Vaccination with proteins involved in tick–pathogen interactions reduces vector infestations and pathogen infection

Tick-borne pathogens cause diseases that greatly impact animal health and production worldwide. The ultimate goal of tick vaccines is to protect against tick-borne diseases through the control of vector infestations and reducing pathogen infection and transmission. Tick genetic traits are involved in vector–pathogen interactions and some of these molecules such as Subolesin (SUB) have been shown to protect against vector infestations and pathogen infection. Based on these premises, herein we characterized the efficacy of cattle vaccination with tick proteins involved in vector–pathogen interactions, TROSPA, SILK, and Q38 for the control of cattle tick, Rhipicephalus (Boophilus) microplus infestations and infection with Anaplasma marginale and Babesia bigemina. SUB and adjuvant/saline placebo were used as positive and negative controls, respectively. The results showed that vaccination with Q38, SILK and SUB reduced tick infestations and oviposition with vaccine efficacies of 75% (Q38), 62% (SILK) and 60% (SUB) with respect to ticks fed on placebo control cattle. Vaccination with TROSPA did not have a significant effect on any of the tick parameters analyzed. The results also showed that vaccination with Q38, TROSPA and SUB reduced B. bigemina DNA levels in ticks while vaccination with SILK and SUB resulted in lower A. marginale DNA levels when compared to ticks fed on placebo control cattle. The positive correlation between antigen-specific antibody titers and reduction of tick infestations and pathogen infection strongly suggested that the effect of the vaccine was the result of the antibody response in vaccinated cattle. Vaccination and co-infection with A. marginale and B. bigemina also affected the expression of genes encoding for vaccine antigens in ticks fed on cattle. These results showed that vaccines using tick proteins involved in vector–pathogen interactions could be used for the dual control of tick infestations and pathogen infection.     

Molecular survey of bovine Babesia species in Bactrian camels (Camelus bactrianus) in Mongolia

Bovine babesiosis, which is caused by species of genus Babesia, is a leading cause of considerable economic losses to the cattle industry each year. Bovine Babesia species have frequently been detected in non-cattle hosts, such as water buffalo (Bubalus bubalis), from which the parasites can be transmitted by ticks to cattle. Therefore, Babesia infections should be minimized not only in cattle but also in non-cattle carriers. In the present study, we surveyed the Bactrian camels (Camelus bactrianus) in Mongolia for three clinically significant bovine Babesia species, including Babesia bovis, B. bigemina, and Babesia sp. Mymensingh, which had been detected previously in Mongolian cattle. We screened blood DNA samples from 305 Bactrian camels in six Mongolian provinces for these species, using parasite-specific PCR assays. Our findings showed that the Bactrian camels in Mongolia were infected with all three Babesia species surveyed. The overall positive rates of B. bovis, B. bigemina, and Babesia sp. Mymensingh were 32.1%, 21.6%, and 24.3%, respectively, whereas 52.5% of the surveyed animals were infected with at least one parasite species. We also found that the female Bactrian camels and the Mongolian native camel breed had significantly higher Babesia positive rates than the male Bactrian camels and the Hos Zogdort breed. In Mongolia, cattle and Bactrian camels usually share common pasture lands for grazing; furthermore, tick species infesting cattle also infest Bactrian camels. Our findings, together with these observations, suggest that the tick transmission of bovine Babesia species might be possible between cattle and Bactrian camels. Therefore, strategies for the control of bovine babesiosis in Mongolia should include methods to minimize bovine Babesia species infections in Bactrian camels.

Vaccinomics,the new road to tick vaccines

Ticks are a threat to human and animal health worldwide. Ticks are considered to be second worldwide to mosquitoes as vectors of human diseases, the most important vectors of diseases that affect cattle industry worldwide and important vectors of diseases affecting pets. Tick vaccines are a cost-effective and environmentally friendly alternative to protect against tick-borne diseases through the control of vector infestations and reducing pathogen infection and transmission. These premises stress the need for developing improved tick vaccines in a more efficient way. In this context, development of improved vaccines for tick-borne diseases will be greatly enhanced by vaccinomics approaches starting from the study of tick–host–pathogen molecular interactions and ending in the characterization and validation of vaccine formulations. The discovery of new candidate vaccine antigens for the control of tick infestations and pathogen infection and transmission requires the development of effective screening platforms and algorithms that allow the analysis and validation of data produced by systems biology approaches to tick research. Tick vaccines that affect both tick infestations and pathogen transmission could be used to vaccinate human and animal populations at risk and reservoir species to reduce host exposure to ticks while reducing the number of infected ticks and their vectorial capacity for pathogens that affect human and animal health worldwide.

Control of Rhipicephalus (Boophilus) microplus infestations by the combination of subolesin vaccination and tick autocidal control after subolesin gene knockdown in ticks fed on cattle

Tick subolesin was shown in immunization trials using the recombinant protein to protect hosts against tick infestations. In this study, we demonstrated that subolesin vaccination and release of ticks after subolesin knockdown by RNA interference (RNAi) could be used for the control of Rhipicephalus (Boophilus) microplus tick infestations in cattle and suggested that the combination of these methods could increase the efficacy of cattle tick control under some circumstances. The greatest tick control was obtained when both release of ticks after subolesin knockdown and vaccination were used concurrently. However, modeling results suggested that vaccine efficacy could be increased if at least 80% of the ticks infesting cattle correspond to subolesin-knockdown ticks. The results of this proof-of-concept trial demonstrated the efficacy of the sterile acarine technique (SAT) through production of subolesin-knockdown larvae by dsRNA injection into replete females for the control of R. microplus tick infestations, alone or in combination with subolesin vaccination.
