Nội dung text Bacterial Smear Preparation and Staining.pdf
BACTERIAL SMEAR • a dried preparation of bacterial cells on a glass slide. • Properly processed smear: – the bacteria are evenly spread out on the slide in such a concentration that they are adequately separated from one another – the bacteria are not washed off the slide during staining, – bacterial form is not distorted.
• Good smears are critical for discerning: • (1) the morphology of cells • (2) the arrangement of cells • (3) internal structures
