Influence of the phosphoethanolamine transferase PetL on the colistin susceptibility of Pasteurella multocida. A A column chart showing the minimal inhibitory concentration (MIC) values of colistin on different E. coli strains containing plasmid-bearing petL from P. multocida or with or without the corresponding plasmids; B A column chart showing the MIC values of colistin on different Klebsiella pneumoniae strains containing plasmid-bearing petL from P. multocida or with or without the corresponding plasmids; C A column chart showing the minimal inhibitory concentration (MIC) values of colistin on the P. multocida wild type strain (PM-WT), petL deletion strain (PM-ΔpetL), and petL complementary strain (PM-CpetL); D A line chart showing the OD₆₀₀ values of the P. multocida wild type strain (PM-WT), petL deletion strain (PM-ΔpetL), and petL complementary strain (PM-CpetL) in TSB media at different time points
