Raw equine semen was subjected to various treatments containing 20 to 80% seminal plasma in extender, with differing sperm concentrations, to simulate spontaneous loss of SMI.

Cross Breeding Promotes Deterioration of Semen Quality in Cattle Bulls. An advantage of using this method, rather than regular positive stains like methylene blue or carbol fuchsin, is that prior fixation by heat or alcohol is not needed, so the organisms are seen in more lifelike shapes.

Since the surface of most bacterial cells is negatively charged, the cell surface repels the stain. The glass of the slide will stain, but the bacterial cells will not. Nigrosin is a simple and indirect stain used for determining bacterial morphology. The shapes and sizes of the organisms are seen as color-free outlines against the dark background. An advantage of using this method is that prior fixation by heat is not needed, so the organisms are seen in more lifelike shapes. The stain is a suspension of carbon, found in India ink or nigrosin. The carbon particles are negatively-charged, as is the cell membrane.
