Primers and probes Three RT-qPCR assays targeting the non-coding region at the 5’ end (5’-NCR) of HAV which have been described by Costafreda et al. [38], and adapted from Costafreda et al. [38] and Di Pasquale et al. [39, 40] were used. The sequences of the primer pairs and the TaqMan probes used were as follows: The HAV RT-qPCR assay A generates amplification products of 174 bp [38] and was recommended in the CEN/ISO/TS 15216 (qualitative / quantitative methods) for detection of HAV in foodstuffs. The sense primer (HAV68) was 5′-TCACCGCCGTTTGCCTAG-3′, the antisense

primer (HAV241) was 5′-GGAGAGCCCTGGAAGAAAG-3′ and the TaqMan probe (HAV150 -) was 5′-FAM-CCTGAACCTGCAGGAATTAA–MGB-3′. HAV RT-qPCR assay check details NSC23766 mouse B generates amplification products of 353 bp. It exhibits the same sense primer and probe as HAV RT-qPCR model A associated with another antisense

primer named HAV-399R: 5′ -GCCTAAGAGGTTTCACCCGTAG -3′ designed with Beacon Designer software. Finally, the HAV RT-qPCR assay C adapted from Di Pasquale et al. [39, 40] generates amplification products of 77 bp. The sense primer (HAVf ISS (459–478)) was 5′- GCGGCGGATATTGGTGAGTT-3′, the antisense primer (HAVr ISS (535–515)) was 5′- CAATGCATCCACTGGATGAGA-3′ and the TaqMan probe (HAVp ISS (484–511)) was 5′ ROX- Δ GACAAAAACCATTCAACGCCGGAGGACT-BHQ2-3′. When comparing to the model published by Di Pasquale et al. [39, 40], “Δ” corresponds to a deletion of 4 nucleotides and the nucleotides in bold corresponds to insertions. Three RT-qPCR assays targeting the rotaviruses were used. The RT-qPCR assay which has been described by Pang et al. [41] in the NSP3 region was used with a sense primer slightly modified with degenerated bases for matching with both human and simian strains. Thus, RV RT-qPCR assay A generates amplification products of 87 bp. The sense primer (Rota NVP3-F) (positions: 963–982) was 5′-RYCATCTAYRCATRACCCTC-3′, the Tangeritin antisense primer (Rota NVP3-R) (positions 1034–1049) was 5′-GGTCACATAACGCCCC-3′ and the TaqMan probe (positions 984–1016)

was 5′- FAM- ATGAGCACAATAGTTAAAAGCTAACACTGTCAA-BHQ1-3′. RV RT-qPCR assay B generates amplification products of 313 bp. It exhibits the same antisense primer and probe as RV RT-qPCR assay A associated with another sense primer named Rota NSP3-736 F : 5′-GARTGGTATYTAAGATCWATGGAAT-3′ designed with Beacon Designer software. RV RT-qPCR assay C designed in the NSP4 region with Beacon Designer software generates amplification products of 352 bp. The sense primer (rotaNSP4_166-188 F) was: 5′-ATTGCRYTGAAAACRTCAAAATG-3′, the antisense primer (rotaNSP4_517-493R) was: 5′-GCAGTCACTTCTYTTGGTTCATAAG-3′ and the TaqMan probe (rotaNSP4_486-462P) was 5′-ROX-YCCACTTTCCCAYTCTTCTAGCGTT-BHQ2-3′. Primers and probes were purchased from Eurofins (Les Ulis, France) and Applied Biosystems (Courtaboeuf, France).
