© 2016 The authors regret that after publication of the original article, a calculation error was identified. The conversion of molarity of gallium maltolate (GaM) to concentration is incorrect in the manuscript. The calculation was based on an atomic weight of Ga (69.723) rather than the molecular mass of GaM (445.03). Thus, the MIC 50 and MIC 90 after 24 h of growth were 3,560 ng/mL (8 μM) and after 48 h of growth were 14,241 ng/mL (32 μM). The authors would like to apologise for any inconvenience caused.
