Helicobacter Research Paper

Vibrio bacteria are Gram-negative with straight or curved rods. These bacteria are motile and have one polar flagellum that has a sheath around it. They occur in both marine and fresh water habitats. There are different factors to include when trying to grow this bacteria. In order for the different species of the Vibrio genus to grow, they need to be in salt or sea-water based medium for optimal growth and can grow in temperatures varying from 10C to 37C. Vibrio bacteria are facultative anaerobes that are non-spore formers. Their classification scheme from domain to genus or largest to smallest consists of: Bacteria, Proteobacteria, Gammaproteobacteria, Vibrionales, Vibrionaceae, and Vibrio (Bay Science Foundation, Inc 2004-09).

The history of Helicobacter pylori goes back to 1875 when German scientists found the spiral shaped bacteria in the stomach linings of patients (“Helicobacter Pylori,” Wikipedia). However, Helicobacter pylori, also known as H. pylori, was officially discovered in 1982 by Barry Marshall and Robin Warren when they ended up leaving petri dishes incubating over Easter weekend (“Helicobacter pylori,” Wikipedia). After returning to the petri dishes after five days they discovered they had unintentionally successfully cultured the bacteria and were finally able to visualize it (“Helicobacter pylori,” Wikipedia). Until 1989, Helicobacter pylori was called Campylobacter pylori (“Helicobacter pylori,” Wikipedia). However further research done in 1989

Citrobacter Freundii is a species of bacteria that can be potentially harmful to humans. It is known to cause meningitis by protruding into the brain and replicating itself (1). The Citrobacter species has also been found as a cause of some urinary tract infections, diarrhea, and even gastrointestinal diseases and symptoms (3). C. Freundii can be located in a wide variety of soils and water (3). Lastly, it is also the cause of many nosocomial infections due to its presence in water (1).

In 1899, Thiercelin found a new gram positive diplococcus that he named enterocoque, suggesting that he believed that this bacterium had something to do with the intestines. He also described finding this bacterium in patients who had enteritis, appendicitis and meningitis (Murray). In 1906, Andrewes and Hoarder isolated this same bacterium from a patient suffering from endocarditis and they also discovered a relationship with urinary tract infections. They named it Streptococcus faecalis, again because of similarities to the human intestinal tract (Murray). Other early 20th century instances of infection where S. faecalis has been associated but not known to be definitively causative include wound infections after World War I, osteomyelitis,

The Centers for Disease Control and Prevention has reported between 8,000 and 18,000 cases of Legionnaires' disease annually in the United States, caused by the spread of the Legionella bacteria. What can you do to protect your facility by preventing Legionella and other waterborne pathogens? Here are five practices you can implement to protect your patients, employees, and facility by preventing bacterial outbreaks in your facility water system.

Bacteria are among the most abundant of all organisms on earth. Some species of bacteria is always present in every different environment the plant has to offer. For this to be possible, bacteria are all very different from one another. This lab aimed to identify a certain colony of bacteria, using a variety of tests at the disposal of scientists. The simplest method of narrowing down possibilities involves the use of a compound microscope to observe the general shape of the cells. The shapes of the bacteria can be Bacilli, Cocci, or Spirochete. This helps to further narrow the possibilities of what the bacterial species is.

The primary goal of this lab was to notice the bacteria growth in each tube/plates and to be able to properly inoculated the media to get a good result.

Escherichia albertii is an emerging gram-negative discretional rod that has been related to multiple cases of human diarrheal disease, especially in young children. The purposes of this study were to illustrate the antibiotic resistance traits and the growth of individual strains of E. albertii on raw ground beef at different storage temperatures.

Campylobacter -like organisms can produce an enterocolitis/proctocolitis syndrome in homosexual males, who are at increased risk for Helicobacter cinaedi and Helicobacter fennelliae infections. C jejuni infections may also produce serious bacteremic conditions in individuals with AIDS. Most reported bacteremias have been due to Campylobacter fetus fetus infection. Campylobacter lari, which is found in healthy seagulls, has also been reported to produce mild recurrent diarrhea in children.Campylobacter upsaliensis may cause diarrhea or bacteremia, while Campylobacter

Pseudomonas Aeruginosa is a bacteria often found in the environment. It is the most common nosocomial infection affecting people with weak immune systems. Pseudomonas infections are usually spread by medical equipment which are not properly cleaned and by the hands of the medical workers. It can be prevented by washing your hands correctly and by conducting environment screening. They are typically treated with antibiotics. However, they are becoming multi-drug resistant.

Helicobacter pylori (H. pylori), which was discovered in 1983 and is a spiral-shaped bacterium that is found in the gastric mucous layer or adherent to the epithelial lining of the stomach (B. J. Marshall & Warren, 1984). The infection of H. pylori is a common and significant public health problem. It affects more than half of the adult population worldwide (Parkin, 2004). In most individuals, H. pylori infection can be asymptomatic throughout life. However, its persistence may cause chronic gastric inflammation and tissue damage, leading to even more severe gastric diseases. Approximately 20% of infected subjects will develop severe gastric diseases such as peptic ulcers, gastric

Acute infection can give an upper gastrointestinal illness with nausea and pain; vomiting and fever may be present also. The acute symptoms may last for less than 1 week or as long as 2 weeks. Once colonized the H pylori infection persists for years and perhaps decades or even a lifetime. About 90% of patients with duodenal ulcers and 50–80% of those with gastric ulcers have H pylori infection. H pylori also may have a role in gastric carcinoma and lymphoma [51].

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.

Bacteria are single-celled microorganisms. Their cell structure is very unique because they don't have a nucleus, and most bacteria have cell walls similar to plant cells. They come in different shapes including rods, spirals, and spheres. Some bacteria can "swim" around using their tails called flagella. Others just stay still or move with the others. Most bacteria aren't dangerous, but some can make us sick. These bacteria are called pathogens. Pathogens can cause diseases in animals and plants. Some examples of pathogens are food poisoning, pneumonia, and tetanus. This online
