Study Notes
Bacterial Cell Structure
- Capsule is a slimy coating of the bacterial surface that often plays a role in preventing phagocytosis of bacteria.
- Peptidoglycan is one structure of the bacterial cell wall.
Flagella Structure
- Flagella are usually several times longer than the bacterial cell and are composed of a protein called flagellin.
Protozoa Structure
- The outer surface layer of some protozoa is a pellicle.
Protista Reproduction
- Protista reproduces by fission, fragmentation, or conjugation.
T. cruzi Life Cycle
- Infective stage: blood trypomastigote
- Diagnosis stage: blood examination
- Host: humans and animals
Bacterial Cell Wall Differences
Gram-Negative Cell Wall
- Has a thin peptidoglycan layer
- Has an outer membrane containing lipopolysaccharides
- Has a periplasmic space between the peptidoglycan layer and outer membrane
Gram-Positive Cell Wall
- Has a thick peptidoglycan layer
- Lacks an outer membrane
- No periplasmic space between the peptidoglycan layer and plasma membrane
