• Pasteurization

• Koch Law´s

• Fermentation Law´s

• Koch Postulates

What does the first koch postulates states?

• “The organism must be present in half cases of the disease”

• “The organism must be absent in every case of the disease”

• “The organism must be present in most cases of the disease”

• “The organism must be present in every case of the disease”

What does the 2nd koch postulate states?

• “The organism must be isolated from a host with the corresponding disease and grown in pure culture”

• “The organism must be isolated from a host with a different disease and grown in pure culture”

• “The organism must be isolated from a host with the corresponding disease and grown in a culture with other bacteria”

• “The organism must be isolated from a host with a different disease and grown in bacteria culture”

What does the third koch postulate states?

• “Samples of the organism removed from the pure culture must cause the corresponding disease when inoculated into a healthy, susceptible laboratory animal”

• “Samples of the organism removed from the pure culture must cause the corresponding disease when inoculated into a sick, susceptible laboratory animal”

• “Samples of the organism removed from the bacteria culture must cause the corresponding disease when inoculated into a healthy, susceptible laboratory animal”

• “Samples of the organism removed from the pure culture must cause the corresponding disease when inoculated into a sick, nonsusceptible laboratory animal”

What does the 4th koch postulate states?

• “The organism must be isolated from the inoculated animal and identified as being different to the original organisms isolated from the initial, diseased host”

• “The organism must be isolated from any animal and identified as being identical to the original organisms isolated from the initial, diseased host”

• “The organism must be isolated from the inoculated animal and identified as being identical to the original organisms isolated from the initial, diseased host”
