A magnetic resonance imaging (MRI) of the cervical spine revealed a spondylitis of the sixth cervical vertebra surrounded by a prevertebral abscess neighboring the vertebras C5 to C7, completed by a significant infiltrative lesion involving the soft tissues and muscular compartment invading the overall cervical site (Fig. 1).
Phylogenetic tree of 16S rRNA sequences of patient isolate and non-redundant strains with at least 90% homology found in the GenBank database, constructed by using the neighbor-joining method. GenBank accession numbers are given in parentheses.
