dspB and katA are required for polymicrobial synergy with Sg. Murine abscesses were formed using Aa WT (Aa), katA⁻, dspB⁻, and Sg. At 3 d postinfection, abscesses were harvested for enumerating viable bacteria on selective media. Each data point represents a single animal, and at least two biological replicates were performed for each condition. Aa percent survival (y axis) was calculated by dividing the number of viable bacteria recovered from the abscess by the number of viable bacteria measured in the inoculum (10⁷–10⁸ cfu). Horizontal bars represent the mean. ns, not significant by a two-tailed Mann–Whitney U test. **P < 0.01; ***P < 0.001 by a two-tailed Mann–Whitney U test.
