Against all odds: molecular confirmation of an implausible case of bone tuberculosis.

Abstract

We report the use of typing based on a variable number of tandem repeats of genetic elements called "mycobacterial interspersed repetitive units" to clarify a puzzling situation involving a patient with an exceptional case of spondylodiskitis that initially led to the suspicion of a possible event of laboratory cross-contamination with Mycobacterium tuberculosis.
