Q

process of killing or
removing microorganisms on inanimate
surfaces through the use of chemical

infection producing microorganisms
on surfaces but too toxic to be
applied directly to tissues

A

Disinfectant/Germicide

30

minimum time
required to kill a suspension of organism at
a given temperature in a specified
environment.

A

Thermal death time

38
Q

Chemical produced by a
microorganism that inhibits the
growth of other microorganisms

A

system but does not cause harm to
those who have a healthy immune
system

A

40
Q

are infections that
patients acquire during a course of
treatment in a healthcare facility

A

Hospital-acquired infection /
Nosocomial infection

41
Q

is acquired by persons not hospitalized within
the last year or persons who have not had
