Abstract

Aim: Due to the increased level of vancomycin resistance in Enterococci species, an aggressive treatment involving targeted antibiotics is required to manage this frequently occurring infection. Materials & methods: Here, subtractive proteomics and reverse vaccinology approaches were employed to identify potential target and for the prediction of B cell and T cell epitopes against vancomycin-resistant Enterococcus faecalis (VRE V583). Results: The results exhibited the presence of 73 out of 805 non-homologous protein sequences in the proteome which can be employed as unique targets to develop the novel drugs and vaccine to counter the deadly infections caused by this microbe. Conclusion: The identified novel target in VRE V583 will equip our knowledge to design effective vaccine against probable protease EEP proteins.
