Figure 5.

Heat map representing the antibacterial activity of linear venom peptides from the ants M. rubra and M. ruginodis against seven strains of bacteria. The OD₆₀₀ of triplicate cultures was measured after 24 and 48 h and was normalized to the untreated bacterial controls (set as 100% growth and shown in white). Darker red colors indicate more potent growth inhibition. The antibiotic gentamicin was used as a positive control. The peptides are identified by their short names.
