Abstract

The aim of this study was to evaluate the specificity of a polymerase chain reaction assay for detecting Brucella DNA using primers specific for the amplification of a 223 bp region of the sequence encoding a 31 kDa immunogenic Brucella abortus protein (BCSP31). DNA from all Brucella strains, including type, reference, vaccine and field strains, were correctly amplified. With the exception of Ochrobactrum spp., no other amplification was detected with a broad panel of microorganisms serologically or phylogenetically related to Brucella spp. This very good degree of specificity, together with its high yield demonstrated in previous clinical studies, confirms that this polymerase chain reaction assay could be a useful tool for the diagnosis of human brucellosis.
