« Could We Have Started Out as Magnetotactic Bacteria? | Main | Time Lapse Stink (from the Cornell Mushroom Blog) »

It is interesting to know that DMS is an attractant for copepod crustacea. The association reminds me that the work of Colwell et al. showed that an important retreat of the cholera bacillus is in copepods and filtering them out through multilayers of sari cloth is a helpful protective measure in cholera-ridden regions. Is it possible that emission of modest amounts of DMS by bacteria including the Vibrios encourages or facilitates that association. I remember my old Professor who worked in India on cholera would wonder out loud "Where does cholera go in the winter?" Do we now know, and why?
