The sepsis group received a fixed dose of live <jats:italic>Escherichia coli<\/jats:italic> infusion over a 1-hour period (1.8 \u00d7 10<jats:sup>9<\/jats:sup>\/kg colony-forming units). Animals were observed 5 hours after the start of <jats:italic>E. coli<\/jats:italic> infusion. In addition to systemic hemodynamic assessment, we performed conjunctival, sublingual, jejunal, and rectal evaluation of microcirculation by using Sidestream Dark Field (SDF) videomicroscopy at the same time points: at baseline, and at 3 and 5 hours after the start of live <jats:italic>E. coli<\/jats:italic> infusion. Assessment of microcirculatory parameters of convective oxygen transport (microvascular flow index (MFI) and proportion of perfused vessels (PPV)), and diffusion distance (perfused vessel density (PVD) and total vessel density (TVD)) was done by using a semiquantitative method.<\/jats:p>\n                     <\/jats:sec><jats:sec>\n                        <jats:title>Results<\/jats:title>\n                        <jats:p>Infusion of <jats:italic>E. coli<\/jats:italic> resulted in a hypodynamic state of sepsis associated with low cardiac output and increased systemic vascular resistance despite fluid administration. Significant decreases in MFI and PPV of small vessels were observed in sublingual, conjunctival, jejunal, and rectal locations 3 and 5 hours after the start of <jats:italic>E. coli<\/jats:italic> infusion in comparison with baseline variables. Correlation between sublingual and conjunctival (<jats:italic>r<\/jats:italic> = 0.80; <jats:italic>P<\/jats:italic> = 0.036), sublingual and jejunal (<jats:italic>r<\/jats:italic> = 0.80; <jats:italic>P<\/jats:italic> = 0.044), and sublingual and rectal (<jats:italic>r<\/jats:italic> = 0.79; <jats:italic>P<\/jats:italic> = 0.03) MFI was observed 3 hours after onset of sepsis. However, this strong correlation between the sublingual and other regions disappeared 5 hours after the start of <jats:italic>E. coli<\/jats:italic> infusion. Overall, the sublingual mucosa exhibited the most-pronounced alterations of microcirculatory flow in comparison with conjunctival, jejunal, and rectal microvasculature (<jats:italic>P<\/jats:italic>
