FIG 1.
Results of serum resistance assay are shown here as CFU viability. Error bars indicate standard deviations. (A) Serum resistance assay for all CTX-M-producing and non-ESBL-producing K. pneumoniae isolates. Significance is shown for the difference between CTX-M-producing and non-ESBL-producing K. pneumoniae isolates (*, P < 0.05). (B) Survival rate of each non-ESBL-producing K. pneumoniae isolate and its transconjugant after incubation for 2 h.
