Chapter 9 - Infection Control Concepts Flashcards
What is acquired immunity?
What is acquired resistance?
What is airborne transmission?
What are antibodies?
What are antigens?
What are bacteria?
small, singh-celled organisms with a cell wall and an atypical nucleus that lacks a membrane
What is the cycle of infection?
factors involved in the spread of disease:
- infectious organism
- reservoir of infection
- portal of exit
- susceptible host
- portal of entry
- means of transport from reservoir to host
What is direct contact?
What is droplet contamination?
What are droplet nuclei?
What is an endospore?
a resistant form of the bacteria that is produced within the cell when environmental conditions are unfavorable - can germinate when conditions improve
What is a fomite?
What is a fungus?
yeasts or molds that can cause skin or respiratory infections; they may also serve useful purposes
What is a health care-associated infection (HAI)?
What are molds?
multi-cellular fungi
What does it mean to be motile?
capable of motion
What is natural resistance?
What is normal flora?
microorganisms that live on or inside the body without causing infections or diseases
What is a nosocomial infection?
What is an opportunistic infection?
an infection caused by usually nonpathogenic organisms
What is passive immunity?
What is a pathogen?
a microorganism that causes infections or diseases
What are pathogenic organisms?
What is phagocytosis?
What is a prion?
a small, not well understood pathogen that is believed to be an infectious protein
What are protozoa?
complex, single-celled animals that exist as free-living organisms
What is a spore?
the reproductive method for a mold
What is a vector?
What is a vehicle?
What is a virion?
a fully developed viral particle made of genetic material protected by an outer protein coating
What are virulence factors?
