QUESTION
Bottle brush appearance in gelatin stab culture is characteristic of the disease?
OPTIONS
(A) Mycoplasmosis
(B) Listeriosis
(C) Staphylococcosis
(D) Glanders
ANSWER
(D) Glanders
EXPLANATION
The bottle-brush appearance in gelatin stab culture is classically associated with Burkholderia mallei, the causative organism of glanders, which shows characteristic growth patterns in suitable media. Mycoplasmosis, listeriosis, and staphylococcosis do not produce this characteristic bottle-brush growth pattern. Therefore, option D is correct.
