Figure 1From: Urinary ATP and visualization of intracellular bacteria: a superior diagnostic marker for recurrent UTI in renal transplant recipients?Shed urothelial cell with evidence of intracellular bacteria. Intracellular localization of bacteria was confirmed by staining with acridine orange and counterstaining with crystal violet; viewed using the x60 objective on a fluorescence microscope. Immunocytochemistry with anti-UPIII (FITC; green) confirmed that cells were urothelial.Back to article page
