“…CSF PCR for Brucella has been proposed for diagnosis and follow up (Pappas et al, 2007), however, it was repeatedly negative in our case. Based on recent reports of 16s rRNA use in neurobrucellosis, albeit with mixed results (Budnik et al, 2012, Renard et al, 2006, Valenza et al, 2006, we used CSF from the initial puncture for 16s rRNA sequencing, which finally allowed us to verify the presence of Brucella spp in the CNS. To the best of our knowledge, this is the first reported case in which the use of CSF 16s rRNA sequencing aided in the diagnosis of seronegative, CSF culture-negative neurobrucellosis.…”
