MLVA genotyping of Chinese human Brucella melitensis biovar 1 2 and 3 isolates

摘要

BackgroundSince 1950, Brucella melitensis has been the predominant strain associated with human brucellosis in China. In this study we investigated the genotypic characteristics of B. melitensis isolates from China using a multiple-locus variable-number tandem-repeat analysis (MLVA) and evaluated the utility of MLVA with regards to epidemiological trace-back investigation.
