Measurement of CFUs in lung homogenates by quantitative culture of serial dilutions on blood agar plates. Figure 2A represents the bacterial colonies on blood agar plates between OVA/P.a mice and OVA/Bud/P.a mice observed using a Kodak Image 4000MM. Figure 2B represents CFUs, shown in column configuration. There were significantly more CFUs in OVA/Bud/P.a mice than in OVA/P.a mice (*P<0.05). Control mice receiving PBS only had no observable CFUs (0 CFU).
