On day 4 post infection, Syrian hamsters infected with the D614G strain and the omicron SARS-CoV-2 variant had a cumulative lung pathology score of 7.5 and 1.75 (close to the baseline score of untreated, non-infected hamsters), respectively. In comparison to the ancestral D614G strain and other variants of concerns, the omicron is unable to proliferate well in the lower respiratory tract of Syrian hamsters.

Hamsters infected with 103 TCID50 of BavPat (D614G) strain showed median viral RNA copies of 4 x 106/mg of lung tissue, infectious viral loads of 2 x 104/mg of lung tissue , and weight change of 0.65%. Hamsters infected with 103 TCID50 omicron (B.1.1.529) SARS-CoV-2 variant showed median viral RNA copies of 3 x 103/mg of lung tissue, no infectious viral loads, and weight gain of about 3.8%. Highly mutated spike of the omicron variant is better adapted to human ACE2 receptor when compare to ACE2 receptor of the hamster.

Instilling the S1 subunit of SARS-CoV-2 Spike protein (400 µg/kg in 2ml/kg body weight) in K18-hACE2 transgenic mice exhibited a decline in body weight, increase in white blood cells and protein concentrations in bronchoalveolar lavage fluid (BALF), upregulation of multiple inflammatory cytokines in BALF and serum, histological evidence of lung injury, and activation of signal transducer and activator of transcription 3 (STAT3) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathways in the lung. A single exposure of K18-hACE2 mice to SARS-CoV-2 Spike Protein S subunit S1 may represent a valid model of COVID-19, allow the study of the molecular mechanisms of SARS-CoV-2 induced lung injury and be useful in the investigation of potential new therapeutic approaches to the management of COVID-19 as well as future coronavirus-dependent respiratory diseases.

4 Hamsters infected with Del-mut-1 SARS-CoV-2 viruses showed diffuse alveolar wall thickening and peribronchiolar infiltration in the lungs and no bodyweight loss. Del-mut-1 (a 30 bp deletion at S1/S2 junction) attenuated variant has reduced its ability to cause disease in the hamster animal model

Hamsters infected with mutant SARS-CoV-2 (G614 virus) showed higher viral load in the nasal washes and the tracheae, but not in the lungs, than those of Hamsters infected with WT SARS-CoV-2 (D614 virus). Infected hamsters from both groups showed similar weight loss.

Transgenic type I interferon knockout (IFNAR/-) mice, inoculated intranasally with SARS-CoV-2 showed infections in tissues including lungs, heart, stomach, intestines, liver, spleen and kidneys. Lungs with hyperemia, regional consolidation and subpleural air accumulation was observed on necropsy.

2 aged cynomolgus macaques infected with SARS-CoV-2 had 0-5% of lungs affected, and leukocyte infiltration with type I & II pneumocytes affected at 4 days post-infection. Organs affected were also noticed for SARS-CoV and MERS-CoV.
