How do you prepare a bacterial smear lab report?

Smears preparation from a Solid Medium Using a loop, place one to two loops of water on center of slide. Heat fix the smear over flame of Bunsen burner by rapidly passing slide 3-4 times over flame. Examine each slide for the confluent, whitish film or haze and record your results in the Lab Report.

Which staining method is morphology of bacteria?

The Gram stain is especially useful as one of the first steps in the identification of a bacterial species, since it reveals both the morphology and the Gram reaction of the bacteria. In this exercise, both Gram-positive and Gram-negative rods and cocci of commonly encountered bacterial species will be stained.

What was the simple stain used to view bacterial morphology?

Figure 1: Methylene blue is a simple and direct stain used for determining bacterial morphology (shape and arrangement).

What are the types of staining bacterial smears?

Stains Smear Preparation. Simple Stain. Negative Stain. Gram Stain. Congo Red Capsule Stain. Wirtz's Endospore Stain.

How do you make a bacterial smear for staining?

Culture from solid media: Using a sterile pipette, add one drop of sterile saline or sterile water to the center of the microscope slide. Aseptically pick a small amount of an isolated colony with a loop and gently mix into the drop of sterile saline or water using circular motions. Mix evenly to make a thin smear.

What is the stain for bacterial morphology?

Figure 1: Methylene blue is a simple and direct stain used for determining bacterial morphology (shape and arrangement). It is a cationic dye (positive charge) which stains the cell a blue color. The presence of negatively charged molecules in the cell (like DNA & RNA) causes the cell to stain blue.
