From Deer-to-Deer: SARS-CoV-2 is efficiently transmitted and presents broad tissue tropism and replication sites in white-tailed deer

Viral shedding dynamics in nasal and oral secretions and feces following SARS-CoV-2 inoculation in white-tailed deer.
A) SARS-CoV-2 RNA load assessed in nasal and oral secretions and feces of controls (animals no. 34, 67, 84, no shown) and six inoculated fawns (animals no. 33, 65, 79, 80, 88, and 116). Nasal, oral and rectal swabs collected on days 0, 2–7, 9, 11, 14, and 22 post-inoculation (pi) were tested for the presence of SARS-CoV-2 RNA by real-time reverse transcriptase PCR (rRT-PCR). B) Infectious SARS-CoV-2 load in nasal and oral secretions and feces was assessed by virus titration in RT-rPCR-positive samples. Virus titers were determined using end point dilutions and expressed as TCID50.ml-1. All the controls fawns (uninoculated) remained negative through the experimental period.
