Figure 5.
Conjugation ability of pKPC2 from carbapenem-resistant hypervirulent Klebsiella pneumoniae isolates, Singapore, 2013–2014, to Escherichia coli SLC568. Filter matings were performed for 4 h. The conjugation frequency is the number of CFUs of transconjugants divided by the number of CFUs of recipients. Each symbol represents the value for an individual clone (n = 10) from 3 independent experiments. Horizontal bars indicate means and error bars SD. KPC, Klebsiella pneumoniae carbapenemase. ****p<0.0001.
