| Strain | Confluent growth halo diam (mm) with:
|
Albod | |||||
|---|---|---|---|---|---|---|---|
| SS-Fe | FeSO4 | FeCl3 | Hemin | DFb | FCc | ||
| BPSM | 0 | 9 | 9 | 21 | 27 | 27 | S |
| BPEP98 | 0 | 0 | 0 | 0 | 0 | 0 | R |
| BPLOW | 0 | 7 | 7 | 21 | 27 | 26 | S |

a
The diameters of confluent growth halos around wells filled with SS-Fe or the indicated iron source (15 μM solution in SS-Fe) were measured in millimeters after 24 h at 37°C. Results are the means for two separate experiments.
b
DF, desferal (ferrioxamin B).
c
FC, ferrichrome.
d
Sensitivity (S) or resistance (R) to albomycin.
