ABSTRACT
Rhipicephalus microplus, known as the hard tick, is a vector for the parasites Babesia spp. and Anaplasma marginale, both of which can cause significant financial losses to the livestock industry. There is currently no effective vaccine for R. microplus tick infestations, despite the identification of numerous prospective tick vaccine candidates. As a result, the current research set out to develop an immunoinformatics-based strategy using existing methods for designing a multi-epitope based vaccination that is not only effective but also safe and capable of eliciting cellular and humoral immune responses. First, R. microplus proteins Bm86, Subolesin, and Bm95 were used to anticipate and link B and T-cell epitopes (HTL and CTL) to one another. Antigenicity testing, allergenicity assessment, and toxicity screening were just a few of the many immunoinformatics techniques used to identify potent epitopes. Multi-epitope vaccine design was chosen based on the antigenic score 0.935 that is promising vaccine candidate. Molecular docking was used to determine the nature of the interaction between TLR2 and the vaccine construct. Finally, molecular dynamic simulation was used to assess the stability and compactness of the resulting vaccination based on docking scores. The developed vaccine was shown to be stable, have immunogenic qualities, be soluble, and to have high expression by in silico cloning. These findings suggest that experimental investigation of the multi-epitope based vaccine designed in the current study will produce achievable vaccine candidates against R. microplus ticks, enabling more effective control of infestations.
