Transmission of Mycobacterium orygis (M. tuberculosis Complex Species) from a Tuberculosis Patient to a Dairy Cow in New Zealand

Abstract

Mycobacterium orygis, previously called the oryx bacillus, is a member of the Mycobacterium tuberculosis complex and has been reported only recently as a cause of human tuberculosis in patients of South Asian origin. We present the first case documenting the transmission of this organism from a human to a cow.
