摘要
This study investigated the correlation between bla(OXA-51) variants and Acinetobacter baumannii worldwide clonal lineages 1 to 8 (WW1 to -8). The bla(OXA-51-like) genes of 102 A. baumannii isolates were sequenced. Using DiversiLab repetitive-sequence-based PCR (rep-PCR) typing, 92 of these isolates had previously been assigned to WW1 to -8 and 10 were unclustered. Clustering of DNA sequences was performed using the neighbor-joining method and the Jukes-Cantor phylogenetic correction. bla(OXA-51) variants were in good correlation with DiversiLab-defined clonal lineages. Sequence-based typing of bla(OXA-51) variants has the potential to be applied for epidemiologic characterization of A. baumannii and to identify worldwide clonal lineages 1 to 8.
