CHAPTER 13 BSAG WALAY MANGGAWAS ANI SA QUIZ Flashcards
Microbes that engage in mutual or commensal
associations
normal (resident) flora,
indigenous flora
microbiota
a condition in which pathogenic microbes penetrate host defenses, enter tissues,
and multiply
infection
an infection that causes
damage or disruption to tissues and organs
Infectious disease
what are the 4 stages in infection
Contact
Colonization
Invasion
Infection
DIsease
this is when microbes adhere to exposed body surfaces
Contact
this is when Microbes cross lines of defense and enter
sterile tissues
Invasion
this is when Pathogenic microbes multiply
in the tissues
Infection
give me the adverse effects of infection
- morbidity/mortality occur
- results in injury/disruption to tissues
- microbes are established in the tissues
give me beneficial effects of infection
- defenses hold pathogen in check
- colonization with microbiota
- repair of damage
microbes that occupy the body for only short
periods
Transients
microbes that become established
Residents
what term is it called when bacterial flora benefit host
by preventing overgrowth
of harmful microbes
microbial antagonism
occur when normal flora is
introduced to a site that
was previously sterile

transients
which cutaneous population is stable, predictable, less
influenced by hygiene
