From: Biofilm formation by virulent and non-virulent strains of Haemophilus parasuis
Biofilm formation by H. parasuis in a microfluidic system. Biofilm formation under controlled shear force in a BioFlux 200 microfluidic system. Phase-contrast images of typical biofilms of Haemophilus parasuis non-virulent strains MU21-2 and F9, and virulent strains ER-6P and Nagasaki obtained after 24 h of incubation with an inoculum of OD600 of 0.25 and a shear force of 0.5 dyne/cm2.
