Figure 2From: Actinobacillus pleuropneumoniaegenes expression in biofilms cultured under static conditions and in a drip-flow apparatusImages of typical static and drip-flow biofilms of A. pleuropneumoniae S4074. Confocal microscopy of A. pleuropneumoniae S4074 4 h-static biofilm and 6 h-static biofilm cultured in a microtiter plate and 4 h biofilm and 28 h biofilm cultured in a drip flow apparatus (A), and a typical biofilm visible after 28 h in the drip-flow apparatus (B). For CLSM, biofilms were stained with the SYTO-9 (live) and propidium iodide (dead) or WGA-conjugated to Oregon green and visualized at 40X for the 4 h and 6 h biofilms, and at 4X for the 28 h drip-flow biofilm.Back to article page
