This video demonstrates the visualization of bacteria in deparaffinized bladder tissue from a urinary tract-infected patient. Fluorescently-labeled probe hybridized with bacterial 16s ribosomal RNAs reveals the tissue-associated bacteria and their distribution, providing valuable spatial insights into their density within the sample.
Protocol
All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. 1. Tissue Preparation for Fixation and Paraffin Embedding NOTE: Biopsies were taken from consenting women undergoing cystoscopy with electro-fulguration of trigonitis for the advanced management of recurrent urinary tract infection (rUTI). rUTI is defined as 3 UTIs in 12 months. Biopsy collection was performed in …
