Septic Streptococcus milleri spondylodiscitis. We describe 2 patients presenting lumbar spondylitis due to Streptococcus milleri. In both cases origin was related to preexistent intestinal pathology. Surgical drainage of a collection of pus was necessary in one case. Longterm antibiotic therapy led to full recovery. Despite confused nomenclature Streptococcus milleri must be considered a serious pathogen mainly associated with purulent infection with osteoarticular affinity.
