a Area under t he reflectivity curve. The second phase area (injection of mAb, 12–22 min) was 4 times greater than the first phase (injection of bacteria, the conventional technique, 0–12 min), respectively. b Sandwich tests (mAb + bacteria + mAb). Decreasing concentrations of Y. pestis (CFU/mL) were tested by the sandwich technique, PBS + mAb was used as negative control. mAb concentration was 1 mg/mL. Asterisk represents a statistically significant difference with PBS + mAb.
