become directly stained. In direct staining‚ the organisms must be fixed by a process such as heat. Fixing the slide prevents the organism form washing off the slide before visualization. This is accomplished by passing a smear of the bacteria through flame. The heat sets the proteins of the organism thus causing the bacteria to attach to the slide. The organism can become damaged from the setting process and the use of heat prior to staining. In indirect staining‚ the negatively charged colored portion
