Groups | Grades | Reactivity | Conditions of all cultures |
Vehicle control | 0 | None | Discrete intracytoplasmatic granules, no cell lysis, no reduction of cell growth. |
HDPE control | 1 | Slight | Not more than 20% of the cells are round, loosely attached and without intracytoplasmatic granules, or show changes in morphology; occasional lysed cells are present; only slight growth inhibition observable. |
Silver based dressing control extracts | 1 | Slight | Not more than 20% of the cells are round, loosely attached and without intracytoplasmatic granules, or show changes in morphology; occasional lysed cells are present; only slight growth inhibition observable. |
AgNO3 solution (3.5 µg/mL) | 3 | Moderate | Not more than 70% of the cell layers contain rounded cells or are lysed; cell layers not completly destroyed, but more than 50% growth inhibition observable. |
Silver based dressing extracts (3.8 µg/mL) | 3 | Moderate | Not more than 70% of the cell layers contain rounded cells or are lysed; cell layers not completly destroyed, but more than 50% growth inhibition observable. |
SPU-ZDEC extracts (100%) | 4 | Severe | Nearly complete or complete destruction of the cell layers. |
