Figure 4From: malT knockout mutation invokes a stringent type gene-expression profile in Actinobacillus pleuropneumoniae in bronchoalveolar fluidPercent survival of the wild type strain, and the malT and lamB mutants in porcine serum. The percent survival is the fresh-serum-surviving CFU expressed as the percent of CFU surviving in the heat inactivated serum. The strains were incubated in fresh and heat-inactivated serum for 1 h. The bars with same letters on the top do not differ significantly (P < 0.05)Back to article page
