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
Disease 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
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
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
the well-known cause of severe losses, affecting fish as well as molluscs and crustaceans. Several epizootics of vibriosis have been reported worldwide (Lightner, 1996). Among the bacteria, vibrio species (i.e. bacteria belonging to the species Vibrio harveyi, Vibrio campbellii, Vibrio parahaemolyticus and Vibrio

From food poisoning in ruined foods, there are many bacteria and germs ; Yersinia, Campylobacter, Bacillus cereus, Vibrio, Vibrio cholera non-O1, Vibrio mimicus, Vibrio fullbiaris, Vibrio fluvialis that come with vomitting, diarrhea, high fever and chills. 2-3 Foodborne illness and prevention measures Foodborne illness is a disease from consuming food that has germs, bacteria, parasite, naturally-occurred
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
Vibrio species are commonly found in culture facilitates all over the world. Vibrio-related infections frequently occur in hatcheries, but epizootics are also common in pond reared fish species. Vibriosis is caused by the gram-negative family Vibrionaceae bacteria. Outbreaks occur when the environmental
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
because it causes illness and death of millions in the third world and in particularly children as mentioned . In this report will refer to the most common types of bacteria cause gastrointestinal tract infection for example , Shigella , Salmonella , Vibrio and Campylobacter (3) . First of all , Shigella is gram negative , nonmotile , non lactose fermenting and H2S production . There are four important species , S. sonnei , S. flexneri , S. boydii and S. dysenteriae is the most serious . Next is Salmonella
the general information, sources of infection and risk factors, symptoms, diagnosis, treatment, and prevention and control will give a further insight on cholera. To start with, the scientific name of cholera is Vibrio cholera. Cholera is caused by a comma-shaped bacterium called Vibrio cholera which is a member of the domain Bacteria and kingdom Eubacteria. Organsims in the kingdom Eubactera are unicellular and prokaryotic meaning they do not have a nucleus. Also, their thick cell walls contain
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
Introduction: Topic: Micro-organisms Question: Does cinnamon and curry inhibit the growth of bacteria? Hypothesis: Cinnamon and curry do inhibit the growth of bacteria. Cinnamon inhibit growth better than curry does. Aim: • To see if cinnamon and curry are potent agents in fighting diseases • To compare the ability to inhibit bacterial growth between curry and cinnamon How: I plan to use agar plates in my experiment. There will be a group of 3 petri-dishes: one with just bacteria, another

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
2.0 SOURCE OF FOOD DETERIORATION AND SPOILAGE Food deterioration and spoilage are undesirable changes occurring in food. Foods take time to lose their natural form though spoilage. The perfect environment for food deterioration is exposed moist food left at room temperature. Cooked food left to cool for a long period of time also will cause food deterioration. The three major causes of food deterioration and spoilage are bacteria contamination, physical contamination and chemical contamination.
science was 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
of the many thousands of different bacteria actually are the culprits. More than 90 percent of the cases of food poisoning each year are caused by Staphylococcus aureus, Salmonella, Clostridium perfringens, Campylobacter, Listeria monocytogenes, Vibrio parahaemolyticus, Bacillus cereus, and Entero-pathogenic Escherichia coli. These bacteria are commonly found on many raw foods. Normally a large number of food-poisoning bacteria must be present to cause illness. Therefore, illness can be prevented
