In the article, “An Endangered Species in the Stomach” by Martin J. Blaser, he talks about a 60,000 year old bacterium living in the human stomach, named “Helicobacter pylori”. H. pylori was first isolated for investigation in 1982 by Barry J. Marshall and J. Robin Warren. Later researchers discovered that H. pylori was responsible for developing peptic ulcers, breaks in the lining of the stomach, or could also cause stomach cancer. For the past 100 years, there has been decrease in H. pylori bacteria in humans due to the widespread use of antibiotics and improved hygiene. At the same time, the disappearance of H. pylori caused an unexpected rise in the acid reflux disease and a deadly type of esophageal cancer. Making H pylori a vital microorganism to research in order to expand the study of microbiology and its interaction with humans.
According to Blaser, the H. pylori “is a group of extremely varied strains cooperating and competing with one another. They compete for nutrients, niches in the stomach and protection from stresses.” There can be variety of strains found in a single...
The helicobacter pylori bacterium also commonly known as H. pylori is a spiral shaped bacterium that is often found growing in the digestive tract. H. pylori bacteria are found in more than half of the world’s population. The bacteria normally attack the lining of the stomach and the small intestines. Although they are present in many people the H. pylori bacteria is usually harmless. The bacteria are adapted to live and survive in the acidic environment of the digestive tract. Furthermore, H. pylori reduces the acidity of the environment around it to survive and will penetrate the lining of the stomach and small intestines where the mucus lining protects it from the body’s immune cells. H. pylori sometimes can interfere with the body’s immune response to ensure their survival and this causes stomach problems (Flemin & Alcamo, 2007).
Jennifer Ackerman's main focus in her article The Ultimate Social Network, is that of the functions concerning bacteria within humans. Although scientists have had presumptions about humans being proficient in governing their body’s innermost structure, they soon come to recognize the sophistication of our inner space which holds an extensive plethora of bacteria and other microorganisms that lie within each and every one of us. Moreover, scientists' new and emerging view of how the human body operates, and the cause of increasing present-day diseases (i.e. obesity and different autoimmune disorders) are uncovered by analyzing effects of certain microbe species in our bodies. By italicizing on points such as the above, in conjunction with bacteria's genetic variations, and modern computing technology, the author proves that scientists are quickly progressing with the characterization the most prevalent species of microbes, which, in her opinion, is definitely paying off.
Streptococcus pyogenes is thought to live benignly within one in five people, and is thusly one of the most common pathogens among humans. Due to its common
E. Coli and other foodborne illnesses are something that should be of major concern to everybody, becasue nobody is safe from it. It is not something that can be prevented or
still a factor that continuously infects humans. In Foodborne Diseases, it says that “They [Salmonell...
With the earliest recordings coming from the Fifth Century B.C., streptococcus pyogenes, and more frequently, its symptoms have been prevalent among doctors and historians for hundreds of years. The first mentioning of streptococcus pyogenes is to be credited to Hippocrates, in which he describes the relative symptoms of the flesh-eating bacteria in its early stages. Then depicted by Billroth in 1874, patients carrying erysipelas were determined to have this certain bacterial infection. In 1883, the chain-forming bacteria were isolated by Fehleisen; and in the following year, Rosenbach applied the S. pyogenes name. Further advances in hemolytic and non-hemolytic studies were made by Lancefield in the 1930’s, in which the alpha, beta, and gamma subgroups of the hemolytic structures – detailed and defined by Schottmueller and Brown - were divided into serotypes.

