Figure 2: Evolution of cell density and phage titer after disaggregation of 24-hour biofilms of S. aureus IPLA 1 formed in the absence or presence of phiIPLA-RODI.

From: Low-level predation by lytic phage phiIPLA-RODI promotes biofilm formation and triggers the stringent response in Staphylococcus aureus

Figure 2

(A) Percentage of the initial OD600 after 6 hours of incubation for biofilms grown without phage or in the presence of phage at an MOI of 10−5. (B) Phage titer determined before and after 6 hours of incubation at 37 °C in biofilms formed in the presence of phiIPLA-RODI at an MOI of 10−5. White and black bars correspond to phage titer of the matrix and the adhered cells, respectively. Values represent the average and standard deviation of 3 independent biological repeats. *P-values < 0.05.
