The Microbiology of the Vibrio cholerae Bacterium Abstract Cholera is a deadly disease that has caused a worldwide phenomenon throughout history. Its imperative weapon, the Vibrio cholerae bacterium, has allowed cholera to seize control and wipe out a huge percentage of the human population. V. cholerae’s toxins are the primary causes of cholera’s lethal symptoms. The bacterium contains toxins that help it accomplish its job of invading the human system and defeating the body’s powerful immune
Introduction to Microbiology Pathogen paper Vibrio cholera Nazarbayev University Taxonomy and Morphology Vibrio cholerae is a gram-negative bacterium which is causative agent for the diarrheal disease cholera. Vibrio cholerae is a member of the Vibrionaceae family, which is a facultative anaerobic and is capable of respiratory and fermentative metabolism. It does not form spores and its motility is due to the single polar flagellum. Vibrios are highly halophylic and are very sensitive
Produced by the bacteria, vibrio cholerae that creates a toxin that affects the absorption of water in the small intestine, Cholera is an infectious disease. The majority of the bacteria is wiped out by gastric acid when ingested, while the surviving bacteria settle in the small intestine and begin making the toxin that produces the symptoms of Cholera. The toxin created by the bacteria, Vibrio Cholerae, is a exotoxin. Vibrio Cholerae is a member of the Vibrionaceae family of curved gram-negative
Overview Cholera is still an extremely significant disease worldwide with over 5 million cases being reported per year (Ruiting & Reeves, 2002). Cholera is a diarrheal illness that progresses rapidly and is contracted by ingesting the bacterium Vibrio cholerae which causes an intestinal infection (CDC, 2013). In many cases the illness is mild with hardly any symptoms at all, but in some cases it can become severe. Approximately 5 percent of people who are infected exhibit severe symptoms such as extreme
bacterial disease that affects people who live in poor or non-developing countries in which clean water and other sanitation measures are not found (Plaut 1). People usually acquire cholera when they drink water or eat food that is contaminated with Vibrio Cholerae, which is a bacterium that develops and infection in the walls of the small intestine. If left untreated cholera can be fatal in a matter of hours, even if you were healthy before, since it causes severe diarrhea and vomit which can then lead
Vibrio Cholerae and Cholera - The History and Global Impact Abstract Cholera is a diarrhea disease caused by the bacteria, Vibrio Cholera. For centuries, cholera has terrorized the world. There have been seven pandemics since 1817 and many lives have been lost. Even to this day, cholera runs rampant in many areas of the world. The impact cholera has had on the world is enormous. Cholera has caused immense amount of human suffering and economic/social loss since its beginning. But, as time goes
Secretory Diarrhea (Cholera) Abstract: Cholera is an acute, bacterial infection of the small intestine caused by the Vibrio cholerae bacteria. The Vibrio cholerae bacterium, after attacking the human intestine, is responsible for devastating diarrhea resulting in severe dehydration and electrolyte imbalance. The key cause of this is the ADP ribosylation of the human signaling protein Gsα, catalyzed by the cholera toxin, which produces a biochemical cascade. In this review, we will elaborate on
Cholera The disease, cholera, is an infection of the intestines, caused by the bacterium Vibrio cholerae. As stated in Microbes and Infections of the Gut, the bacterium is “a Gram-negative, comma- shaped, highly motile organism with a single terminal flagellum” (105). Cholera is characterized by the most significant symptom that presents with the disease, diarrhea, and victims can lose up to twenty liters of body fluids in a day. Cholera can be a serious disease, due to the serious dehydration
in its early stages as misconceptions replaced science. The common folk, government officials and medical professionals, a bacterium was an unlikely cause of cholera. Preconceived ideas and misconceptions reproduced faster than the bacterium Vibrio Cholerae could multiply in the intestinal canal of its victim. During the health response to cholera, with the help of John Snow, society learned the disease is spread by a bacterium that passes from the sick to the healthy, not by other inclined beliefs
Each day, poverty takes the lives of twenty-two thousand children around the world. Children who live in poverty not only lack money, but also common necessities. They live with constant hunger, dehydration and disease. Moreover, they lack opportunity, education, and hope. Even in this advanced, modern age, children on every continent are affected by the harrowing effects of poverty. Thankfully, Compassion International was founded to release children from the chains of poverty. A particularly
The natural environment encompasses all living and non-living things occurring naturally; that means the air, water, minerals, organisms, and all other external factors surrounding and affecting a given organism at any time P. The term is most often applied to the Earth or some parts of Earth and it is full of natural resources that are necessary for us to live (Johnson et al., 1997). The environment matters because Earth is the only home that humans have, and it provides air, water, foods, and other

words, particles from decomposed matter would become part of the air, and this dirty air spread the diseases. It was an elegant, but incorrect theory and its debunking took place when it was discovered that cholera was spread through a bacterium (Vibrio cholerae) in water. There is where John Snow play his essential roll in the history of epidemiology (Boston University School of Public Health, 2015). John Snow, one of the Fathers of Modern Epidemiology John Snow, born in 1813 in York, England. He was

We used to life in a sinless world before it was cursed. I do believe that Vibrio cholera and all the other disease causing bacteria are a result of the fallen world. Death and disease is a part of life now, but we can improve its situation. People around the world are suffering from uneccery death and suffering due to Cholera
A read that details the historical prevalence of infectious agents prior to mankind’s scientific discovery of our interactions with other species within the broad environment we fulfill, The Ghost Map: The Story of London’s Most Terrifying Epidemic—and How It Changed Science, Cities, and the Modern World is nothing less than fascinating and important for understanding a brief part of the history of global health concerns. My inclination to use fiction storytelling to share my views on topics I am
five million people are attacked by water-borne diseases and over 100,000 of them die. One fatal disease that can kill within hours is cholera. Cholera is a water-borne disease caused by the spreading of toxins throughout the intestines by the Vibrio Cholerae bacterium. Bad hygiene and other unsanitary conditions such as contamination of food and water can result in this unpleasant infection. As stated in the Gale Encyclopedia of Medicine, “contamination starts when a person infected with cholera steps
Robert Koch was a physician and a scientist. According to Blevins and Bronze (2010), his work “launched the new field of medical bacteriology,” and “ushered in a ‘golden age’ of scientific discovery and a new era of public health” (p. E744). Brock (1999) claimed Robert Koch was “one of the most important figures in medical science and was also the founder of bacteriology” (p. xxi). How did one man accomplish so much and impact the world around him in such a profound way? The three areas that
The River Ganges, also known as the Ganga, flows 2,525 km (1,569 mi) from the Himalaya mountains to the Bay of Bengal in northern India and Bangladesh. The Ganges River begins in the Himalayas' Gangotri Glacier.The glacier sits at an elevation of 12,769 feet (3,892 m). The River Ganges flows through the countries of India and Bangladesh. For most of its course the Ganges flows through Indian territory, although its large delta in the Bengal area, which it shares with the Brahmaputra River,
deaths, more quickly than any other epidemic disease of the 1800s. It is an infectious disease that causes severe diarrhea that can lead to dehydration and death if untreated. Eating food or drinking water contaminated with a bacterium called Vibrio cholerae causes cholera. After the first pandemic had diminished throughout Asia by1824, the disease began spreading again from Bengal in 1826. It began with outbreaks in the Ganges River of Bengal and quickly spread throughout most of India. It had moved
organisms such as bacteria, viruses, and parasites spread through polluted water. When people consume polluted water, these pathogenic organisms can move into the body and causes diseases. For example, cholera which is resulted by the bacterium, Vibrio cholerae is perhaps the most devastating of the waterborne bacterial diseases (Abel,
