definition

Cholera is an infection of the small intestine caused by some strains of the bacterium Vibrio cholerae.

INVENTION

The Spanish bacteriologist Jaime Ferrán i Clúa invented the cholera vaccine in 1885 by using the following method:

  • First, a sample of the bacteria was mixed with broth in a flask.
  • The culture (growth of bacteria in nutrient media) was completed after 6 hours at 37 degrees Celsius.
  • Once the mixture became cloudy, it was ready to be injected as a vaccine
