Why do we air dry bacterial smears?
Hereof, what is the reason for air drying the bacterial smear?
The bacterial frost is air-dried before staining to fix the bacteria on the slide so that it does not wash away with a subsequent staining procedure. The culture also gets better attachment through air drying on the slide.
Similarly, what is the purpose of a bacterial smear? SMEAR PREPARATION. The preparation of a smear is required for many laboratory procedures, including the Gram-stain. The purpose of making a smear is to fix the bacteria onto the slide and to prevent the sample from being lost during a staining procedure. A smear can be prepared from a solid or broth medium.
Likewise, people ask, what is the purpose of air drying?
Drying helps remove excess water to ensure optimal heat fixation. Air-drying adheres the bacteria to the slide. Air-drying ensures that the smear is thin enough to stain. The air-drying step coagulates the proteins in the bacteria. Drying helps remove excess water to ensure optimal heat fixation.
What is bacterial smear?
A bacterial smear is a thin layer of bacteria placed on a slide for staining.
