“…Thus, their diagnosis is included here and we may conclude that in addition to road accidents, habitat fragmentation and grey wolf predation [31,32,33], tick-borne infections may constitute an additional significant limitation on the growth and spread of elk populations in the region. To date, at least three Babesia species (B. venatorum, B. capreoli, B. odocoilei-like) have been found in Eurasian elk [34,35].…”

Introduction and objective. Reports on tick-borne infections in free-living juvenile animals and their impact on survival of cervids in nature are lacking. The aim of the study was to detect and identify the Babesia and Anaplasma phagocytophilum species/ecotypes that may have contributed to the death of juvenile animals from a wildlife rescue centre in spring 2020. Materials and method. PCR amplification and sequencing of two genetic markers (18S rDNA and cox1 for Babesia, 16S rDNA and groEL for A. phagocytophilum) were used for screening eleven samples derived from juvenile animals which died in a rescue centre (seven roe deer Capreolus capreolus, one elk Alces alces, one red squirrel Sciurus vulgaris, one European beaver Castor fiber, one red fox Vulpes vulpes). Phylogenetic analysis of full-length 18S rDNA sequence was performed to enable differentiation between two closely-related species infecting wild ungulates, Babesia capreoli and Babesia divergens (zoonotic).Results. The occurrence of the typical SNPs of B. capreoli at two discriminating positions in the 18S rRNA gene allowed identification of B. capreoli infection in a roe deer calf. In two calves, Anaplasma phagocytophilum ecotype 2 was identified, including the same calf co-infection. No Babesia DNA was amplified in an elk calf treated for babesiosis. Splenomegaly was recorded in roe deer calves with A. phagocytophilum and A. phagocytophilum + B. capreoli infection. Conclusions. The study revealed that tick-borne infections are common among juvenile, free-living cervids and may contribute to their mortality.

“…Nevertheless, Malmsten et al. (2018) found sequences highly similar to B. schoenbuchensis in only 0.7% (4/615) of the moose spleen samples from southern Sweden, an area where deer keds are present. Yet, the employed methodology—a novel high‐throughput real‐time PCR to amplify the ssrA gene—could be less sensitive than those used in previous studies.…”

“…Indeed, because the number of YFV cases was unusually high since January 2016 [34], we added specific detections of YFV strains circulating in South America to screen field-collected mosquitoes from Brazil, French Guiana, Suriname, and Guadeloupe. In conclusion, our method designed to specifically identify MBVs in mosquitoes can be used to screen other types of samples such as human and/or animal blood or organs [35]. We demonstrated the usefulness of this new screening method, which represents a powerful, cost-effective, and rapid system to track MBVs all around the world and could be easily customized to any viral emergence.…”

Mosquitoes are vectors of arboviruses affecting animal and human health. Arboviruses circulate primarily within an enzootic cycle and recurrent spillovers contribute to the emergence of human-adapted viruses able to initiate an urban cycle involving anthropophilic mosquitoes. The increasing volume of travel and trade offers multiple opportunities for arbovirus introduction in new regions. This scenario has been exemplified recently with the Zika pandemic. To incriminate a mosquito as vector of a pathogen, several criteria are required such as the detection of natural infections in mosquitoes. In this study, we used a high-throughput chip based on the BioMark™ Dynamic arrays system capable of detecting 64 arboviruses in a single experiment. A total of 17,958 mosquitoes collected in Zika-endemic/epidemic countries (Brazil, French Guiana, Guadeloupe, Suriname, Senegal, and Cambodia) were analyzed. Here we show that this new tool can detect endemic and epidemic viruses in different mosquito species in an epidemic context. Thus, this fast and low-cost method can be suggested as a novel epidemiological surveillance tool to identify circulating arboviruses.
