A novel multiplex-PCR for the rapid identification of Mycobacterium bovis in clinical isolates of both veterinary and human origin

Abstract

Bovine tuberculosis is a zoonotic disease that not only causes huge economic losses but also poses an important risk for human infection. The definitive identification of a clinical isolate relies on time-consuming, highly specialized and laborious biochemical tests. We have developed a method for the rapid and reliable identification of Mycobacterium bovis and for its simultaneous differentiation from other members of the M. tuberculosis complex. Furthermore, the technique also allowed us to distinguish M. tuberculosis complex members from other Mycobacterial species. The method comprises both a single PCR and a multiplex-PCR and can be confidently applied to samples of both veterinary and human origin.
