Evidence

Peer-reviewed

Geography

Stelvio National Park, Italian Alps

System

Ticks; cervid hosts; surveillance

## WHAT THE EVIDENCE SAYS

Sera from 201 red deer harvested in two seasons in 2017–2019 were tested for antibodies to the Ixodes-associated endosymbiont Midichloria mitochondrii. Calves had lower response rates than older deer, and samples differed among park areas, consistent with spatially heterogeneous prior tick contact.

## WHY IT MATTERS / OUR READ

Wildlife serology can prioritize where to deploy direct tick counts and pathogen testing when landscape-scale surveillance is sparse.

## CAVEATS / UNCERTAINTY

Antibodies cannot identify where or when every contact happened, establish present-day tick density or prove infection with a human pathogen. This is an accepted peer-reviewed article awaiting final formatting.
