To Identity acil fast and on need fout bacteria To descrote the inhocal sigraf cance of acid-foot staining 2. Complete the following table with your observations Name of the Bacteria Color of the cells Acid-last/ non acid-last Drawing (color) 3. What might account for the fact that some bacteria are acid-fast and others are non acid-fast? What is the clinical significance of determining whether or not a bacterium is acid-fast?

Answer 1

1.

​​​​​​. To determine if the bacteria contain a waxy material, mycolic acid in their cell walls which is resistant to your immune system.

​​​​​​. To determine the clinical significance of acid-fast staining by identifying acid-fast and non-acid fast bacteria.

Name of the bacterial color of the cells And fast non- Doawing Ceder) acid-fast C Edi Light blue Non-acid fast Mycobactestum tuberculosis Pink Acid fast The common bactor are acid-fast negatnes tead shows light blue or mellkylene blue colour. And acid-fast positie ones shans pink or and colour. The acid-fast bacteria includes M. tuberculosis, M. lepore, Nocandia opp ete.

3. Bacteria that contain mycolic acid show positive result and bacteria does not contain mycolic acid show negative result.

Mycolic acids are glycolipids that shows poor absorption followed by high retention and is found in the waxy cell walls of a group of bacteria of Mycolata taxon such as Mycobacterium tuberculosis, M. leprae etc.

4. The acid-fast stain can determines if a sample of tissue, blood, or other body substance is infected with the bacteria that causes tuberculosis (TB) and other illnesses.
