Cholera is caused by a number of types of Vibrio cholerae, with some types producing more severe disease than others. [2] It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. [2] Undercooked shellfish is a common source. [9] Humans are the only known host for the bacteria. [2]
Some strains of V. cholerae are pathogenic to humans and cause a deadly disease called cholera, which can be derived from the consumption of undercooked or raw marine life species or drinking contaminated water. [2] V. cholerae was first described by Félix-Archimède Pouchet in 1849 as some kind of protozoa.
A cholera outbreak in Syria has already killed at least 33 people, posing a danger across the frontlines of the country's 11-year-long war and stirring fears in crowded camps for the displaced.
Some of these genes also help the bacteria spread more easily and survive in the human gut. That makes it resilient to environmental stress and more efficient at causing disease, the researchers said.
Cholera toxin mechanism. 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] It is a member of the heat-labile enterotoxin family.

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.
The 2010s Haiti cholera outbreak was the first modern large-scale outbreak of cholera—a disease once considered beaten back largely due to the invention of modern sanitation. The disease was reintroduced to Haiti in October 2010, not long after the disastrous earthquake earlier that year, and since then cholera has spread across the country ...
