Porphyromonas gingivalis challenge of whole blood consumes antioxidants and causes lipid peroxidation. Whole blood was challenged with P. gingivalis (1 × 10⁶ colony‐forming units [CFU]/mL) for 3, 20 and 60 minutes, whereafter plasma was prepared and analysed for total antioxidant capacity (A) and lipid peroxidation (B). Dotted lines indicate basal level in blood. Data are expressed as mean ± standard error of the mean (n = 5). (*P < .05, **P < .01, and ***P < .001). LPS, lipopolysaccharide; mut, mutant; P.g., Porphyromonas gingivalis
