The BMJ published this on September 22, 2010:
No, it’s not a new character from a children’s television programme but a knitted interpretation of the bacterium Clostridium perfringens, which can cause gangrene. Gavi Levy Haskell, a high school student planning to study physics at university, came up with the idea of knitting the bacterium in honour of the annual Ig Nobel prize awards, whose theme this year is bacteria. Gavi’s mother, Susan, and Geri Sullivan, a colleague at Improbable Research, the group behind the awards, joined in.
