is commonly found in the hospital environment and can cause life-threatening infections in humans. It is a bacterium that normally inhabits the intestinal tract in humans and animals but when found in other body locations it can cause serious infections. The most common sites for E. faecalis infections are the heart, bloodstream, urinary tract, and skin wounds. Due to vancomycin-resistant Enterococci, many antibiotics have been shown ineffective in the treatment. In this paper, I will describe the ecology and pathology of E. faecalis; the antibacterial resistance; treatment; and, what you can do to prevent Enterococcus infection.
Gut microbiota is a community of bacteria that can be found in the intestine and is constantly changing. These bacteria are considered complex because there are about 1 trillion bacteria and about 1000 different types of species of bacteria. There have been studies that helped determine and explain several factors that influence the number of bacteria that reside in the intestine and what effects they have, resulting in alteration of the composition. These factors can influence a person’s metabolism, energy balance, gut permeability, and inflammation.
Gastroenteritis is a general medical condition which affects people every day. For this example, we are heading to Florida for a standard football game between a North Carolina football team and local Florida team. During the football game, several players on the North Carolina team suddenly began to vomit and have diarrhea. Despite their illness, the players continued to play. Due to the nature of the game and football being a contact sport, it made it difficult for players to avoid contact with feces and vomitus. After the game, the Florida players also had similar gastrointestinal symptoms. The only contact between the teams had been on the playing field. The North Carolina team and staff received a locker-room lunch before flying to Florida for the game. The locker-room lunch was provided by a restaurant with the food handlers denying having had any diarrhea recently. Becker, Moe, Southwick, and MacCormack
