Abstract:

Phylogenetic analysis of about 14 strains of Enterococcus, Lactobacillus and Streptococcus was carried out using the nucleotide sequence of the gene for abc (ATP binding protein), The result establish a new phylogenetic tree for the classification of Enterococcus, Lactobacillus and Streptococcus. In comparison with 16s rRNA analysis, the abc sequence indicated a greater evolutionary divergence for the bacteria. Thus, in screening for the presence of bacteria, the abc gene might be a useful tool for differentiating between closely related species of bacteria such as Lactobacillus species. and Streptococcus. At present, 16s rRNA sequence analysis is an accurate and rapid method for identifyieng most unknown bacteria to the genus level because the highly conserved 16Ss rRNA region is easy to amplify; however, analysis of the more variable abc sequence region can identify unknown bacteria to the species level. In summary, we have shown that abc sequence analysis is a useful alternative to 16s rRNA analysis for constructing the phylogenetic relationships of bacteria, in particular for the classification of closely related bacterial species.
