WebApr 11, 2016 · The PNA FISH ® YTL assay applied to non-blood clinical specimens (three urine cultures, four catheter tip cultures, and two peritoneal fluid cultures) was performed using a 0.5 McFarland suspension of the yeast isolate from growth on the subcultured plate. The testing was done according to the instructions, using 10 μl of suspension. WebThe PNA probe is fluorescently labeled and binds to species-specific 16S ribosomal RNA. Once a blood culture turns positive, a Gram stain is performed and based on the results the appropriate PNA FISH test is selected. A drop from the positive blood culture is fixed onto a microscope slide. WebPNA-FISH assays have been developed for identifying and diagnosing infectious diseases in a rapid manner within the clinic. Combined with traditional gram staining of positive blood cultures, PNAs can be used to target species-specific rRNA (ribosomal RNA) to identify different strains of bacteria or yeast.
