Fig. 1From: Role of phage ϕ1 in two strains of Salmonella Rissen, sensitive and resistant to phage ϕ1Phage ϕ1 influences biofilm production. a Quantitative and b-d Confocal Laser Scanning Microscopy (CLSM) analyses of biofilm produced by: b RSϕ1-; c RRϕ1+; and d RW bacteria. Bacteria were grown in 8-well chamber slide for 20 h and then stained with LIVE/DEAD reagents. Green fluorescence (SYTO9) indicates viable cells and red fluorescence (PI) dead cellsBack to article page
