ABSTRACT
OBJECTIVE: Epifluorescence microscopy, a methodology for the screening of bodily fluids and tissue specimens for microsporidia species, was directed to evaluate the retention of epifluorescence of fixed and stained specimens over time. METHODS: Thirty samples of stool, bodily fluids, duodenal touch preparations, and biopsies, were tested for the retention of their epifluoresence using the Fungi-Fluor procedure. Specimens were examined under a 330- to 380-nm UV filter at the time of preparation, 3 wk later, and then at monthly intervals for 18 months. All specimens were reevaluated for the presence or absence of fluorescence and any decrement of fluorescence over time. No special preservation techniques were used on any of the slides. RESULTS: All 30 specimens maintained their epifluorescence from the time of slide preparation to 18 month later. No decrement in fluorescence was noted in any sample examined. Accuracy and ease of spore identification was maintained. CONCLUSIONS: Epifluorescence microscopy demonstrates the utility of this technique for archival study of microsporidia-containing specimens over prolonged periods of time.
