Name the different organism morphologies - correct answer-
Coccus
Coccobacillus
Vibrio
Bacillus
Spirillum
Spirochete
Name the bacterial arrangements - correct answer-Coccus
diplococcus
staphylococci
streptococci
sarcina
tetrad
Describe a Filamentous Rod - correct answer-A long string of
bacillus bacteria
, Page | 2
Describe a Fusiform Rod - correct answer-Bacteria that is pointed
on the ends
Describe Pleomorphic Rods - correct answer-Different lengths
and shapes of the same bacteria
What is the melting and liquid temperatures of agar? - correct
answer-Polysaccharide melts at 100C and stays liquid until 45-
50C.
Nutrient Agar - correct answer-The most basic growth media for
bacteria. Examples: TSA and Nutrient Agars
Enriched Media - correct answer-Supplemented with various
substances to encourage growth of fastidious organisms.
Examples: BAP and Chocolate.
, Page | 3
Enrichment Broths - correct answer-Enhance the growth of
specific MOs while inhibiting the growth of others. Examples: GN,
Selenite, LIM and Trans-Vag broths.
Nonselective Media - correct answer-No antimicrobial substances
and allows growth of most organisms. Examples: BAP and
Chocolate.
Selective Media - correct answer-Contains antimicrobial
substances which allows the growth of specific bacteria while
inhibiting the growth of others. Examples: PEA, CNA, MAC, EMB
Microaerophilic - correct answer-Decreased oxygen (5-10% O2).
Example: Campylobacter
Capnophilic - correct answer-Increased CO2 (5-10% CO2)
Example: Haemophilus influenza.
Humidophilic - correct answer-Increased humidity (70-80%)
