Achromobacter, Alcaligenes, and Bordetella are all:
a. urea positive.
b. oxidase negative.
c. nonglucose utilizers.
d. lactose fermenters.
C
The genera discussed in this chapter are considered together because most of them are usually MacConkey positive, oxidase positive, and nonglucose utilizers. They are a diverse group of or-ganisms whose specific morphologic and physiologic features are presented later in this chapter in the discussion on laboratory diagnosis.
