Principles 1.1 - Exam I Flashcards
Microorganisms of the human body include:
- bacteria
- viruses
-fungi - protozoa
- helminths
A collection of microbial organisms that are present within the human body:
microbiome
Components of the human body microbiome include:
- bacteria
- viruses
- fungi
- protozoa
Why are helminths not necessarily considered microbes?
due to their size
Makes up the vast majority of the human microbiome:
bacteria
List three examples of the various shapes of bacteria:
Cocci- round
Bacilli- rod
Spirilla- corkscrew
Eukaryotic microbes include:
protozoa & fungi
Prokaryotic microbes include:
bactreia
Describe the relationship of parasitic organisms:
not considered a benign relationship
Symbionts that harm or live at the expense of their host:
parasitic organisms
Organisms that live within or on us:
symbionts
Normal microbiota would be considered ____ organisms
commensal organisms
Microbes frequently found on or within the bodies of healthy persons:
normal microbiota
Growth or multiplication of parasite on or within the host:
infection
disease resulting from infection
infectious diseases
Overgrowth of Candida albicans due to changes in homeostasis would be an example of:
endogenous infection
any parasitic organisms that causes infection disease:
pathogen
causes disease by DIRECT interaction with the host:
primary pathogen (frank pathogen)
causes diseases ONLY under certain circumstances
opportunistic pathogen
Give an example of an opportunistic pathogen:
candida albicans
ability of a parasite to cause disease:
pathogenicity
Pathogenicity is often mediated by:
virulence factors
Any component of a pathogenic microbe that is required for or that potentiates its ability to cause disease:
virulence factor
Give two examples of virulence factors:
- a toxin that a pathogen produces
- tropism for certain tissue types
