Deck 32: Bartonella and Afipia

Question 1

Bacteremia, endocarditis, bacillary angiomatosis, cat-scratch disease, and peliosis hepatitis can all be caused by

A)Afipia felis.
B)Rochalimaea quintana.
C)Bartonella clarridgeiae.
D)Bartonella henselae.

Answer 1

D
All of the conditions listed have been attributed to infection with Bartonella henselae.

Question 2

A common characteristic of the bacterial species Bartonella henselae and Afipia felis is

A)both are believed to cause cat-scratch disease.
B)the ability to grow on chocolate agar but not very well on routine blood (trypticase soy agar with 5% sheep blood) and not at all on MacConkey agar.
C)that primary isolation from clinical specimens is best accomplished using special cultivation conditions.
D)All of the above are correct.
E)None of the above are correct.

Answer 2

D
The two genera, Bartonella and Afipia, are able to grow on chocolate agar and very slowly on blood agar, typically appearing after 12 to 14 days and sometimes requiring as long as 45 days. Neither organism grows on MacConkey agar. Bartonella henselae and Afipia felis cause cat-scratch disease.

Question 3

Trench fever, bacteremia, endocarditis, chronic lymphadenopathy, and bacillary angiomatosis can be caused by

A)Afipia felis.
B)Rochalimaea quintana.
C)Bartonella clarridgeiae.
D)Bartonella henselae.

Answer 3

B
All of the conditions listed have been attributed to infection with Rochalimaea quintana.
