Postive or Negative?
Gram-Positive Bacteria Stain Color
Gram-Negative Bacteria Stain Color
The primary structure of the cell wall; repeating sugars of N-acetyl glucosamine (NAG) N-acetyl muramic acid (NAM)
polymers of glycerol or ribitol joined by phosphate groups; in the cell wall
Wall teichoic acids
go part way through the wall; protrudes above the wall; gram-positive
go completely through the wall and link to the plasma membrane; protrudes above the wall; gram-positive
a virulence factor; it protrudes from the cell wall; it is required for infection; it is highly susceptible to mutations; gram-positive
found in myobacterium; waxy liquid incorporated into cell wall; makes cell extremely resistant to environmental stress; acts as a barrier against antibiotics & host defenses; gram-positive
between plasma and cell wall; smaller in gram-positive
Enzymes secreted by gram-positive bacteria that inflict damage on host's tissues
Unique Features of Gram-Positive Wall
Thick peptidoglycan; Phospholipid molecules; one membrane; Teichoic acid & lipoteichoic acid
compose the outer membrane of Gram-Negative wall; act as a barrier
compose the outer wall of the Gram-Positive bacterium
Teichoic Acids - present or not present in Gram-negative and Gram-positive?
A lipopolysaccharide endotoxin that stimulates fever
Unique features of Gram-Negative Wall
Thin peptidoglycan; Lipopolysaccharide; Two membranes; Porins
lipid bilayer with proteins embedded; contains enzymes of respiration and ATP synthesis since prokaryotes lack mitochondria
Name differences between Gram-Positive and Gram-Negative: Peptidoglycan, Teichoic Acid, Lipids, Outer membrane, Toxins, Sensativity to Antibiotics
