  • Cholera
    • Structure and roles and bacterial cell
      • Cell wall - Physical barrier, protects cell, controls entry and exit of material
      • Capsule - Protects from other cells, helps bateria stick together
      • Cell-surface membrane - differentially permeable layer, controls entry and exit of material
      • Flagrllum - aids movement, helps cell spin through fluids
      • Circular DNA - contains genetic information for replication
      • Plasmid - posses genes which aid survival e.g enzymes.
    • Prokaryotic
      • No nucleus
      • No nucleolus
      • Circular DNA no chromosomes
      • No membrane bound organelles
      • Smaller ribosomes
      • No ER or golgi
    • Eukaryotic
      • Distinct nucleus
      • Nucleolus
      • DNA located in chromosomes
      • Membrane bound organelles
      • Larger ribosomes
      • ER and golgi and lysosomes
    • How cholera causes disease
      • Symptoms - diarrhoea and dehydration
      • Most killed in stomach acid, some survive, enter the small intestine, produce toxic protein,chloride ions move into the lumen, water potential decreases, water moves into the lumen.
      • Transmission - ingestion of infected water.
