The vaccination represents optimum method evaluated with effective cost to prevent economic losses and to increase the duration and quality of life of the production animals. . Diverse vaccines are produced from the intestinal protein Bm86 of the Rhipicephalus. (B.) microplus. The knowledge of the conservation of the gene bm86 is very important to evaluate the vaccine efficiency and the possibility of reaction crossed between different species of ticks. Samples of R. (B.) microplus come from different localities had been sequenced. The analyses of multiple alignments of the sequences had been made through the BioEdit program 7.0.5.3 version and the verification of polymorphism for visual inspection. In this work the alignment of all was become fulfilled sequences using itself BLAST in the search for similarity. Similarity was observed enters the sequenced fragments of R. (B.) microplus with the sequence of the protein Rs86 de Rhipicephalus sanguineus and with protein HA98 of the tick Hyalomma anatolicum anatolicum. The results give molecular support to synthetic the vaccine use based in the gene bm86 (SBm7462®) to be used in different species of ticks.

Background And Aims: Ticks are blood-feeding ectoparasites that transmit pathogens to animals and humans. One of the most important hard ticks in animals is , which transmits and spp. Although many potential tick vaccine candidates have been identified, no effective vaccine that can provide sterile immunity against tick infestations has been developed.

Article Synopsis
- - The text discusses the significant threat that genetic diversity in ticks poses to livestock health and agricultural economies globally, highlighting their adaptability to various environments and hosts.
- - It reviews three key genetic markers—COX1 gene, ribosomal genes, and microsatellites—used to study tick genetic diversity, emphasizing the strengths and limitations of each marker in species differentiation and population studies.
- - The implications of genetic diversity for vaccine development, particularly the Bm86 vaccine, and the understanding of synthetic pyrethroid resistance in ticks are also addressed, underscoring the need for tailored genetic approaches in tick management strategies.
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.

The control of ticks through vaccination offers a sustainable alternative to the use of chemicals that cause contamination and the selection of resistant tick strains. However, only a limited number of anti-tick vaccines have reached commercial realization. In this sense, an antigen effective against different tick species is a desirable target for developing such vaccines.

Tick and tick-borne disease control have been a serious research focus for many decades. In a global climate of increasing acaricide resistance, host immunity against tick infestation has become a much-needed complementary strategy to common chemical control. From the earliest acquired resistance studies in small animal models to proof of concept in large production animals, it was the isolation, characterization, and final recombinant protein production of the midgut antigen Bm86 from the Australian cattle tick strain of () (later reinstated as () ) that established tick subunit vaccines as a viable alternative in tick and tick-borne disease control.