Over the years humans have tried every possibility to overcome the health problems, spread of epidemics and infections, disease control and have worked towards a healthy society free of disease and health problems. They have succeeded to a great extent. The book “Good germs, bad germs” describes that though the life expectancy is now far more as it was in previous eras. Epidemic problems and infectious diseases are now getting lesser and lesser and humans are being treated successfully. The hygienic conditions have also been improved so as to ensure least growth of microbes, germs, parasites and bacteria. Antibiotics have been invented to address diseases and infections caused by bacteria and viruses. With all these substantial efforts the biologists, physicians and scientists have triggered another epidemic which is even more severe. They have killed those microbes and bacterial species which were human friendly and as a result of either their disruption or mutation, pathogenic bacteria have even become more active and resistant to treatments. This has led to increased ineffectiveness of antibiotic drugs, low immunity and various infections and inflammatory diseases. The chlorinated water for drinking and food processing along with excessive hygienic conditions indicates our fight against these bacteria and germs. Further, these antibiotics are even given to the livestock which becomes our food and as result many of their resistant germs end up in our digestive tract and other organs. Thus, the war against microbes through excessive cleanliness and use of antibiotics has resulted in antibiotic resistance among humans, which has become one of the prominent problems of medical science
Every human has microbiomes that are personalized for the individual and are extremely important to maintaining a good health standing, however, these microbiomes can be capable of contracting a disease. One of the most common areas for these microbiomes to contract something that could be harmful to the person’s health is called the oral microbiomes, which are found in the mouths of humans. Within the biofilms of the oral cavity, rests these oral microbiomes that maintain a healthy equilibrium in the mouth. However, if not taken care of properly, oral microbiomes can be taken over by a pathogen that can quickly turn the state of the person’s mouth from a healthy equilibrium to a very unhealthy equilibrium (1). Some bacteria found in the oral cavity can be an extremely danger.
Unending weakness, untimely maturing, joint inflammation, poor skin and hair quality, danger, hypersensitivities, growth, and numerous different ailments can all outcome from flawed assimilation since poor processing meddles with supplement breakdown, ingestion and digestion system; permits poisons to stay in the body and aggregate; and over anxieties the body. The gastrointestinal framework assumes a focal part in safe framework homeostasis. It is the primary course of contact with the outer environment and is over-burden each day with outside jolts, now and again hazardous as pathogens (microscopic organisms, protozoa, parasites, infections) or harmful substances, in different cases exceptionally helpful as nourishment or commensal vegetation. The critical position of the gastrointestinal framework is affirmed by the colossal measure of invulnerable cells that dwell inside it. Without a doubt, gut-related lymphoid tissue (GALT) is the noticeable piece of mucosal-related lymphoid tissue (MALT) and speaks to right around 70% of the whole safe framework; also, around 80% of plasma cells [mainly immunoglobulin An (IgA)- bearing cells] live in GALT. GALT communicates entirely with gastrointestinal capacities in a dynamic way; for example, by expanding intestinal penetrability in replay
Per the Dictionary.com definition, Dysentery is an infectious disease marked by inflammation and ulceration of the lower part of the bowels, with diarrhea that becomes mucous and hemorrhagic. Some people feel that dysentery isn’t a serious disease. However, in the early 1800s, some areas were almost completely wiped out by this disease.
Salmonella enterica typhi (typhoid fever causing bacteria) are parasites with no other known living environment outside of humans (Pike, 2014). Typhoid has the ability to cause large outbreaks and the Centers for Disease Control and Prevention (CDC) has classified Salmonella species with other food safety threats as high priority potential bioterrorism agents (Baggier, Burwen, Haber, & Ball, 2004). Salmonella enterica typhi is one of three species of the Salmonella genus. Typhoid gets its name from Typhos, which means smoke, or to cloud, or vapor. It was thought to be transmitted through a “cloud of sickness called miasma” (Pike, 2014). When someone recovers from typhoid fever, about 3-5% become carriers o...
What is Foodborne Illness? According to a medical dictionary, foodborne illness is an acute gastrointestinal infection caused by consuming food contaminated with pathogenic, bacteria, toxins, viruses, prions or parasites. Such contamination was caused by improper food handling, preparation or storage of food. Contacts between food and pests, especially flies, cockroaches and rodents are a further cause of contamination of food. Foodborne illness can also be caused by adding pesticides or medicine to food or consuming or by accidentally consuming naturally poisonous substances. That is why foodborne illness can also be called food poisoning.
The most commonly recognized food borne infections are those caused by the bacteria Campylobacter, Salmonella, and E. coli 0157:H7, and by a group of viruses called Calicivirus, also know as the Norwalk viruses. “Thousands of types of bacteria are naturally present in our environment, but not all bacteria cause disease in humans.” (Schmutz 1)
The patient has experienced fever, chills on body, headaches and anorexia as well as sweating especially during the night. The patient has also been feeling fatigued, muscle aches and nausea as well as vomiting especially after eating (WHO, 2010, p. 117). These symptoms started forty eight hours ago, and the patient has not taken any medication except for some aspirin.
