Advantages And Disadvantages Of Bacteria

In everyday life we run into millions of microbes. Some of the bacteria is capable of making humans sick. The study of microbes has become very important subject to help stop potential pandemics and ensure proper hygiene. Anthony van Leeuwenhoek was the first scientist who discovered bacteria. In my study of microbiology, I got to choose an unknown bacteria to identify. It is important to start off finding the family of the unknown bacteria and then eliminating one by one the species to know which bacteria it is. By knowing the family, a scientist can save themselves a lot of time by knowing which tests need to be performed for the elimination process. This might seem like a waste of time to one but being able to correctly identify bacteria

It can take a year or more to regain a healthy gut after you take antibiotics, although for many people it can "only" take weeks or months. During all the time you take antibiotics till the time your bacteria are all back again you will feel less than optimal, or even worse, and you're in danger of getting ill due to your weakened immune system. Right after you're done with antibiotics ends, or even while you're still taking them, eat as many vegetables, probiotics and prebiotics (I'll explain those later) as you can to get your bacteria back, and eat as little sugar as possible to encourage more beneficial bacteria to come back then harmful

Helicobacter pylori (H. pylori) is a human pathogen that is responsible for ulcers and stomach inflammation. The organism had been researched by several scientists around the world since 1875; however none of them was successfully culture it. Until 1982, Dr. Barry Marshall and Dr. Robin Warren succeeded in observing the colonies, and thus became the first scientists to discover this bacterium. By self-testing, Dr. Marshall drank a liquid that contained H. pylori culture. A few days later, he got sick with many symptoms such as vomiting and nausea. After ten days, by undergoing endoscopy, he was able to confirm the role of H. pylori in causing gastritis. Then he and Dr. Warren also demonstrated the effect of

Escherichia Coli, located in one of the main organs known as the large intestine, is a type of bacteria that helps digestion. (Trzepacz, Timmons, and Duobinis-Gray, 2016) For Escherichia Coli to remain stable and alive, it needs specific necessities. These needs are known as the following: Energy, vitamins, and similar compounds. Escherichia Coli is found everywhere!

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.

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

: In the field of microbiology, there are times when a sample will contain more than one species of bacteria. The goal is to separate each bacterium and culture them independently from one another to identify them. This was the objective of this lab. Each stock contained two unknown bacterium, and the possible unknowns were Eserichia coli, Enterobacter aerogenes, Enterobacter cloacae, Serratia marcescens, Proteus vulgaris, Klebsiella pneumoniae, Shigella flexneri, Shigella sonnei, and Salmonella enterica. The tests available were MacConkey agar, Endo agar, Hektoen Enteric agar, Tryptone Soya Agar (TSA), carbohydrate sugar broths, Triple Sugar Iron (TSI) agar, decarboxylase broths (arginine, lysine, and ornithine), Simmon’s Citrate Agar, urease

Triple therapy with metronidazole and either bismuth subsalicylate or bismuth subcitrate plus either amoxicillin or tetracycline for 14 days eradicates H pylori infection in 70–95% of patients. An acid-suppressing agent given for 4–6 weeks enhances ulcer healing. Proton pump inhibitors (such as omeprazole) directly inhibit H pylori and appear to be potent urease inhibitors. Either 1 week of a proton pump inhibitor plus amoxicillin and clarithromycin or of amoxicillin plus metronidazole also is highly effective [51].

According to Fitzgerald, Helicobacter Pylori bacteria is found in 90% of the patient with duodenal ulcer (2015). This organism produces beta lactamase, therefore it’s resistance. Patient will need an antimicrobial therapy to eliminate the H. pylori infection and prevent recurrence of the disease in addition to an acid suppression therapy. The treatment therapy is known “standard triple therapy” That includes Proton pump inhibitor as well as clarithromycin and amoxicillin or metronidazole (Das, Sureshkumar, Sreenath & Kate, 2016). If the disease is caused from repeated use of NSAID then the drug of choice is Misoprostol 200mcg four times daily with food until NSAID is discontinued. Another form of treatment if cause does not relate to NSAID

Since then, H. pylori has been almost completely eradicated in western countries, being placed onto the endangered species list. Unfortunately in developing countries, gastric and duodenal ulcers remain huge problems. The lack of access to antibiotics and the emergence of antibacterial resistant strains have greatly hindered efforts to cure the diseases. The controversy is not over, however, as 80% of people infected with H. pylori never develop any gastrointestinal diseases. We need to thoroughly research the bacterium and exactly how it works in order to fully understand the role of H. pylori in stomach diseases. With that information, we will have the means to combat the diseases caused by the bacterium and the lack of the

In the system of the gastrointestinal tract, there are some conditions that can affect quality of life and is common. One of these conditions is called peptic ulcer disease (PUD) or also known as H. Pylori (Helicobacter pylori), which is the bacteria associated with PUD that causes the infection that leads to PUD. Almost two thirds of the world is affected with this infection, unbeknownst to the host (Moscou, page 421). This infection is introduced in the body through contaminated sources of food or water. It also can be transmitted through person to person contact by kissing. Once ingested, buffers are released and the bacteria is able to survive despite the acidic conditions of the stomach. Most people do not produce symptoms of the infection, however, there are some that may experience irritation and tissue damage from overproduction of gastric acids and peptic ulcers. Duodenal ulcers, which form in the upper region of the small intestines, are more common in younger people. Peptic ulcers tend to be more common with age as they are more likely to be infected. This disease is treatable and obliteration of the H. pylori results in ulcer cure and prevention of recurrences (Zoorob, page 243)

types of microbial diseases; i.e. how diseases are caused by microbes. Their types like bacterial, viral, fungal etc.

Probiotics are ingestable microorganisms which gives the consumer a beneficial effect. First coined by the late eli Metchnikoff probiotics are described to be microorganisms which are ingested in small amount to increase the diversity of both flora and fauna inside the human body this reaction in turn affects the adaptation abilities for the human body to react to different surroundings, digest different things, or just improve the antibody or the mechanism that already exists in the human body.
