Phagocytosis of capsulated bacteria

thx dr ramzy

what about the question????

although meningococci has acapsule it is seen intracellular in pus cells
how was it phagocytosed????

The answer...

Capsulated bacteria can be seen inside the pus cells although it has a capsule which protect it from phagocytosis

But simply,

If there is an opsonin “ material can facilitate phagocytosis” it can phagocytosed easily

This process occurs as following:

1. Opsonin attach to the surface of the Ag “May be Ab or complement”

2. This opsonin has a receptor on the surface of the phagocytic cell “FC receptor for the Ab & Complement receptor for the complement”.

3. This attachment enables the phgocytic cell to phagocytose the Ag easily.

That’s it.
