Study Notes
- Physical methods involve heating pathological material to 70-80°C to separate spores from non-spore species
- Vegetative forms are destroyed without harming spores
- Sowings are made on culture media suitable for the development of respective species
- Chemical methods involve adding bactericidal or bacteriostatic substances to culture medium
- Substances are inactive for the bacterial species to be isolated
- Selective media is prepared and used based on this principle
- Biological methods involve inoculating pathological material in animals sensitive to bacterial species to be isolated
- Animal organism acts as a biological filter, destroying saprophytic germs at the entrance gate
- Pathogenic species multiplies, causing death of the animal
- Pure culture is obtained by sowing samples from corpses on culture media.
