epidemic in populations next to zero or regular invulnerability, frequently taking after normal catastrophes amid which the nature of water and sanitation can be traded off (Kim, Mogasale, Burgess and Wierzba, 2015). As stated by Clemens, the bacteria Vibrio cholera that causes cholera disease can be transferred from person to another person by fecal oral route, contaminated water, poor sanitation and hygiene (Kim, Mogasale, Burgess and Wierzba, 2015). On the word of Carpenter, cholera is showed by easy

United States. The United States was able to escape this worry because of effective public health measures and other resources. However, in third world countries such as Haiti, a cholera outbreak is a frequent worry. Cholera is caused by the bacterium Vibrio cholerae, found in contaminated waters. Symptoms of cholera include diarrhea, dehydration, increased heart rate, muscle cramps, low blood pressure, and dry mouth, throat, nose and eyelids (WebMD 2014). In industrialized countries, the implementation

In the TGM, Johnson includes scientific evidence and tangents to enrich the story of the cholera epidemic on London. Johnson tries to get a “bird’s eye view” of seeing how cholera spread through London. In that way Johnson tries to get the reader to not only see individual stories of people who contracted cholera but to produce information on how it came about, what it is, and give as much background and insight to get the reader to see information they usually wouldn’t. Johnson also uses these scientific

It is true that the earthquake exacerbated the water and sanitation problem in Haiti, but in reply to the statement of the sanitation issue of water contamination, cholera started because of feces that got into the Haitian's primary source of water. Being curious of how the water in Haiti became contaminated, I found this article from the New York time which stated that the United Nation accepts responsibility for the cholera outbreak that killed thousands of people in Haiti. It was reported that

Microbiology Case Study: Carmen The disease that is plaguing Carmen is caused by the microorganism Vibreo cholera. V. cholerae is a gram-negative, curved-shaped rod bacterium with a single flagellum. Naturally waterborne, V. cholerae is highly motile which likely enhances its high pathogenicity.1 In 1833, Robert Koch was the first to isolate V. cholerae and explain its transmission.2 V. cholerae is secretes the cholera toxin which invades the human intestinal tract and activates adenylate cyclase

Vibrio fischeri is a Gram-negative bacterium that served as the model organism in this experiment. We isolated only the luxAB portion of the entire lux operon and inserted it into the pGEM vector plasmid to transcribe the luciferase enzyme required for bioluminescence. Within the lux operon, luxAB is responsible for producing subunits that form luciferase, which oxidizes the aldehyde made by luxCDE into the reduced flavin-mononucleotide FMNH2 and results in the production of light known as bioluminescence[6]

Last week, I read an article in the New York Times, called It’s a Slow Death’: The World’s Worst Humanitarian Crisis. It talked about the recent cholera outbreak in Yemen, which killed almost 2,000 people in three weeks and infected over 500,000. The authors have presented three critical graphs in this article. The first one is a thematic map of cholera case density in Yemen. The map shows that western Yemen is the most heavily affected, several parts of which have reached an infection rate of 300

AMINO ACID SEQUENCE ANALYSIS OF THE SUBUNIT B FROM CHOLERA TOXIN PRODUCED BY Vibrio cholerae O139 CELIO CABRAL OLIVEIRA NUCLEOTIDE SEQUENCE ANALYSIS RUTGERS UNIVERSITY FALL 2014 INTRODUCTION Cholera is a tropical disease that causes critical dehydration. The bacterium, which can be found in contaminated water or food, produces the toxin that causes unusual fluid secretion (1). Even though cholera still causes several deaths, about 80% of the cases can be treated with rehydration therapy

Thus, the aim of the experiment is to show the typical phases of growth of a bacterial population, Vibrio natriegens, as well as the calculation of the generation time. Also, this experiment aims to determine how the availability of oxygen affects the growth of a bacterial population, Vibrio natriegens. The population density will be determined turbidometrically. Materials and Methods 12 ml of Vibrio natriegens culture was added to 200 ml of BHI medium contained in a pre-warmed flask (either shaking

first suggested these “vibrios” could be associated with the human enteric disease. King cultured them from the blood of infected individuals and was the first to study this human disease causing “Vibrio” species in depth (King, 1957). She observed that they grew at a distinctly higher optimum temperature than the other vibrios they were grouped with and referred to this subgroup as “related-vibrios” (King, 1957). Sebald and Véron formally separated these “related-vibrios” from the Vibrionaceae family
