Document Summary

Max von pettenkofer committed suicide because of cholera morbus ( cholera of death ), but not because of the disease itself, but his failed theory of it factor in air, x, when united with factor in soil, caused cholera. 1835: cholera swept across russia and into munich (pettenkofer"s home city) where public water was filthy and drank by the poor (died by diarrhea and fever). Epidemic began in slums, the poor suffered the most, but the rich suffered as well. Cholera was believed to travel by air. Pettenkofer thought it was caused by filth, laziness, and neglected hygiene unhealthy environment. John snow said that the pump in the neighbourhoods most affected had white flocculent particles ; Pettenkofer dismissed snow"s findings because he did not take soil into consideration.

Many laws have been passed in an effort to improve health and welfare of people. Some of these laws were passed in the 1800s requiring sanitary sewers, which ended cholera outbreaks and other epidemics that had killed millions.

The gram-negative bacterium Vibrio cholerae produces a protein, cholera toxin, that is responsible for the characteristic symptoms of cholera: extensive loss of body water and Na through continuous, debilitating diarrhea. If body fluids and Na are not replaced, severe dehydration results; untreated, the disease is often fatal. When the cholera toxin gains access to the human intestinal tract it binds tightly to specific sites in the plasma
membrane of the epithelial cells lining the small intestine, causing adenylyl cyclase to undergo prolonged
activation (hours or days). (a) What is the effect of cholera toxin on [cAMP] in the intestinal cells? (b) Based on the information above, suggest how cAMP normally functions in intestinal epithelial cells. (c) Suggest a possible treatment for cholera.
