Abstract

Nucleotide sequence analysis is increasingly being used to identify bacteria. In this work, a PCR assay based on degenerate primers was used to obtain the partial sequence of , the gene encoding translation initiation factor 2 (IF2), in 39 clinical isolates of different . The partial sequence encodes the GTP-binding domain of IF2. Together with sequences from the literature, a total of 15 species, each represented by one to seven strains, was investigated. Phylogenetic analysis yielded an evolutionary tree which had a topology similar to a tree constructed using available 16S rRNA sequences. It is concluded that the inter-species variation of the gene fragment is sufficient for its use in the characterization of strains that have aberrant phenotypic reactions.
