Mutant strains of Vibrio cholerae can be isolated that fail to produce cholera. As a microbiologist you may postulate that the defect is related to the following CA. Vibrio cholerae is in the lytic phase CB. Vibrio cholerae is in the lysogenic phase CC. Lack of repressor in the Vibrio cholerae D. Mutations in the phages genes

Vibrio cholerae (the causative agent of the disease cholera) can grow in the intestinal tract of a human, with a generation time of just 20 minutes! If you ingested water contaminated with feces, and just 100 cells of V. cholerae made it through your stomach to your intestine, how many cells would there be 3 hours later? (Assume that there is no lag phase, the cell begins dividing exponentially as soon as it reaches the intestine) Select one: a 100...

Exercise 10.3 Cholera This exercise looks at the symptoms of cholera and how the bacterium causes them. Cholera is often treated by oral rehydration therapy (ORT), and this exercise should also help you to gain an understanding of how this works and the ethics of testing new therapies. 1 The cholera bacterium, Vibrio cholero, releases a toxin that causes intestinal epithelial cells to actively pump out chloride ions into the lumen of the intestine. This causes water loss from the...
