Microbiology: Lab exam 1 Flashcards
Lab coat, gloves, open sink, autoclave
BSL-2
Lab coat, gloves, protective lab clothing, protective pressure personal suit, separate decontaminated facility.
BSL-4
primary lenses, magnify the specimen.
objective lense
magnifies the image formed by the objective lenses.
ocular lens
controls the amount of light.
diaphragm
light source
illuminator
transmits the image from objective lens to ocular lens
body tube.

bacteria
bio-safety level for most introductory microbiology labs
BSL-1
bio-safety level for clinical microbiology lab working with airborne pathogens.
BSL-3
metric unit used to express the size of most bacteria.
micrometer
lens used with immersion oil.
100x
why is immersion oil used?
prevent loss of resolution due to light refraction.
OOOOOO bacteria
Streptoccous
o0o bacteria
coco-bacilli
~~~~ bacteria
spirillum
hanging drop is used to study
motility
aseptic technique refers to?
carrying out a procedure with minimal chance of cross-contamination.
round colony shape
circular
spider colony shape
filamentous
advantage of growing bacteria on a slant
storage, easier to handle
branched growth pattern
