Vibrio vulnificus from liquid soap
The Isreali outbreak (associated with changes in fish marketing) was reported in Lancet a few times. It was particularly important for identifying biogroup 3. I hope that might be helpful, but I'm not sure it will be. Since it was an important epidemic, I wouldn't be surprised if it was discussed in a visiting lecture by someone who wasn't part of the Isreal Vibrio study group.

I'm not aware of a soap dispenser case for V. vulnificus, but soap dispensers have been implicated in the transmission of other pathogens. Could it have been some other halophilic bacteria, possibly another Vibrio?
