Time-killing curves and hemolytic assay of NZ2114. a Time-killing curves of NZ2114 against S. suis CVCC606. S. suis CVCC606 were incubated in the presence of medium alone (CK), in the presence of NZ2114 at 1×, 2×, and 4× MIC, or in the presence of ampicillin at 2 × MIC, three duplicate observations were made; bars represent the standard error of the mean. b Hemolytic assay of NZ2114. The 4% erythrocytes were incubated with different concentration of NZ2114, the 0.9% NaCl and 0.1% Triton X-100 were used as negative and positive controls. Three duplicate observations were made; bars represent the standard error of the mean
