Fig. 2From: Attenuated Actinobacillus pleuropneumoniae double-deletion mutant S-8∆clpP/apxIIC confers protection against homologous or heterologous strain challengeGrowth characteristics and hemolytic activities of the A. pleuropneumoniae mutants. a The growth curves of the S-8, S-8△clp and S-8△clp△apxIIC strains. Overnight cultures were inoculated into fresh TSB and then incubated at 37 °C. Growth was monitored by OD600 at an interval of 1 h. b Hemolytic activity test for the S-8, S-8△clp and S-8△clp△apxIIC strains.
