Module 2 - Bacterial Structure Flashcards
(15 cards)
is viscous (sticky), gelatinous
polymer external to the cell wall, composed of polysaccharide , polypeptide or both
Bacterial glycocalyx
if the substance is organized and firmly attached to the cell wall
Capsule
if the substance is unorganized and only loosely attached to the cell wall, the glycocalyx
Slime Layer
are important in contributing to bacterial virulence; Often protect pathogenic bacteria from phagocytosis by the cells of the host
Capsule
Important component of Biofilms
Glycocalyx
a glycocalyx that helps cells in a biofilm attach to their target environment and to each other; Protects cells within it and facilitates communication
Extracellular polymeric substance (EPS)
causes cholera which attaches to the cells of small intestine
attaches to the surface of the teeth causes dental problems
Streptococcus mutans
Prevent the bacterial cells from rupturing; Point of anchorage for flagella
Cell Wall
Cell wall is composed of?
peptidoglycan
