Microbiology Questions and answers
Microbiology - correct answer-the science that studies living organisms that cannot be seen
with the naked eye.
Pathogen - correct answer-a disease-producing microorganism
Aerobic microbes - correct answer-microbes that can only live in the presence of oxygen
Anaerobic microbes - correct answer-Microbes that grow best in the absence of oxygen
Antiseptics - correct answer-Solutions that are applied directly to the skin and prevent or
slow the growth of pathogens.
Disinfection - correct answer-A process that uses strong chemicals such as bleach solution
and zephirin to kill pathogens. These chemicals are used mainly on objects and not on the
skin.
Sterilization - correct answer-A process used to kill microbes and their spores.
Bacteria - correct answer-single-celled or noncellular spherical or spiral or rod-shaped
organisms lacking chlorophyll that reproduce by fission
Fungi - correct answer-plant like organism that lives on dead matter
Protozoa - correct answer-tiny animals that are found in contaminated water supplies and in
decayed materials
Rickettsiae - correct answer-parasites that must live inside the cells of other living
organisms. They are transmitted by the animal the parasites inhabits, such as fleas, lice, and
ticks.
Viruses - correct answer-the smallest of all the microorganisms. They can grow and
reproduce only inside other living cells, and are difficult to destroy
non-pathogen - correct answer-microbes that benefit humans and the environment
Cocci - correct answer-round in shape
bacilli - correct answer-rod shaped
spririlla - correct answer-corkscrew or spiral shaped
diplococci - correct answer-cocci occur in pairs or two circles
streptococci - correct answer-cocci occur in chains
