Prove that cholera surives in water longer as you claim.
** V. cholerae O1 survived for 8 days in plain water whereas in presence of Fe2O3 it survived up to 15 days.**

Effect of iron on the survival of Vibrio cholerae in water.

Effect of iron in the form of ferric oxide (Fe2O3) on the survival of V. cholerae O1 was studied. V. cholerae O1 survived for 8 days in plain water whereas in presence of Fe2O3 it survived up to 15 days. Presence of organic material in the water further promoted the bacterial survival by at least 4 days. There was no difference between the behaviour of El Tor and classical biotype. These results indicate that the presence of iron in water could promote the survival of V. cholerae O1 in water and may play a significant role in the epidemiology of cholera.

**Surprisingly, most strains of V cholerae are harmless organisms that live and multiply in rivers and the open sea. But at some time in its evolutionary history, the O1 strain turned lethal. What caused this deadly transformation? A virus, according to microbiologist Matthew Waldor.**
It seems according to at least ONE microbiologist .. virus IS the underlying cause of BOTH problems ..?
There is not a whole lot of difference in the pathogen underlying Ebola and the pathogen underlying Cholera.
Except that one is a virus, and the other is a bacteria which ics capable of reproducing itself without invading host cells.
Well, there's also the several-orders-of-magnitude difference in size, the fact that cholera survives outside of the body, the fact that mechanism of pathogenesis, the variety of hosts that harbor cholera, the fact that cholera is usually survivable with reasonable supportive care, ....

OOPS. Comparing bacteria and virus. Gotcha.

Do you think that that means that cholera is harmless and the harm is done by an as-yet-unidentified virus?
