“…In order to identify C. abortus in the evaluated specimens, a PCR assay that amplifies an 856-bp product from the intergenic region between the 16S and 23S rRNA genes was carried out according to Silva-Zacarias et al (2009a) o C. Additionally, the efficiencies of the nucleic acid extraction and DNA amplification procedures for the bovine abortion samples were evaluated by a PCR assay employing an internal control. These reactions were carried out with primers BOV1 (5'-ATACGCCTTCATTACCAG-3') and BOV2 (5'-TTGAATGGAGTAGTGCTG-3'), which amplify a 626-bp amplicon from the ND5 gene of bovine mitochondrial DNA (Wosiacki et al, 2005).…”
