Mycobacterium bovis infection in a young Dutch adult: transmission from an elderly human source?

Source finding and contact tracing was initiated by the regional municipal health service using both tuberculin skin test and QuantiFERON(®)-TB Gold (QFT-GIT (IGRA). The strain appeared near-identical to that of an elderly Dutch patient.
