Fig 6. Opsonophagocytosis killing of B. thailandensis.
In vitro opsonophagocytic killing of B. thailandensis E264lux using dilutions of pooled antisera collected from intranasally PBS-, SL3261 (vector)-, and SL3261/p1C3 (vaccine)-immunized BALB/c mice. Plates were read at 120 min following the co-incubation of the opsonophagocytosis assay components. Bars represent mean percentage of killing, and error bars represent the standard deviation. Data were analyzed by the Mann-Whitney U test (P<0.0005 vaccine vs. no sera; P<0.005 vaccine vs. vector).
