Results of biofilm formation and serum resistance. a Analysis of biofilm formation by DH5α and the three transconjugants (DH5α::pM5_NDM, DH5α::pM5_OXA, and DH5α::pM5_NDM + pM5_OXA). Biofilm was stained with crystal violet and quantified by measuring the absorbance at 600 nm. b Number of surviving bacterial colonies from human serum and those from heat-inactivated human serum as a control. We compared the biofilm formation activity and serum resistance statistically using one-way ANOVA with Tukey multiple comparisons test. *, P < 0.05; **, P < 0.001; ***, P < 0.0001
