Deck 24: Alcaligenes, Bordetella Nonpertussis, Comamonas, and Similar Organisms

Question 1

The biochemical description of Myroides is:

A) oxidase-positive, motile, and rapid urease-positive.
B) urease-positive and has a fruity odor.
C) resistant to vancomycin and will grow on MacConkey agar at 42° C.
D) nonmotile and both urea-positive and phenylalanine deaminase-positive.

Answer 1

B
Urea hydrolysis is a key test for Myroides spp., which is also distinguished by production of a characteristic fruity odor.

Question 2

Quality control is set up to determine the validity of cetrimide agar.Which two organisms should be used?

A) Bordetella bronchiseptica and Cupriavidus pauculus
B) Achromobacter denitrificans and Alcaligenes faecalis
C) Achromobacter piechaudii and Bordetella bronchiseptica
D) Centers for Disease Control and Prevention (CDC) Alcaligenes-like group 1 and Cupriavidus pauculus

Answer 2

C
Only A.piechaudii and B.bronchiseptica, both positive and negative for growth on cetrimide agar, respectively, should be used for quality control purposes.

Question 3

Pertussis (whooping cough), an epidemic disease, is a highly contagious, acute infection of the upper respiratory tract caused by the _________ species.

A) Brucella
B) Bordetella
C) Pasteurella
D) Francisella

Answer 3

B
Pertussis is a highly contagious, acute infection of the upper respiratory tract caused primarily by Bordetella pertussis and less commonly by B.parapertussis.

Question 4

Gram-stain morphologic features, motility, and flagellar placement are important identifying characteristics of:

A) Chryseobacterium.
B) Flavobacterium.
C) Pseudomonas.
D) Bordetella.

Question 5

B) The habitats vary from the soil and water environment to the upper respiratory tract of various mammals.
C) The habitats are limited to the soil and water environment.
D) The habitats are limited to the mucous membranes of humans and animals.

Question 6

A) oxidase-positive, motile, and rapid urease-positive.
B) indole-positive, nonmotile, and has a fruity odor.
C) resistant to vancomycin and will grow on MacConkey agar at 42° C.
D) nonmotile and both urea-positive and phenylalanine deaminase-positive.

Question 10

The mode of transmission of Bordetella bronchiseptica can best be described as:

A) person-to-person contact.
B) exposure to contaminated water.
C) inhalation of contaminated air.
D) close contact with animals.
