Comparison of multiple-locus variable-number tandem-repeat analysis with other PCR-based methods for typing Brucella suis isolates

Abstract

Multiple-locus variable-number tandem-repeat analysis (MLVA), multiplex PCR, and PCR-restriction fragment length polymorphism analysis were compared for typing Brucella suis isolates. A perfect concordance was obtained among these molecular assays. However, MLVA was the only method to demonstrate brucellosis outbreaks and to confirm that wildlife is a reservoir for zoonotic brucellosis.
