developed four criteria to demonstrate that a specific disease is caused by a particular agent
Koch’s Postulates .
26
Koch’s Postulates (4 items)
1. The specific agent must be associated with every case of the disease. 2. The agent must be isolated from a diseased host and grown in culture. 3. When the culture-grown agent is introduced into a healthy susceptible host, the agent must cause the same disease. 4. The same agent must again be isolated from the infected experimental host.
27
T or F Most infectious agents that cause disease are microscopic in size and thus, are called MICROBES or MICROORGANISMS.
TRUE
28
These are simple single-celled organisms (Prokaryotes) Has no nucleus or membrane bound organelles

31
Multicellular organisms
FUNGI
32

33
How Infectious Agents Cause Disease.
Production of poisons, such as toxins and enzymes, that destroy cells and tissues.
34
TYPES OF TOXINS MICROBES PRODUCE (2 items)
ENDOTOXIN EXOTOXIN
35
These toxins are secreted by the bacteria into host tissues to make a pathogenic change
EXOTOXIN
36
Even with the absence of bacteria these toxins can still remain and still could cause diseases
EXOTOXIN
37
These toxins are part of the cell wall of the bacteria
