Principle: In a dark field microscope, the object appears bright against a dark background. This is made possible by the use of a special darkfield condenser.
Distribution is defined as the reversible transfer of drugs between body fluid compartments. After absorption, a drug enters the systemic circulation and is distributed in the body fluids.
Staining is necessary to produce color contrast and thereby increase the visibility of the object. Before staining, the fixation of the smear to the slide is done:
• A disease of adult female bovine occurring around the parturition and caused by hypocalcemia, characterized by weakness, recumbency, paresis, shock, and death.
The structure of the organism’s cell wall determines whether the organism is gram-positive or negative. When stained with a primary stain and fixed by a mordant, some bacteria can retain the primary stain by resisting decolorization while others get decolorized by a decolorizer.
