What are 3 ways by which bacteria can overcome, evade or avoid phagocytosis? 3pts

Answer 1

Ans:

The 3 ways by which bacteria can overcome, evade or avoid phagocytosis are as follows:-

1. Contact of phagocytes can be avioded by remain in a region inaccessible to phagocytes, ability to respond to irreversible inflammation and production of chemical that inhibit phagocyte chemotaxis.

2. Phagocytic engulfment is inhibited by polysaccharide capsule, M-protein, fimbriae, O polysaccharide, surface slime and K and Vi-antigen.

3. Kill the phagocytes and survive inside the cell, prevent the fusion of phagocytic lysosomes with phagocytes and escape from the phagocytes after rupturing its membrane.
