Experimental Infection and Transmission of SARS-CoV-2 Delta and Omicron Variants among Beagle Dogs

초록

We assessed susceptibility of dogs to SARS-COV-2 Delta and Omicron variants by experimentally inocu-lating beagle dogs. Moreover, we investigated trans-missibility of the variants from infected to naive dogs. The dogs were susceptible to infection without clini-cal signs and transmitted both strains to other dogs through direct contact.
