UNIT 2 CELL APPENDAGES/ SURFACE POLYMERS Flashcards
CAPSULE CONTAINING HYALURONIC
ACID
Pasteurella
multocida
Firmly attached to Cell Wall
CAPSULE
CAPSULE CONTAINING POLYSACCHARIDE
● Klebsiella
pneumoniae
● Streptococcus
pneumoniae
● Neisseria
meningitidis
● Haemophilus
influenzae
The capsule protects the bacteria from attack components of
the immune system and also facilitates and maintains
bacterial colonization of biologic and inanimate surfaces
through the formation of ____
biofilms
Why are biofilms important?
● Often difficult to detect
● Resistant to desiccation
● Dissemination
● Tolerant to biocides
Promotes concentration of nutrients
CAPSULE
SLIME LAYER (GLYCOCALYX) containing polysaccharide

- Streptococcus mutans
Not firmly attached to cell wall
SLIME LAYER (GLYCOCALYX
does not function as an effective permeable barrier or add strength to the cell envelope.
CAPSULE
