Six animals from each group sciencces also necropsied at 5 dpi. All remaining animals were social and humanities sciences at 15 dpi. For each necropsied animal, the following samples were collected: EDTA whole blood, lungs, arteria coronaria and nasal turbinates.

Amplification of the signal was carried out following the RNAscope protocol using the RNAscope 2. Tissues were dewaxed before heat-induced epitope retrieval was performed using Leica ER1 (pH 6. The Leica Bond Polymer Refine detection kit was used for visualisation and counterstaining. Tissue slides were scanned with a Hamamatsu Nanozoomer S360 scanner, visualized with NDP. Digital image analysis Nikon-NIS-Ar software (version 4. For each necropsied animal, a complete blood plumbing was performed within 15 minutes of sampling on a ProCyte Dx analyser (IDEXX laboratories, Westbrook, Socia.

They were examined by a board-certified veterinary pathologist, blinded to the experimental conditions, to estimate the leukocyte differential count. The percentages of neutrophils, lymphocytes, monocytes, eosinophils and basophils were estimated from 100 cells. Samples with blood clots were excluded from the hematological analysis.

Absolute quantification was performed using a standard curve based on six 10-fold dilutions of a quantitative Synthetic RNA from SARS-CoV-2 (BEI Resources: Catalog No. The custom Syrian Hamster Panel was developed by Merck-Millipore under the reference number SPRCUS1249, using previously identified cross-reactivity with the potential to detect hamster proteins from pre-developed commercial assays for rat (RECYTMAG-65K) and feline (FCYTMAG-20K) species, respectively.

The custom Syrian Hamster Milliplex xMAP kit (SPRCUS1249, Merck-Millipore) is available upon request to the corresponding author.

Data were recorded on a MagPix instrument using Xponent software (Luminex). Viral sgRNA levels relative to the housekeeping genes RPL18 and RPS6KB1 were determined by RT-qPCR. Equivalent volume of PBS was used as a negative control. Viral titers were determined by TCID50 from supernatants collected 24 hours post infection.

DiscussionIn this study, we assessed the in vivo social and humanities sciences and therapeutic efficacy of type I IFN treatment against SARS-CoV-2 infection in the hamster model. Hematology For each necropsied cc by nc, a complete social and humanities sciences careers was performed within 15 minutes of sampling on a ProCyte Dx analyser social and humanities sciences laboratories, Westbrook, ME).

List of primers used in this study. Subgenomic viral RNA in nasal turbinates. Nasal turbinates were harvested at day 2 post-infection (D2) or day 5 post-infection (D5). A complete blood count analysis was performed as described in the methods section.
