Bacterial Species from Metabarcoding Analysis of Spleen Samples i) Post-sequencing Processing Information concerning the small mammal samples and the positive and negative controls multiplexed in the 16Sv4 and MiSeq sequencing run and MiSeq raw sequences of the 16Sv4 rRNA gene from spleen of small mammal samples The sequencing data and related information are available here: https://zenodo.org/records/12518286 ii) Post-filtering Processing Table of abundance of ASVs for small mammals samples whose spleen have been sequenced This biom file contains the abundance data, representing the number of reads obtained after data filtering, for each ASV from the MiSeq runs and for each small mammal spleen sample (N=1270). It also includes taxonomy information for each ASV (based on the Silva database). The results from the two PCR replicates per sample were summed and filtered using both negative and positive controls. File name: Biom_Spleen_EuropeanASVs_SILVA138.1_Pintail100_2023-03-02.biom1 b.

Orthopoxvirus (Poxv) is detected through IFA serological analyses. Pathogens are labeled as follows: Poxv = Orthopoxvirus. File name: VirusIFA.csv c. Leptospirosis from Lip32 Gene Amplicon qPCR Analysis Presence/absence table for the selected pathogens across individual hosts The CSV file includes presence/absence data for the selected pathogens across individual hosts (N=1549), identified by their unique codes (NCHA-ID number). Pathogenic leptospirosis is detected through the LIP32 gene. Pathogens are labeled as follows: Lept = Leptospirosis. File name: Lepto_Lip32.csv For more information on the pathogens, please see the article https://doi.org/10.1101/2025.06.23.661073 and the associated data: https://10.5281/zenodo.15671364 3.
