Figure 3. Expression of the cdiBAIEC93 gene cluster induces auto-aggregation.
A) Strains CH9604 (bamAEco) and CH9591 (bamAECL) that carry plasmid pCH12732 were grown in LB medium with and without IPTG, then adjusted to OD600 ~ 0.6 for auto-aggregation assays. B) Photograph of the cell suspensions from panel A after four h of incubation without shaking.
