RESUMO
The Brucella melitensis chronic infection and drug resistance emerged as a severe health problem in humans and domestic cattle. The pathogens fast genome sequences availability fetched the possibility to address novel therapeutics targets in a rationale way. We acquired the core genes set from 56 B. melitensis publically available complete genome sequences. A stringent bioinformatics layout of comparative genomics and reverse vaccinology was followed to identify potential druggable proteins and multi-epitope vaccine constructs from core genes. The 23 proteins were shortlisted as novel druggable targets based on their role in pathogen-specific metabolic pathways, non-homologous to human and human gut microbiome proteins and their druggability potential. Furthermore, potential chimeric vaccine constructs were generated from lead T and B-cell overlapped epitopes in combination with immune enhancer adjuvants and linkers sequences. The molecular docking and MD simulation analyses ensured stable molecular interaction of a finally prioritized vaccine construct with human immune cells receptors.
