microorganism - ANSWER *microbe* is an individual living animal or
plant that is so small, it can be seen only with the aid of a microscope.
found everywhere in the environment. *metabolism* (ability to utilize
nutrients), *reproduction* (ability to group to form colonies or of
individual cells to become larger), *irritability* (response to the
environment), *motion* (ability to move from place to place), *protection*
(including spores, mutation, and development of drug-resistant strains).
endemic - ANSWER organisms present all or most of the time in and
on the body
microbiology - ANSWER study of microorganisms
pathogens - ANSWER disease-producing agents
aerobes - ANSWER microorganisms that require oxygen for growth
anaerobes - ANSWER microorganisms that cannot survive in the
presence of oxygen.
parasites - ANSWER microorganisms that live on or within another
living being (the host).
saprophytes - ANSWER live off the organic remains of dead plants and
animals.
pH - ANSWER hydrogen ion concentration; acidity or alkalinity
sterile - ANSWER free from microbial contamination.
, culture & sensitivity - ANSWER test that identifies the pathogenic
microorganism (culture), determines which treatment will eliminate the
microorganism (sensitivity), and monitors the microorganism's response
to the treatment.
cultures - ANSWER used to identify the organism and, in the case of a
pathogen, to then determine ways in which to arrest its growth. grown in
test tubes or on small, flat covered plastic plates called petri dishes.
cold temperatures often significantly slow the growth of microorganisms
- ANSWER why is refrigeration used to control bacterial growth in
food?
high temperatures - ANSWER what usually kill most microorganisms?
many die although moderately diffused light does not affect them -
ANSWER what happens to microorganisms exposed to the sun's
ultraviolet rays?
microbiologists - ANSWER can grow microbes under controlled
conditions in the laboratory in order to study them
culture medium - ANSWER the material in or on which the
microorganisms are placed
algae - ANSWER often found on sunlit water, appearing as green scum
or green cloudy water
fungi - ANSWER include single-cell yeast and multicellular molds. *of
their own*
mycosis - ANSWER an infection caused by a fungus
tinea - ANSWER ringworm
tinea capitis - ANSWER causes a lesion on the scalp
tinea pedis - ANSWER causes athlete's foot
