Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Although Koch was convinced that the bacterium was the cholera pathogen, he could not entirely procure critical evidence that the bacterium produced the symptoms in healthy subjects (an important element in what was later known as Koch's postulates). His experiment on animals using his pure bacteria culture did not lead to the appearance of the ...
While most of those affected will have mild or no symptoms, cholera can kill within hours if untreated. A cholera outbreak in Syria has already killed at least 33 people, posing a danger across ...
Cholera toxin (also known as choleragen and sometimes abbreviated to CTX, Ctx or CT) is an AB5 multimeric protein complex secreted by the bacterium Vibrio cholerae. [ 1 ] [ 2 ] CTX is responsible for the massive, watery diarrhea characteristic of cholera infection. [ 3 ]
Symptoms of the disease appear between 12 hours and 5 days of infection; however, only 10% of infected people show severe symptoms of watery diarrhoea, vomiting and leg cramps.
