Probiotic yogurt drink turns your poop different colors to tell you what’s wrong

If you’ve ever hoped that you could self-diagnose a wide range of intestinal issues with rainbow colored poo, E. Chromi might become your new beverage of choice. The probiotic drink is now used just to detect the presence of E. coli, but one day will be able to tell you if you have colon cancer, worms, rotavirus or a stomach ulcer. Magic rainbow poo.

While researchers have so far only suggested that the drink could be used to track the progress of E. coli, they believe that one day it can diagnose conditions like colorectal cancer, worms, stomach ulcer and salmonella just by people looking into the toilet to check the color of their remains.

British designers Alexandra Daisy Ginsberg and James King developed the disease detecting drink by first genetically engineering bacteria to secrete a variety of colored pigments that are visible to the naked eye.

The team had designed standardized sequences of DNA, known as BioBricks, and inserted them into E. coli bacteria. They explain that each BioBrick part contains genes selected from a range of existing organisms that allows the bacteria to produce colors like red, yellow, green, blue, brown or purple.

They explained that by combining these with other BioBricks, bacteria could be programmed to do things like indicate whether water or food is safe to drink or eat by turning red if they sense a toxin.
