'A One Health Approach for the Control of Tick-borne Diseases'
In the last decades, the emergence of ticks and tick-borne diseases (TBD) has become a public health concern in Europe. In Piedmont region (Northwestern Italy) ticks were rare in the past, especially in mountain areas. However, in the recent years, we have been observing an increase in tick abundance in the environment but also in reported tick-bites and TBD cases in humans. Tick-borne diseases are characterized by complex transmission cycles; thus, an integrated approach is needed. The ‘One Health’ (OH) approach may effectively provide scientific evidence for TBD surveillance and prevention, and support decision makers. This PhD project investigates the presence and abundance of tick vectors and tick-borne pathogens in two natural areas of Piedmont region, recently invaded by ticks, to identify potential risk factors involved in their emergence, and to evaluate their impact on public health. Additionally, we aimed to identify ideal surveillance and control elements based on a OH approach. We recorded a further expansion of Ixodes ricinus in Europe, being maintained at altitudes up to around 1700 m a.s.l. The abundance of I. ricinus was significantly associated with altitude, habitat type and signs of roe deer presence and molecular analyses demonstrated its infection with several zoonotic agents: B. burgdorferi sensu lato, spotted fever group rickettsiae, Anaplasma phagocytophilum, Borrelia miyamotoi and Neoehrlichia mikurensis. Dermacentor spp. ticks were also collected, in particular D. marginatus and D. reticulatus. Rickettsia slovaca and Candidatus Rickettsia rioja, causative agents of SENLAT (Scalp Eschar Neck Lymphadenopathy) syndrome in humans, infected Dermacentor ticks and wild boar tissues, suggesting the greater contribution of wild boar in its eco-epidemiology and dispersion in the study area. We also confirmed that Piedmontese population is exposed to infected tick bites. However, a generalized low awareness was observed among the population; in fact, although most citizens perceive ticks as a health threat, they do not frequently adopt protective measures. This justified the longer duration of tick attachment generally observed in bitten patients (> 24 hours). A serosurvey in wild ungulates was additionally carried out in mountain areas to assess the circulation of tick-borne encephalitis virus. No serum sample yielded positive results, indicating the absence of this pathogen in our territory so far. Notwithstanding, this activity should be maintained in the long term for early pathogen detection and rapid response, since the virus is circulating in bordering areas of the Piedmont.
Regarding tick ecology, this project integrated some investigations about tick symbionts, whose presence is key for tick development and survival. We detected the infection of Francisella-like endosymbionts in Dermacentor spp. which have been previously associated with positive effects in the tick fitness, by providing nutrimental support to ticks. Moreover, a large-scale study was carried out to investigate the infection of Rickettsiella symbionts in I. ricinus populations in Europe, identifying a great diversity within the Rickettsiella genus.
Research on TBD requires the knowledge and skills from different disciplines. However, transdisciplinarity seems to work when structural support is provided by the system; instead, critical elements such as insufficient funding, system decentralization and monodisciplinary approaches threaten the response capacity of the systems. One Health operation and infrastructure aspects can strengthen surveillance systems and could be particularly important in areas of recent spread of ticks and TBD.
