QUESTION
Which of the following triggers multiplication of Brucella abortus organisms?
OPTIONS
(A) Erytol
(B) Ethambutol
(C) Erythymol
(D) Erythretol
ANSWER
(D) Erythretol
EXPLANATION
Erythritol is a polyol present in bovine reproductive tissues and fetal fluids that can enhance the growth and localization of Brucella abortus, contributing to its reproductive tropism. Therefore option D is correct; ethambutol is an antimycobacterial drug, while the other similarly named compounds are not the relevant Brucella growth factor.
