Shimwellia blattae (formerly Escherichia blattae) is a species of bacterium, one of two in the genus Shimwellia. It is an aerobic enteric bacterium first isolated from the hindgut of cockroaches. Although it is related to human pathogens, including Escherichia coli, S. blattae is not pathogenic to humans. It is notable for its ability to synthesize vitamin B12 de novo.
