License Plate Watch 39

Seen today on a Mercedes-Benz C240: "ISLRE4U"

Hmmm, that was a stumper at first. Then I decided to simply run a search on "islre." Which led to this page, and the indication it is some sort of code for "Lactobacillus reuteri."

So, new search for "Lactobacillus reuteri." Which led to a list of many sites selling related products and many sites dealing with trials of of products that use this "...bacterium that naturally inhabits the gut of mammals and birds."

I think this is likely the longest License Plate Watch post I've written to date. Of course this all assumes that code page I found does indicate the meaning of the "ISLRE" but considering the entire plate, I think it's likely the owner of the car is involved somehow with a product that uses Lactobacillus reuteri.
