Vancomycin resistance due to VanA in an Aerococcus viridans isolate

[3],[4] Accurate species-level identification of isolates from relevant clinical specimens such as blood and abscess material is important in understanding the pathogenic mechanisms of the particular species. Since phenotypic test systems do not always allowed an accurate identification of this group bacteria, additional detection of 16S rRNA gene and cell matrix-assisted laser desorption ionisation time of flight mass spectrometry (MALDI-TOF-MS) analysis are needed besides classical biochemical tests. Is there has any possibility of interspecies transmission of the VanA gene? [...]the location of VanA gene in A. viridans and the relationship of VanA gene between E. faecium and A. viridans will be confirmed by further research.
