 | Term | Definition |
| |
virulence factors |
disease-causing capabilities |
| |
reservoir |
a place to live before and after infection. a requirement of successful pathogens |
| |
Pathogenic needs in order to cause disease |
have a reservoir, leave its reservoir and get to the host, successfully invade into the body of the host (entry, establishment, and evade the body's defenses), multiple within the body, leave the host...so the cycle can continue |
| |
examples of human reservoirs |
small pox, measles virus, cold virus, Neisseria gonorrha, Bordetella pertussis, polio |
| |
Bordetella pertussis |
whooping cough |
| |
Neisseria gonnorrhea |
gonnorrhea |
| |
healthy carrier |
before the symptoms of the invader begin to show, this reservoir is infected but has not yet developed the symptoms of it OR they already got sick, recovered and are still passing it in |
| |
sick carrier |
a reservoir that has the sickness and is currently spreading it |
| |
chronic carrier |
a reservoir that is able to harbor the pathogen for months or years and never become sick but still pass it on. ex HIV and AIDS, Hep B, salmonella, and streptococcus pyogenes |
| |
zoonosis |
human disease that is caused by pathogens that are maintained by animal reservoirs. |
| |
Clostridium tetani |
the bacteria that causes tetanus, the deadly disease is caused by a rapidly produced toxin in the warm environment of the human body, these bacteria can remain in the soil...even when conditions are unfavorarable...for years by producing endospores. these spores can ener into the skin |
| |
