%X Although mortality caused by Sarcoptes scabiei has been reported in European wild rabbit (Oryctolagus cuniculus) and Iberian hare (Lepus granatensis), there is a lack of detailed information regarding the exposure of wild lagomorph species to this parasite. Here, we aimed to determine the seroprevalence and potential risk factors associated with S. scabiei exposure in European wild rabbits and Iberian hares in Mediterranean ecosystems of southern Spain. Between 2018/2019 and 2021/2022 hunting seasons, serum samples from 464 wild rabbits and 132 Iberian hares were collected from 100 hunting grounds in Andalusia (southern Spain). Sera were tested using an in-house indirect ELISA to detect specific anti-S. scabiei antibodies based on the immunodominant protein Ssλ20ΔB3. The overall apparent individual seroprevalence was 15.9% (95/596; 95%CI: 13.0-18.9). Antibodies against S. scabiei were detected in 11.6% (54/464; 95%CI: 8.7-14.5) of the European wild rabbits and 31.1% (41/132; 95%CI: 23.2-39.0) of the Iberian hares. Species (Iberian hare), age (adults) and geographical area (western Andalusia) were identified as risk factors potentially associated with S. scabiei exposure using generalized estimating equation analysis. By applying spatial analysis, two significant cluster of high seropositivity were detected in western and central Andalusia, respectively. The seroprevalence values obtained provide evidence of endemic, widespread and heterogeneous exposure to S. scabiei among wild lagomorph populations in Spanish Mediterranean ecosystems. Our findings underscore the importance of implementing integrated surveillance programs for sarcoptic mange in wild lagomorphs as well as in other sympatric species.
