Section 1

Include some current research, with at least one figure showing data.

Regulation of biofilm formation in Vibrio cholerae at high and low cell densities, from http://jb.asm.org/content/190/7/2527.full


Section 2

Include some current research, with at least one figure showing data.

When V. cholerae are grown on casein protein, the prevalence of QS-deficiency increases, while this increase is not observed when glucose is the nutrient source. Retrieved from http://aem.asm.org/content/early/2015/03/23/AEM.00586-15.abstract

Section 3

Include some current research, with at least one figure showing data.

Presence of cholera toxin (red color) in infant mouse intestines. Prior to infection with V. cholerae, mice were treated with A) nothing, B) E coli Nissle or C) E coli transformed to express V. cholerae cqsA. which encodes the enzyme CAI-1. Group D) had no pretreatment or infection. Retrieved from http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2895089/
