Minimal bactericidal concentrations (MBC) of LL-37 against Aggregatibacter actinomycetemcomitans strains
| A. actinomycetemcomitans strain | Origin | MBC 50 (μg/ml) | MBC 90 (μg/ml) |
|---|---|---|---|
| ATCC 33384 | Laboratory strain | 50 | 70 |
| J1 | Clinical isolate | 20 | 70 |
| J2 | Clinical isolate | 10 | 50 |
| J3 | Clinical isolate | 20 | 50 |
| J7 | Clinical isolate | 10 | 50 |
| J11 | Clinical isolate | 70 | >150 |
| J76 | Clinical isolate | 20 | 70 |
MBC50 and MBC90 indicate the minimal bactericidal concentration (MBC) values at which 50% and 90% of bacterial cells were killed, respectively.
