Vibrio cholerae, the bacterium’s full name,lives in both brackish water and drinking water, and, when not causing humandisease,it is undetectable in water Knowing the genomic structure mayprovide more evidence for a theorythat the cholera bacterium plays a necessary role in the aquatic environment, so that eradication of the disease to protect humans may not be possible or wise. Cholera is spread through contaminated water and food (mostly uncooked shellfish), and has caused seven major epidemics worldwide since it spread outside except with sophisticated genetic probes. Scientists don't know howit doesthat, or why. For somereason,the bacterium also breaks down chitin, the primary substancein the shells of crabs and shellfish, and seemsto havea role in controlling the southern Asia for the first time in 1817.
