Figure 3: E. coli 99/14 viability in mixed cultures. (*) Bars represent the concentration of cells of E. coli 99/14 in co-cultures (E. coli + CRL 1412-MCs) and control cultures (E. coli + empty MCs and E. coli in pure culture). Means with a common letter are not significantly different (Fisher´s test, P< 0.05).
