SEM of Vibrio cholerae, an acute bacterial infection of the small intestine, characterized by severe diarrhea and vomiting, muscular cramps, dehydration and depletion of electrolytes. The disease is spread by water and food that have been contaminated by feces of persons previously infected. The symptoms are caused by toxic substances produced by the infecting organism. The profuse, watery diarrhea, as much as a liter an hour, depletes the body of fluids and minerals. Complications include circulatory collapse, destruction of kidney tissue, and metabolic acidosis. Treatment includes antibiotics to destroy the infecting bacteria and restoration of fluids and electrolytes by injection. Magnification unknown.

Cholera Warning Poster, Antofagasta Region, Chile, 2000.
Cholera, a water-borne disease, seems out of place in the extreme aridity of northern Chile, but in fact it can be a serious killer.
"Pudica" is the Latin word for "shy" or "bashful," which is an apt description of the sensitive "Touch-Me-Not." Native to South and Central America, this shade-lover often grows as a weed under trees and shrubs. It is popular among collectors as a specimen plant worldwide, because of its unique sensitivity to touch.
The foliage retracts when touched to prevent consumption by herbivores, and it also exhibits nyctinastic movement, meaning its circadian rhythms affect its leafs to close at night, and re-open during the day.
This trait is present in many other members of the legume family as well.
You can buy seeds for this plant and grow it yourself:
