Definition
| describes an organism's potential to cause infection or disease |
|
|
Term
|
Definition
| pathogens capable of causing disease in healthy persons with normal immune defenses |
|
|
Term
| Define: Opportunistic pathogens |
|
Definition

used to determine ability to establish in host and cause damage |
|
|
Term

|
|
Term
| Process of a Disease: From portal of entry to portal of exit |
|
Definition

Adhesion
Invasion
Multiplication
Infection of Target
Disease
Portal of Exit |

|
Term
|
Definition
microbe enters body
cutaneous or membranous boundary
outside or latent infection |

Term
|
Definition
Microbes gain more stable foothold at portal of entry
Once stable, and attached, pathogen invade body compartment |
