QUESTION
Abortion at 6 months onward in cattle may occur in?
OPTIONS
(A) Leptospirosis
(B) Brucellosis
(C) Infectious bovine rhinotracheitis
(D) All of the above
ANSWER
(D) All of the above
EXPLANATION
Leptospirosis, brucellosis, and infectious bovine rhinotracheitis can all cause abortion during the later months of bovine gestation. They act through different infectious mechanisms, including fetal infection and placental injury. Because each can be associated with losses from about six months onward, no single disease encompasses the full differential list, and all of the above is the appropriate choice.
