Access to coagulases enhances staphylococcal survival in blood. Monocultures of LAC, Δcoa, or ΔcoaΔvwbp; cocultures of LAC and Δcoa, or LAC and ΔcoaΔvwbp were incubated in heparinized human blood for 45 (dark gray) or 90 (light gray) min and bacterial survival assessed by bacteria enumeration of CFUs on selective agar plates. The labels with only one strain listed are monocultures; the labels with two strains listed are cocultures. The survival profiles pertain to the strain listed outside the parentheses, whereas the strain listed inside the parentheses denotes what it was cocultured with. Data generated from three independent trials (*P < 0.05, one-way ANOVA with post hoc Tukey test based on the 90-min data; error bars denote ±SEM; n = 3).
