BIOL 2051 EXAM 3 - LUZAN QUESTIONS WITH 100%
CORRECT ANSWERS.
Widespread antimicrobial drug resistance in microbes is usually _______
Answer - Already present in bacterial populations in low numbers, but gets
selected for when exposure to low dosages of antibiotics happens( like in cattle
industry) and spreads to human bacteria
Which of the following is NOT a nucleic acid based method of identification?
Answer - Rapid test (immunochromatography)
Interfere with transcription Answer - Rifampin
Inhibit synthesis of major metabolite (like folic acid precursor synthesis)
Answer - Sulfa drugs
Inhibit lipid biosynthesis Answer - platensimycin
Influenza virus is able to make huge " leaps" in its evolution from times to times
by successfully " jumping" from an animal host to a human ( such as swine flu) ,
due to ___________ Answer - Genetic shift
When a pathogen from a patient's sample is isolated in a pure culture and
subsequently identified, using various types of microbial medium ( selective or
differential), it's known as Answer - Growth dependent methods
, DNA methods alone (PCR, and sequencing) are not enough to diagnose
pathogens: the golden standard of any pathogen`s duagostic has to be
performed (or at least attempted): to isolate a pathogen in a pure culture with
the use of differential/selective medium Answer - True
______ medium allows only a NARROW group of microbes to grow, and is
made with the use of an inhibitory component Answer - Selective
Debilitating lower respiratory path disorder, has primary and post primary
( chronic) infection, diagnosed by x-rays of chest cavity Answer - Tuberculosis
Bacterial disease affecting respiratory pathways, with bouts of recurring cough,
affects non vaccinated school aged children Answer - Pertussis
Resistance to which antibiotics involves the efflux pump Answer - tetracycline
Some of the virulence factors of pathogenic bacteria are able to be transferred
via HGT (horizontal gene transfer ) since they are ______ Answer - encoded on
a plasmid
Visible clumping of antigen and antibody, easy to perform, used for blood
typing Answer - Agglutination
Involves antibody linked to an Immunofluorescent dye Answer -
Immunofluorescence
Interaction of soluble antigen and soluble antibody to form an insoluble
complex. Requires " fine tuning" patient antibody content via use of serial
dilutions to get it "just right" Answer - Precipitation
