Acid-Fast Stain- Principle Procedure Interpretation and
SIMPLE STAIN and the GRAM STAIN. In most microbiological staining procedures, the bacteria are first fixed to the slide by the heat fixed smear (Figure 1). In this procedure living, potentially pathogenic bacteria are smeared on the glass slide and allowed to air dry. Then the slide is heated so that the bacteria are killed and stuck (coagulation of surface proteins) to the slide. This renders...

Gram stain procedure. PRINCIPLE Clinical laboratory regulatory agencies and Good Laboratory Practice regulations require quality control programs. The performance of equipment, reagents, methods, and techniques must be monitored and documented. QC-Slide™Gram Stain Control is a control slide for use with the Gram stain, eliminating the need to maintain in-house stock cultures for preparing windows batch file programming pdf Gram stain permits the separation of all bacteria into two large groups, those which retain the primary dye (gram -positive) and those that take the color of the counterstain (gram -negative).
