aerobic (with oxygen) and anaerobic (without oxygen) conditions.
\A fluorescence microscope shows - ANSWER-Dark background and
fluorescense bacteria (lime green)
\A gram stain has been attempted on an unknown sample, and it was found to
have a high degree of resistance to decolorization. Given this property, which
stain should be attempted next? - ANSWER-Acid-fast staining
\A micrometer is defined as: - ANSWER-10-6
\A patient diagnosed with German measles may additionally experience what

\Alpha hemolysis has... - ANSWER-Incomplete Hemolitic activity
\An individual infected with HIV is placed on anti-retroviral medication. What is
the general purpose of this medication? - ANSWER-As the name suggests, anti-
retrovirals are intended to inhibit (anti) the life cycle of retroviruses (retro).
\An organism that obtains its source of carbon from inorganic molecules such as
carbon dioxide is referred to as a ____________? - ANSWER-Autotroph
, \An unstained sample that cannot be visualized with bright field because
microorganism absorbs very little light - ANSWER-Dark field
\Anthrax causes the skin to look - ANSWER-burned and decayed of the flesh
with a red ring around the wound
\As Streptococcus is catalase negative would it thrive or die in the presence of
peroxides? Why? - ANSWER-Streptococcus would not survive in the presence of
peroxides—it is unable to breakdown peroxides (catalase negative).
\Assuming a fixed ocular, identify the part of the microscope you would adjust
to enhance the magnification of a sample. - ANSWER-Objective
\Attachment - ANSWER-pathogen finds a specific target tissue and adhere.
\Beta Hemolysis has... - ANSWER-Complete hemolitic activity
\Blood agar is which type of medium? Select all that apply. - ANSWER-
Differential, Enriched
