MICR Exam 1 Questions and Answers
agar - Answer--form of enriched media
-polysaccharide that can be found in red algae that is commonly used to prepare solid culture
Amphitrichous - Answer--flagella are at both end of the cell
Archaea - Answer--major group of microorganisms
-they are prokaryotes and tend to live in harsh environments/generally don't cause human disease
Aseptic technique - Answer--Joseph Lister was the first to initiate these techniques to surgery
-this involved using carbolic acid(phenol) to clean hands, wounds and operating room prior to an
operation
-applied the germ theory(microbes cause diseases) to the treatment and prevention of disease
-decreased surgical mortality by 15%
Bacterial Endospore - Answer--produced in times of nutritional deprivation to withstand no still
conditions and facilitate survival -medically significant genera: Clostridium, Clostriodes, Bacillus(KNOW
THESE)
-resists heat, drying, freezing, radiation, chemicals= survival for millions of years
, Biogenesis - Answer--the belief that living things originate from other living things
Budding - Answer-?
Capsid - Answer-?
Capsomere - Answer-?
Cilia - Answer-?
Complex media - Answer--contains at least one component that is not chemically definable
Contrast - Answer--one of the three properties of an effective microscope
-the ability to be distinguished from the surroundings
-we can increase contrast by staining cells/the backround
Creutzfeldt-Jacob disease - Answer-?
Decomposers - Answer-?
Differential stain - Answer-- use two differently colored dyes known as the primary dye and
counterstain dye to distinguish between cell types or parts
-staining techniques tend to be complex and sometimes require additional chemical reagents to produce
the desired reaction
