Helicobacter Pylori Research Papers

To have a test done to check for the presence of syphilis, you must see a physician who then swabs the ulcer or sore and sends it off to the lab where it is then checked for the infection. A simple blood test can also detect the infection as well if you don’t have any current signs.

Even though H. pylori is a "neutralophile", it can survive in the very acidic environment in the human stomach due to a variety of acidic-adaptive mechanisms, such as the ability to utilize urease to break down urea

This experiment was conducted to find the genus and species of an unknown bacteria prescribed by the lab teacher, which was unknown bacteria GA3 in my case. Identification of unknown bacteria techniques are used on an every day basis to figure out what type of bacteria it is and to find the best method of how to treat a patient with this bacteria (1). All five “I’s” of Microbiology were used in the testing for the unknown culture. Inoculation was used several times to put the unknown culture into agar plates or into biochemical test tubes. After Inoculation of these tubes or plates, they always were placed into the incubator for further growth and development. Isolation was used to make sure we got the correct bacteria we were testing for. After each further isolation, we gram stained the culture and inspected the culture under a microscope to further help in the identification process of the unknown bacteria. Multiple tests were done on the unknown culture to make sure we were confident in what kind of bacteria the unknown was.

The first step toward identifying this unknown organism was to perform a Gram Stain to differentiate between gram positive and gram negative bacteria. This is an important step because it directs what the next tests will be. My Gram Stain on sample #12 showed that the bacteria was gram negative, however, after receiving the results of the OF glucose, H2S, Citrate, Urease and Motility tests, it was apparent that my Gram Stain was contaminated. I then performed a catalase test which came back negative, so I ordered a Bacitracin disc, Optochin disc and a CAMP test which had to be incubated overnight. After receipt of those test results,

Bacteria are ubiquitous; they can be found on the skin, in the soil, and inside the body. Because of the very nature of this ubiquity, it is important to be able to determine between different strains of bacteria. An example of this is determining the causative agent for a disease so that the patient will be treated with the appropriate antibiotics. It may be important to determine the bacteria in a certain region, because like with enteric bacteria, it is normal to find them in the digestive tract as they are in a symbiotic relationship with our bodies in this area; however, they also cause opportunistic infections in places outside of the digestive tract to our detriment, such as with a urinary tract infection. Some strains of bacteria are common to nosocomial infections, and identifying these bacteria as such helps create the guidelines for healthcare workers in antiseptic technique. All of the morphology and characteristics of each strain of bacteria help us to better understand the role of bacteria in the body as well as helps us understand how they can cause illness, and what treatment regimen to set in place. In lab this semester, a sample of unknown

This particular bacterium is not one that inhabits a specific geographical region as it colonizes within the human body. The disease is

The gram stain test was able to identify the bacterium as a gram-positive organism, and the morphology distinguished it as a strain of streptococcus, and these finds helped direct the other tests. Hemolytic tests are very useful in differentiating specific species of a certain family of bacteria. The hemolytic test showed the bacterium to be of alpha clearing, which meant it only partially lysed the red blood cells and left a greenish tint. This identified the bacterium as either strep pneumoniae or faecalis. The bacitracin test, which tests whether the bacterium is susceptible to the antibiotics in the disk, posted a positive

In the world of microbiology it is vitally important to be able to discern the identities of microorganisms. Not only is it important in a lab setting but as well as in healthcare in general. Properly identify what strain of bacteria a person has will aid in the proper medicine and dose given. Throughout the semester we have learned about different types of bacteria and certain test that can clearly identify them. The purpose of this lab report is to identify a Gram-positive or Gram-negative bacterium. Using all the knowledge of procedures and lab techniques identify the unknown and discuss all the tests you performed.

The identification of unknown bacteria are used in labs by microbiologist for the purpose of studying bacteria that cause diseases, diagnosis of diseases and for treatment of the diseases. Therefore, it is important for them to effectively identify the right bacteria that is causing harm to people, animal or environment and treat it successfully. Hence, discussing the different type of test used and the processes of how one could identify the unknown bacteria.

This condition is characterized by symptoms and complications that result from reflux or back of gastric content into the esophagus that extent also into the oral cavity or even the lungs. Common signs and symptoms of this condition include heartburn( burning/stinging), and does note that radiates to the back such as in the case of Peptic Ulcer Disease (PUD). Furthermore, other symptoms patients may experience are a chronic cough, bronchospasm, chest pain not related to a cardiomyopathy, hoarseness, early satiety, abdominal fullness, bloating with belching. Complications related to this disorder are closely linked to esophageal ulceration, hematemesis, melena, stricture development(Dains, Baumann, & Scheibel,

pylori. However, the second option omeprazole 20 mg twice daily, clarithromycin 500 mg twice daily and amoxicillin 500 mg twice daily, is better for the patient based on cost because it is less expensive and the patient has concerns about medication with less copay.

In conclusion, after conducting previously mentioned biochemical tests in order to identify the unknown bacteria, became obvious that unknown gram negative was Proteus Vulgaris. Having eliminated all the bacteria that didn’t show expected results and confirming with such tests as catalase, glucose, indole, citrate, urea, and SIM, it was accurate to name the unknown gram negative. Furthermore, gram positive became obvious it was Streptococcus Pneumoniae. Having eliminated all the bacteria that didn’t show expected results and confirming with such tests as blood agar, catalase, and optochin and bacitracin tests, it was accurate to name the unknown gram positive. I have learned that it is extremely important to be to able to identify what kind

With the antibiotics if H Pylori is confirmed, what would you educate the patient about these medications?

H. pylori thrives in the acidic environment of the stomach and the finding that this bacteria contributed to the condition was remarkable news and led to the standard practice of treating peptic ulcers with antibiotics. As a result, the rate of H. pylori-induced ulcers has dropped by more than 50 percent. (Ackerman, 2012)

Helicobacter pylori (H. pylori) is a bacterium that inhabits the human stomach and has been linked as a risk factor for chronic gastritis, ulcers, and gastric cancer. H. pylori is able to survive in the acidic environment of the stomach due to its urease enzyme which converts the urea in gastric juice to alkaline ammonia and carbon dioxide. Infection with H. pylori is generally contracted during childhood and can persist indefinitely if untreated. Possible risk factors for H. pylori infection include poor diet, poor hygiene, density, low socioeconomic status (SES), and family history of gastric disease. Studies have found an increased risk of infection with consuming food prepared under unsanitary conditions and a reduced risk with increased consumption of fruits and vegetables. Poor hygiene
