Further viewing of the bacterial morphologies can aid in the diagnosis of concurrent enterocentesis, particularly in cases in which spore-forming bacteria; spiral-shaped bacteria; yeast, including Y-shaped forms suggestive of Cyniclomyces species; algal organisms; protozoa; or parasitic eggs are seen. We make our preparations in advance from the PreservCyt-fixed material and before or after the formalin fixation step, cover them with a PEG solution as described above. However, staining can sometimes hinder wet-mount evaluation by introducing artifacts (stain precipitate, microbial overgrowth); cannot preserve cellular morphology (a common misconception); and, for those learning urine sediment, can make evaluation of wet mounts with artifacts more challenging than directly visualizing air-dried preparations stained with a routine in-clinic aqueous quick stain. Cytomorphologic comparison between rehydrated air-dried and conventional wet-fixed pap smears. Dry-mount urine sediment slides must be allowed to air dry naturally or by application of a warm air gun (or a hair dryer) on the cool setting before staining; if a slide is not completely dry, the material can wash away in fixative. PMC Two were air-dried for Liu's stain (a Romanowsky stain) and the other two were wet-fixed for Papanicolaou stain. The site is secure. Triton X-100, 0.2% or Tween 20, 0.05-0.2%) before the immunostaining protocol. All data generated during this study are included in this published article [and its supplementary information files].
