FIGURE 5

Effects of bacterial exposure on monocyte-derived macrophage (MDM) reactive oxygen species (ROS) release. MDMs from seven COPD patients were exposed to Haemophilus influenzae (HI), Moraxella catarrhalis (MC) or Streptococcus pneumoniae (SP) at a multiplicity of infection of 5:1 or left unexposed (control) for 24 h. Supernatant levels of ROS were measured. Data presented as mean+sem fold change of absorbance compared to unexposed control. ##: significantly above unexposed control (p<0.01).
