Abstract:
:Twelve bacterial species including Streptococcus uberis, S. parauberis, S. agalactiae, S. dysgalactiae, S. bovis, S. mitis, S. salivarius, S. saccharolyticus, Enterococcus faecium, E. faecalis, E. avium, and Aerococcus viridans were examined for their 16S ribosomal DNA fingerprint patterns. Oligonucleotide primers complementary to 16S rRNA genes were used to amplify by the polymerase chain reaction 16S ribosomal gene fragments from genomic DNAs. The molecular sizes of the amplified 16S ribosomal DNA (rDNA) fragments from the 12 species examined ranged from 1,400 to 1,500 bp. Restriction fragment length polymorphism analysis of 16S rDNA was performed with 11 different restriction endonucleases. All 12 species examined could be differentiated on the basis of characteristic 16S rDNA fingerprint patterns by using the restriction endonucleases HhaI, RsaI, and MspI. A scheme for the differentiation of the 12 species is presented. Eleven isolates representing 11 species were obtained from cows with intramammary infections and were examined by 16S rDNA fingerprinting. All 11 species isolated from cows were differentiated by using HhaI, RsaI, and MspI restriction endonucleases. The results of this study demonstrate the potential application of 16S rDNA fingerprinting for the identification and differentiation of bacterial species.
