SARS-CoV-2 Delta variant induces severe damages in the nasal cavity from the first day post-infection in the Syrian hamster model.

Maxime Fusade-Boyer, Adèle Gambino, Laëtitia Merle, Audrey Saint-Albin, Ophélie Grard, Juliette Jacquelin, Younes Boujedli, Hélène Huet, Meriadeg Ar Gouilh, Sandra Martin‐Latil, Bernard Klonjkowski, Nicolas Meunier, Sophie Le Poder

This study compares early nasal cavity damage caused by SARS-CoV-2 D614G, Delta, and Omicron variants in Syrian hamsters, finding Delta causes more rapid viral spread and damage at 1 dpi.

Massive transient damage of the olfactory epithelium associated with infection of sustentacular cells by SARS-CoV-2 in golden Syrian hamsters

Bertrand Bryche, Audrey Saint-Albin Deliot, Séverine Murri, Sandra Lacôte, Coralie Pulido, Meriadeg Ar Gouilh, Sandrine Lesellier, Alexandre Servat, Marine Wasniewski, Evelyne Picard Meyer, Élodie Monchâtre-Leroy, Romain Volmer, Olivier Rampin, Ronan Le Goffic, Philippe Marianneau, Nicolas Meunier

This study shows SARS-CoV-2 infection causes rapid and severe damage to the olfactory epithelium in golden Syrian hamsters, primarily through infection of sustentacular cells and immune cell infiltration, leading to anosmia.
