2. In the scientific name Escherichia coli, the name coli indicates the:
a. species.
b. genus.
c. shape.
d. genus and shape.
ANS: A
The binomial system assigns two names; the first name is the genus, and the second name
is the species.

3. Sensitivity testing is used to determine:
a. the susceptibility of a microorganism to antiviral treatment.
b. the patient’s susceptibility to a particular pathogen.
c. a pathogen’s susceptibility to a particular antibiotic.
d. All are correct
ANS: C
“Sensitivity” refers to a test to determine the organism’s susceptibility to certain
antibiotics.

4. Diagnosis of a helminth infection requires a:
a. stool sample for culture on differential media.
b. stool sample for ova and parasite examination.
c. skin biopsy specimen for fluorescent testing.
d. blood sample for tissue culture.
, ANS: B
Diagnosis usually is based on microscopic examination of feces for ova and parasites.

5. Most pathogenic organisms remain viable at temperatures of ____°C.
a. 37°C
b. 0°C
c. 25°C
d. All are correct
ANS: A
Most pathogenic organisms prefer temperatures around 37°C and remain viable for up to
72 hours if held at room temperature or refrigerator temperature (4°C).

Specimens
MSC: CAAHEP: I.P.11.e | ABHES: 9.d
6. An anaerobic organism is most likely to be isolated from a(n):
a. abscess.
b. sputum.
c. skin scraping.
d. throat.
ANS: A
Anaerobic organisms die in the presence of oxygen, so they are more likely to be seen in
deep wounds.

7. An organism that is flexible as far as its oxygen requirements are concerned is called a(n):
a. aerobe.
b. anaerobe.
c. facultative aerobe.
d. facultative anaerobe.
ANS: D
Some bacteria are flexible about oxygen requirements; although they are anaerobes, they
can survive in the presence of oxygen. These organisms are called facultative anaerobes.

8. Tightly coiled, spiral-shaped bacteria are called:
a. spirilla.
b. sarcinae.
c. spirochetes.
d. streptobacilli.
