What are the staining properties used in bacterial classification?
Gram positive and negative
What are the types of reproduction seen in bacteria?
Sporing and non-sporing
Give an example of how biochemistry characteristics can be used to identify different bacterial species
Certain strain of Streptococci aureus release beta-haemolysin (a toxin that causes lysis of RBCs)
What is PCR used for in bacterial classification?
to detect organism-specific sentinel (disease-causing) DNA sequence
What disrupts the synthesis of peptidoglycan in bacteria?
Beta-lactam and glycopeptide antibiotics
What are the main components of Gram-positive cell walls?
Peptidoglycan layer, lipoteichoic acids (LTA)
What are the main components of Gram-negative cell walls?
Thin peptidoglycan layer, lipopolysaccharides (LPS)
What are the properties of lipopolysaccharides (LPS) in Gram-negative bacteria?
O antigen (carbohydrate chain) and endotoxin (lipid A component)
What can Gram-negative bacteria do with larger molecules?
Preliminary digestion in the periplasmic space.
What are the mechanisms that ensure accurate DNA replication?
Base selection, 3’-5’ exonuclease, mismatch repair
