An Adolescent With Neurobrucellosis Caused by Brucella abortus Cattle Vaccine Strain RB51

Abstract

We present the case of an 18-year-old female with a 1-month history of fever, headache, and double vision, whose examination revealed papilledema and cranial nerve VI palsy. Blood cultures grew Brucella abortus cattle vaccine strain RB51, which is inherently resistant to rifampin. We discuss the management of the first known case of neurobrucellosis by this strain.
