Capsule Stain. The capsule stain employs an acidic stain and a basic stain to detect capsule production. Capsules are formed by organisms such as Klebsiella pneumoniae. Most capsules are composed of polysaccharides, but some are composed of polypeptides. The capsule differs from the slime layer that most bacterial cells produce in that it is a thick, detectable, discrete layer outside the cell wall. Some capsules have well-defined boundaries, and some have fuzzy, trailing edges.
Urate crystals (commonly called brick stain by doctors) are a combination of calcium and urate, substances normally found in urine. Crystals of the substance often form, leaving a red-orange stain in your baby's diaper â which can be alarming for parents! Any baby can spill urate crystals, though it's more likely when a baby is dehydrated (or even just slightly dry) as the urine becomes more concentrated.
