EAEC Under StressLoss of Biofilm Formation
Enteroaggregative Escherichia coli is an emerging foodborne pathogen as a significant diarrheal pathogen in multiple population groups. However, the associated phenotypic changes by which EAEC bacteria survive acid conditions, is not completely understood.
