From: Endotracheal tube biofilm translocation in the lateral Trendelenburg position
Scanning electron micrographs of the internal surface of the endotracheal tube (ETT) in animals mechanically ventilated for 24, 48, 48 hours with concomitant lung injury and 72 hours. Note in all pictures consistent presence of stage III/IV biofilm, characterized by multiple rod-shaped bacteria embedded within an extracellular polymeric substance. PIG 50, frontal view of the ETT lumen (magnification × 3,000); PIG 30, cross-section of the ETT lumen (magnification × 1,500); PIG 51, frontal view of the ETT lumen (magnification × 3,000); PIG 44, frontal-view of the ETT lumen (magnification × 3,000); PIG 40, frontal view of the ETT lumen (magnification × 3,000); PIG 37, frontal view of the ETT lumen (magnification × 3,000); PIG 48, frontal view of the ETT lumen (magnification × 3,000); PIG 31, frontal view of the ETT lumen (magnification × 3,000).
