Interpretive summary: Adult flies have been shown to be able to carry pathogenic E. coli (such as O157:H7) on their bodies; however, no data has been presented on exposure of flies in other life stages to E. coli O157:H7. This study examined if the larvae of house flies could ingest E. coli in bovine manure, using a bioluminescent E. coli to track locations in the fly where it was primarily located. It was found that house fly larvae can ingest and retain large amounts of E. coli, potentially emerging as an immediate vector of pathogenic E. coli. Further research is needed to determine how easy it is for these larvae to spread E. coli in further contact.
