Figure 5From: malT knockout mutation invokes a stringent type gene-expression profile in Actinobacillus pleuropneumoniae in bronchoalveolar fluidCFU of the wild type strain, and the malT and lamB mutants in different NaCl concentrations. The strains were incubated for 3 h in the salt-containing BHI medium. Before being exposed to NaCl, the strains were grown in maltose-containing BHI. The bars with the same letters on the top do not differ significantly (P < 0.05)Back to article page
