    Techniques Used: Isolation

    M. catarrhalis β-lactamase-containing OMVs protect S. pneumoniae (pneumococci [Pnc]) from being killed by amoxicillin. Amoxicillin-susceptible S. pneumoniae ATCC 6303 (106 CFU/ml) was grown with amoxicillin (1 μg/ml) preincubated with either 25 μg/ml β-lactamase-positive OMVs (A and B) or β-lactamase-negative OMVs (B and C). OMVs were isolated from M. catarrhalis KR526 (β-lac+) and Bc5 (β-lac−). Growth was expressed either as relative growth compared to starting concentrations measured as absorbance (OD600) (A and C) or as numbers of CFU (B). The data are presented as means and the standard errors of at least three independent experiments. *, P ≤ 0.05; **, P ≤ 0.01; ***, P ≤ 0.001.
